I am trying to name keys in my dictionary in a generic way because the name will be based on the data I get from a file. I am a new beginner to Python and I am not able to solve it, hope to get answer from u guys.
For example:
from collections import defaultdict
dic = defaultdict(dict)
dic = {}
if cycle = fergurson:
dic[cycle] = {}
if loop = mourinho:
a = 2
dic[cycle][loop] = {a}
Sorry if there is syntax error or any other mistake.
The variable fergurson and mourinho will be changing due to different files that I will import later on.
So I am expecting to see my output when i type :
dic[fergurson][mourinho]
the result will be:
>>>dic[fergurson][mourinho]
['2']
It will be done by using Python
Naming things, as they say, is one of the two hardest problems in Computer Science. That and cache invalidation and off-by-one errors.
Instead of focusing on what to call it now, think of how you're going to use the variable in your code a few lines down.
If you were to read code that was
for filename in directory_list:
print filename
It would be easy to presume that it is printing out a list of filenames
On the other hand, if the same code had different names
for a in b:
print a
it would be a lot less expressive as to what it is doing other than printing out a list of who knows what.
I know that this doesn't help what to call your 'dic' variable, but I hope that it gets you on the right track to find the right one for you.
i have found a way, if it is wrong please correct it
import re
dictionary={}
dsw = "I am a Geography teacher"
abc = "I am a clever student"
search = re.search(r'(?<=Geography )(.\w+)',dsw)
dictionary[search]={}
again = re.search(r'(?<=clever )(.\w+)' abc)
dictionary[search][again]={}
number = 56
dictionary[search][again]={number}
and so when you want to find your specific dictionary after running the program:
dictionary["teacher"]["student"]
you will get
>>>'56'
This is what i mean to

I need help unscrambling this code. I am only allowed to use these specific lines of code, but I need to 'unscramble' it to make it work. To me, this code looks good but I don't seem to get it to work so I would like to find out why this is the case.
The assignment that I am trying to solve is as follows:
Read in the file using the csv reader and build a dictionary with the tree species as the key and a count of the number of times the tree appears. Use the "in" operator to see if a tree has been added, and if not set it to 1.
Print the dictionary with the counts at the end.
My code is as follows:
from BrowserFile import open as _
import csv
with open("treeinventory.csv", "r", newline='') as f:
count = {}
reader = csv.reader(f)
for yard in reader:
for tree in yard:
if tree in count:
count[tree] = 1
else:
count[tree] = count[tree] + 1
print(count)
I would love if someone can help me and also explain why this code is not able to work as it is, i am trying to learn and this would be very helpful!
thank you!
Generally, we don't solve "homework" problems on SO. You should also try to ask specific questions. Also put better titles on your questions. And, as such, I always like to post This to help new question askers out.
Since I'm here: The answer to your assignment is that line 9 and line 11 are swapped.
This is because the logic seems to set that dict count with the key tree is being set to 1 if the key is in the dict, and add 1 to the value stored at count[tree] if it's not in the dict. This will result in a KeyError exception to be thrown when the value is accessed to do this addition in the statement count[tree] + 1, because, there is no value there yet.
Of course, without the input file, I can't actually run the code to verify it, so please try this out for yourself and update your question with specific issues if any come up.
I am currently stuck at one nested loop problem. I would appreciate it greatly if anyone can offer their insight or tips on how to solve this sticky problem that i am facing.
I am trying to append some values to a list in a for loop. I succeeded in doing that. But how can I get the last list as my variable to use in another loop?
Lets say. I am extracting something by appending them in a list in a for loop.
a=list()
for b in hugo:
a.append(ids)
print(a)
gives me
[1]
[1,2]
[1,2,3]
[1,2,3,4]
But I only need the last line of the list as my variable to be used in another for loop. Can anybody gives me some insights how to do this? Your help is much appreciated. Thanks in advance.
