Here is my function. Trying to get this all to print to one line.
Here is the output ->
config::$var['pdf']['meta']['staff_member_name']
= ";"
The = ";" portion of the string prints to a new line in the console for some reason?
This is totally just a personal hack to help with a repetitious job requirement so i'm not looking for anything fancy.
Here is my function ->
def auto_pdf_config(file):
with open(file) as f:
content = f.readlines()
kill = " = array("
start = "config::$var['intake']"
new_line = ""
for line in content:
if kill not in line:
pass
elif start in line:
new_line = line
x = new_line.replace(kill, "")
y = x.replace(start,"")
pdf_end = ' = ";" '
z = "config::$var['pdf']['meta']{}{}".format(y,pdf_end)
print(z)
it seems you "y" variable has new line in it. you can try to strip it off.
y = x.replace(start,"").strip('\n')
Since x = new_line.replace(kill, ""), y = x.replace(start,""), and new_line is the line of content, it contains endline symbol (\n), that's why this endline symbol is appended before pdf_end. You just need to remove endline symbol from y.
You can do something like that:
y = y.strip('\n')

Consider:
def fix_county_string(s):
""" Insert Docstring """
fp = open("michigan_COVID_08_24_21.txt", "r")
fp.readline()
for line in fp:
county = line[24:43]
x = county.split()
t = x.pop(-1)
s = x.append("County")
return s
fix_county_string(s)
The parameter is s, a string. Every county name ends with the places; if it correctly ends in places, do nothing (simply return s). Otherwise, correct the ending word to be place. Specifically, if not, fix it.
Use:
def fix_county_string():
""" Insert Docstring """
fp = open("michigan_COVID_08_24_21.txt", "r")
s = ''
for line in fp:
county = line[24:43]
x = county.split()
t = x.pop(-1)
x.append("County")
s += line + ' '.join(x)
return s
s = fix_county_string()
I think this is what you are trying to do. You can write back the output in a file.
I'm learning python so I am pretty new to it.
I've been working on a class assignment and iv'e been facing some error, such as the one in the title.
This is my code:
import random
def getWORDS(filename):
f = open(filename, 'r')
templist = []
for line in f:
templist.append(line.split("\n"))
return tuple(templist)
articles = getWORDS("articles.txt")
nouns = getWORDS("nouns.txt")
verbs = getWORDS("verbs.txt")
prepositions = getWORDS("prepositions.txt")
def sentence():
return nounphrase() + " " + verbphrase()
def nounphrase():
return random.choice(articles) + " " + random.choice(nouns)
def verbphrase():
return random.choice(verbs) + " " + nounphrase() + " " + \
prepositionalphrase()
def prepositionalphrase():
return random.choice(prepositions) + " " + nounphrase()
def main():
number = int(input("enter the number of sentences: "))
for count in range(number):
print(sentence())
main()
However, whenever I run it I get an this error:
TypeError: can only concatenate list (not "str") to list.
Now, I know there are tons of question like this but I tried a lot of time, I am not able to fix it, I'm new to programming so I've been learning the basics since last week.
Thank you
Here I've modified the function slightly - it'll fetch every words into a tuple. Use with to open the files - it will close the pointer once the values have been fetched.
I hope this will work for you!
def getWORDS(filename):
result = []
with open(filename) as f:
file = f.read()
texts = file.splitlines()
for line in texts:
result.append(line)
return tuple(result)
I think the problem is in this line:
templist.append(line.split("\n"))
split() will return a list that is then appended to templist. If you're wanting to remove the newline character from the end of the line use rstrip() as this will return a string.
When working with a file, you should use the read() method:
file = f.read()
To split the file to lines and add to a list, you first split, then append line by line.
file = f.read()
lines = file.split("\n")
for line in lines:
templist.append(line)
In your case, you are using the list of lines as-is, so I would write:
file = f.read()
templist = file.split("\n")
Edit 1:
Another useful tool when working with files is f.readline(), which returns the first line when calling it for the first time, second when calling it once again... third... and so on, although the previous ways I showed would be more efficient here.
Edit 2:
When you are done using the file, use the close() method, or start using the file with a with ... as method which closes the file at the end of the code block.
Code example using with ... as (The best written code in this answer):
def getWORDS(filename):
with open(filename, 'r') as f:
file = f.read()
templist = file.split("\n")
return tuple(templist)
Code example using close():
def getWORDS(filename):
f = open(filename, 'r')
file = f.read()
templist = file.split("\n")
f.close()
return tuple(templist)
This is how I would write the full code.