Edit:
Actually I am not trying to get someone to do my homework for me. I am just testing some software programming using python. Here goes:
I am trying to write a script to extract files with the end name of .dat from ANSA pre-processor with the correct name and file ID
For example:
ID Name
1 hugo1.dat
8 hugo2.dat
11 hugo3.dat
18 hugo4.dat
Here is what I have written:
import os
import ansa
from ansa import base
from ansa import constants
from ansa import guitk
def export_include_content():
directory = gutik.UserInput('Please enter the directory to Output dat files:')
ishow=list()
includes=list()
setna=list()
iname=list()
# Set includes variables to collect the elements from a function known as "INCLUDE" from the software
includes=base.CollectEntitites(deck, None, "INCLUDE")
# For loop to get information from the "INCLUDE" function with the end filename ".dat"
for include in includes:
ret=base.GetEntityCardValues(deck, include, 'NAME', 'ID')
ids=str(ret['ID'])
setname=ret['NAME']
if setname.endswith('dat'):
ishow.append(ids)
iname.append(setname)
# Print(ishow) gives me
[1]
[1,8]
[1,8,11]
[1,8,11,18]
# print(iname) gives me
[hugo1]
[hugo1,hugo2]
[hugo1,hugo2,hugo3]
[hugo1,hugo2,hugo3,hugo4]
# Now that I got both of my required list of IDs and Names. It's time for me to save the files with the respective IDs and Names.
for a in ishow:
test=base.GetEntity(deck,'INCLUDE',int(a))
print(a)
file_path_name=directory+"/"+iname
print(file_path_name)
#print(a) gives me
1
8
11
18
#print(file_path_name) gives me
filepath/[hugo1,hugo2,hugo3,hugo4]
filepath/[hugo1,hugo2,hugo3,hugo4]
filepath/[hugo1,hugo2,hugo3,hugo4]
filepath/[hugo1,hugo2,hugo3,hugo4]
# This is the part I got stuck. I wanted the output to be printed in this order:
1
filepath/hugo1
8
filepath/hugo2
11
filepath/hugo3
18
filepath/hugo4
But it doesnt work well so far for me, that's why I am asking whether you all can provide me some assistance on solving this problem :) Helps appreciated!! Thanks all
Your problem is with the code indent:
a=list()
for b in hugo:
a.append(ids)
print(a)
Use a dictionary instead of having 2 separate list for ids and names of includes
The code below creates a dictionary with include id as keys and the corresponding include's name as the value. later this dict is used to print file name
In case you want to save each include as separate file,First isolate the include using "Or"(API) then we have an API for each deck in ANSA to do save files(make sure to enable optional argument 'save visible').for example for NASTRAN it is OutputNastran you can search it in the API search tab in the script editor window
dict={}
for include in includes:
ret=base.GetEntityCardValues(deck, include, 'NAME', 'ID')
ids=str(ret['ID'])
setname=ret['NAME']
if setname.endswith('.dat'):
dict[ids]=setname
for k, v in dict.items():
test=base.GetEntity(deck,'INCLUDE',int(k))
file_path_name=directory+"/"+v
print(file_path_name)
Hope this helps
Assuming ids is actually just the elements in hugo:
a=[id for id in hugo]
print(a)
Or
a=hugo.copy()
print(a)
Or
print(hugo)
Or
a=hugo
print(a)
Or
string = "["
for elem in hugo:
string.append(elem + ",")
print(string[:-1] + "]")
Edit: Added more amazing answers. The last is my personal favourite.
Edit 2:
Answer for your edited question:
This part
for a in ishow:
test=base.GetEntity(deck,'INCLUDE',int(a))
print(a)
file_path_name=directory+"/"+iname
print(file_path_name)
Needs to be changed to
for i in range(len(ishow)):
test=base.GetEntity(deck,'INCLUDE',int(ishow[i]))
file_path_name=directory+"/"+iname[i]
The print statements can be left if you wish.
When you are trying to refer to the same index in multiple lists, it is better to use for i in range(len(a))so that you can access the same index in both.