(fixed file opening and reading + fixed capitalization)
import random
def getWORDS(filename):
with open(filename, 'r') as f:
file = f.read()
templist = file.split("\n")
return tuple(templist)
articles = getWORDS("articles.txt")
nouns = getWORDS("nouns.txt")
verbs = getWORDS("verbs.txt")
prepositions = getWORDS("prepositions.txt")
def sentence():
sentence = nounphrase() + " " + verbphrase()
sentence = sentence.split(" ")
sentence[0] = sentence[0].capitalize()
sentence = " ".join(sentence)
return sentence
def nounphrase():
return random.choice(articles).lower() + " " + random.choice(nouns).capitalize()
def verbphrase():
return random.choice(verbs).lower() + " " + nounphrase() + " " + \
prepositionalphrase()
def prepositionalphrase():
return random.choice(prepositions).lower() + " " + nounphrase()
def main():
number = int(input("enter the number of sentences: "))
for count in range(number):
print(sentence())
main()
The script is adding a line break right after the curly braces while writing both strings right after the username. I would think this is because of my source text file has encoding in it adding the breaks but as far as I can tell it does not. Am I misunderstanding how write works? Something simple I'm missing. Been looking at this too long and need a new set of eyes.
users_list = []
users = input("File of User's ")
user_file = open(users + '.txt', 'r')
for i in user_file:
users_list.append(i)
sql_file = open('sql.txt', 'w')
sql_file.write("SELECT MACHINE.NAME AS SYSTEM_NAME, SYSTEM_DESCRIPTION,
MACHINE.IP, MACHINE.MAC, MACHINE.ID as TOPIC_ID FROM MACHINE WHERE
((MACHINE.USER_NAME = '{}') OR ".format(users_list[0]))
for i in users_list:
sql_file.write("(MACHINE.USER_NAME = '{}')".format(i))
sql_file.write(" OR ")
The output of the file looks like this:
SELECT MACHINE.NAME AS SYSTEM_NAME, SYSTEM_DESCRIPTION, MACHINE.IP, MACHINE.MAC, MACHINE.ID as TOPIC_ID FROM MACHINE WHERE ((MACHINE.USER_NAME = 'hnelson
') OR (MACHINE.USER_NAME = 'hnelson
') OR (MACHINE.USER_NAME = 'snery
') OR (MACHINE.USER_NAME = 'jherman
change your line 7 and 8
for i in user_file:
users_list.append(i)
to
for i in user_file:
users_list.append(i.strip())
and it should work as expected.
It is because i is a line from user_file and it ends with \n. i.strip() removes the trailing newline.
I have the below code in one of my configuration files:
appPackage_name = sqlncli
appPackage_version = 11.3.6538.0
The left side is the key and the right side is value.
Now i want to be able to replace the value part with something else given a key in Python.
import re
Filepath = r"C:\Users\bhatsubh\Desktop\Everything\Codes\Python\OO_CONF.conf"
key = "appPackage_name"
value = "Subhayan"
searchstr = re.escape(key) + " = [\da-zA-Z]+"
replacestr = re.escape(key) + " = " + re.escape(value)
filedata = ""
with open(Filepath,'r') as File:
filedata = File.read()
File.close()
print ("Before change:",filedata)
re.sub(searchstr,replacestr,filedata)
print ("After change:",filedata)
I assume there is something wrong with the regex i am using. But i am not able to figure out what . Can someone please help me ?
Use the following fix:
import re
#Filepath = r"C:\Users\bhatsubh\Desktop\Everything\Codes\Python\OO_CONF.conf"
key = "appPackage_name"
value = "Subhayan"
#searchstr = re.escape(key) + " = [\da-zA-Z]+"
#replacestr = re.escape(key) + " = " + re.escape(value)
searchstr = r"({} *= *)[\da-zA-Z.]+".format(re.escape(key))
replacestr = r"\1{}".format(value)
filedata = "appPackage_name = sqlncli"
#with open(Filepath,'r') as File:
# filedata = File.read()
#File.close()
print ("Before change:",filedata)
filedata = re.sub(searchstr,replacestr,filedata)
print ("After change:",filedata)
See the Python demo
There are several issues: you should not escape the replacement pattern, only the literal user-defined values in the regex pattern. You can use a capturing group (a pair of unescaped (...)) and a backreference (here, \1 since the group is only one in the pattern) to restore the part of the matched string you need to keep rather than build that replacement string dynamically. As the version value contains dots, you should add a . to the character class, [\da-zA-Z.]. You also need to assign new value after replacing, so as to actually modify it.