Your current code has the loop printing every single time it iterates through, so move the print statement left to the same indent level as the for loop, so it only prints once the for loop has finished running its iterations.
a=list()
for b in hugo:
a.append(ids)
print(a)
Basically, I have a troubleshooting program, which, I want the user to enter their input. Then, I take this input and split the words into separate strings. After that, I want to create a dictionary from the contents of a .CSV file, with the key as recognisable keywords and the second column as solutions. Finally, I want to check if any of the strings from the split users input are in the dictionary key, print the solution.
However, the problem I am facing is that I can do what I have stated above, however, it loops through and if my input was 'My phone is wet', and 'wet' was a recognisable keyword, it would go through and say 'Not recognised', 'Not recognised', 'Not recognised', then finally it would print the solution. It says not recognised so many times because the strings 'My', 'phone' and 'is' are not recognised.
So how do I test if a users split input is in my dictionary without it outputting 'Not recognised' etc..
Sorry if this was unclear, I'm quite confused by the whole matter.
Code:
import csv, easygui as eg
KeywordsCSV = dict(csv.reader(open('Keywords and Solutions.csv')))
Problem = eg.enterbox('Please enter your problem: ', 'Troubleshooting').lower().split()
for Problems, Solutions in (KeywordsCSV.items()):
pass
Note, I have the pass there, because this is the part I need help on.
My CSV file consists of:
problemKeyword | solution
For example;
wet Put the phone in a bowl of rice.
Your code reads like some ugly code golf. Let's clean it up before we look at how to solve the problem
import easygui as eg
import csv
# # KeywordsCSV = dict(csv.reader(open('Keywords and Solutions.csv')))
# why are you nesting THREE function calls? That's awful. Don't do that.
# KeywordsCSV should be named something different, too. `problems` is probably fine.
with open("Keywords and Solutions.csv") as f:
reader = csv.reader(f)
problems = dict(reader)
problem = eg.enterbox('Please enter your problem: ', 'Troubleshooting').lower().split()
# this one's not bad, but I lowercased your `Problem` because capital-case
# words are idiomatically class names. Chaining this many functions together isn't
# ideal, but for this one-shot case it's not awful.
Let's break a second here and notice that I changed something on literally every line of your code. Take time to familiarize yourself with PEP8 when you can! It will drastically improve any code you write in Python.
Anyway, once you've got a problems dict, and a problem that should be a KEY in that dict, you can do:
if problem in problems:
solution = problems[problem]
or even using the default return of dict.get:
solution = problems.get(problem)
# if KeyError: solution is None
If you wanted to loop this, you could do something like:
while True:
problem = eg.enterbox(...) # as above
solution = problems.get(problem)
if solution is None:
# invalid problem, warn the user
else:
# display the solution? Do whatever it is you're doing with it and...
break
Just have a boolean and an if after the loop that only runs if none of the words in the sentence were recognized.
I think you might be able to use something like:
for word in Problem:
if KeywordsCSV.has_key(word):
KeywordsCSV.get(word)
or the list comprehension:
[KeywordsCSV.get(word) for word in Problem if KeywordsCSV.has_key(word)]
I'm using Python and "requests" to practice the use of API. I've had success with basic requests and parsing, but having difficulty with list comprehension for a more complex project.
I requested from a server and got a dictionary. From there, I used:
participant_search = (match1_request['participantIdentities'])
To convert the values of the participantIdentities key to get the following data:
[{'player':
{'summonerName': 'Crescent Bladex',
'matchHistoryUri': '/v1/stats/player_history/NA1/226413119',
'summonerId': 63523774,
'profileIcon': 870},
'participantId': 1},
My goal here is to combine the summonerId and participantId to one list. Which is easy normally, but the order of ParticipantIdentities is randomized. So the player I want information on will sometimes be 1st on the list, and other times third.
So I can't use the var = list[0] like how I would normally do.
I have access to summonerId, so I'm thinking I can search the list the summonerId, then somehow collect all the information around it. For instance, if I knew 63523774 then I could find the key for it. From here, is it possible to find the parent list of the key?
Any guidance would be appreciated.
Edit (Clarification):
Here's the data I'm working with: http://pastebin.com/spHk8VP0
At line 1691 is where participant the nested dictionary 'participantIdentities' is. From here, there are 10 dictionaries. These 10 dictionaries include two nested dictionaries, "player" and "participantId".
My goal is to search these 10 dictionaries for the one dictionary that has the summonerId. The summonerId is something I already know before I make this request to the server.
So I'm looking for some sort of "search" method, that goes beyond "true/false". A search method that, if a value is found within an object, the entire dictionary (key:value) is given.
Not sure if I properly understood you, but would this work?
for i in range(len(match1_request['participantIdentities'])):
if(match1_request['participantIdentities'][i]['summonerid'] == '63523774':
# do whatever you want with it.
i becomes the index you're searching for.
ds = match1_request['participantIdentities']
result_ = [d for d in ds if d["player"]["summonerId"] == 12345]
result = result_[0] if result_ else {}
See if it works for you.
You can use a dict comprehension to build a dict wich uses summonerIds as keys:
players_list = response['participantIdentities']
{p['player']['summonerId']: p['participantId'] for p in players_list}
I think what you are asking for is: "How do I get the stats for a given a summoner?"
You'll need a mapping of participantId to summonerId.
For example, would it be helpful to know this?
summoner[1] = 63523774
summoner[2] = 44610089
...
If so, then:
# This is probably what you are asking for:
summoner = {ident['participantId']: ident['player']['summonerId']
for ident in match1_request['participantIdentities']}
# Then you can do this:
summoner_stats = {summoner[p['participantId']]: p['stats']
for p in match1_request['participants']}
# And to lookup a particular summoner's stats:
print summoner_stats[44610089]
(ref: raw data you pasted)
I'm building a de-identify tool. It replaces all names by other names.
We got a report that <name>Peter</name> met <name>Jane</name> yesterday. <name>Peter</name> is suspicious.
outpout :
We got a report that <name>Billy</name> met <name>Elsa</name> yesterday. <name>Billy</name> is suspicious.
It can be done on multiple documents, and one name is always replaced by the same counterpart, so you can still understand who the text is talking about. BUT, all documents have an ID, referring to the person this file is about (I'm working with files in a public service) and only documents with the same people ID will be de-identified the same way, with the same names. (the goal is to watch evolution and people's history) This is a security measure, such as when I hand over the tool to a third party, I don't hand over the key to my own documents with it.
So the same input, with a different ID, produces :
We got a report that <name>Henry</name> met <name>Alicia</name> yesterday. <name>Henry</name> is suspicious.
Right now, I'm hashing each name with the document ID as a salt, I convert the hash to an integer, then subtract the length of the name list until I can request a name with that integer as an indice. But I feel like there should be a quicker/more straightforward approach ?
It's really more of an algorithmic question, but if it's of any relevance I'm working with python 2.7 Please request more explanation if needed. Thank you !
I hope it's clearer this way รด_o Sorry when you are neck-deep in your code you forget others need a bigger picture to understand how you got there.
As #LutzHorn pointed out, you could just use a dict to map real names to false ones.
You could also just do something like:
existing_names = []
for nameocurrence in original_text:
if not nameoccurence.name in existing_names:
nameoccurence.id = len(existing_names)
existing_names.append(nameoccurence.name)
else:
nameoccurence.id = existing_names.index(nameoccurence.name)
for idx, _ in enumerate(existing_names):
existing_names[idx] = gimme_random_name()
Try using a dictionary of names.
import re
names = {"Peter": "Billy", "Jane": "Elsa"}
for name in re.findall("<name>([a-zA-Z]+)</name>", s):
s = re.sub("<name>" + name + "</name>", "<name>"+ names[name] + "</name>", s)
print(s)
Output:
'We got a report that <name>Billy</name> met <name>Elsa</name> yesterday. <name>Billy</name> is suspicious.'