I have alot of files which names are just number. (Starting from 1 to whatever is the maximum number) and each of these files are similar to each other by their "tags" (ObjectID =, X =, Y =, etc.), but the values after those tags are not the same at all.
I wanted to make my job easier from manually copy/pasting the data from one file to another and made a small script using Python (since I am slightly experienced in it).
This is the full script:
import os
BASE_DIRECTORY = 'C:\Users\Tom\Desktop\TheServer\scriptfiles\Objects'
output_file = open('output.txt', 'w')
output = {}
file_list = []
for (dirpath, dirnames, filenames) in os.walk(BASE_DIRECTORY):
for f in filenames:
if 'txt' in str(f):
e = os.path.join(str(dirpath), str(f))
file_list.append(e)
for f in file_list:
print f
txtfile = open(f, 'r')
output[f] = []
for line in txtfile:
if 'ObjectID =' in line:
output[f].append(line)
elif 'X =' in line:
output[f].append(line)
elif 'Y =' in line:
output[f].append(line)
tabs = []
for tab in output:
tabs.append(tab)
tabs.sort()
for tab in tabs:
for row in output[tab]:
output_file.write(row + '')
Now, everything is working fine, the output file looks like this:
ObjectID = 1216
X = -1480.500610
Y = 2610.885742
ObjectID = 970
X = -1517.210693
Y = 2522.842285
ObjectID = 3802
X = -1512.156616
Y = 2521.116210
etc.
But I don't want it to be like that (each value has a new line). I need it to do this for every file:
Read the file.
Remove the tags infront of the values.
Format a single line which will have those values in the output folder. (Let's say I want to make it look like this: "(1216,-1480.500610,2522.842285)" )
Write that line in the output folder.
Repeat for every file.
Any help please?
Hope this helps.
data = open('sam.txt', 'r').read()
>>> print data
ObjectID = 1216
X = -1480.500610
Y = 2610.885742
ObjectID = 970
X = -1517.210693
Y = 2522.842285
ObjectID = 3802
X = -1512.156616
Y = 2521.116210
>>>
Now lets do some string replacements :)
>>> data = data.replace('ObjectID =', '').replace('\nX = ', ',').replace('\nY = ', ',')
>>> print data
1216,-1480.500610,2610.885742
970,-1517.210693,2522.842285
3802,-1512.156616,2521.116210
In your loop, keep track of whether you are 'in' a record:
records = []
in_record = False
id, x, y = 0, 0, 0
for line in txtfile:
if not in_record:
if 'ObjectID =' in line:
in_record = True
id = line[10:]
elif 'X =' in line:
x = line[3:]
elif 'Y =' in line:
y = line[3:]
records.append((id, x, y))
in_record = False
Then you'll have a list of tuples which you can easily write with the csv module.
Find here a version of the loop you have generating the contents.
I rewrote it so the line contents ObjectId, X and Y are in the same line.
It looks that is what you want to do:
for f in file_list:
print f
txtfile = open(f, 'r')
output[f] = []
for line in txtfile:
myline = ''
if 'ObjectID =' in line:
pos = line.rfind("ObjectID =") + len("ObjectID =")
rest = line[pos:]
# Here you set the delimiter after the ObjectID value. Can be ","
numbers = rest.split(" ")
if len(numbers) > 0:
myline.append(numbers[0])
elif 'X =' in line:
pos = line.rfind("X =") + len("X =")
rest = line[pos:]
# Here you set the delimiter after the ObjectID value. Can be ","
numbers = rest.split(" ")
if len(numbers) > 0:
myline.append(numbers[0])
elif 'Y =' in line:
pos = line.rfind("Y =") + len("Y =")
rest = line[pos:]
# Here you set the delimiter after the ObjectID value. Can be ","
numbers = rest.split(" ")
if len(numbers) > 0:
myline.append(numbers[0])
output[f].append(myline)
Note that you need to know which character (in the code the delimiter) separates the names you try to find: ObjectID = from the actual values you want to grab from the line.
Here is what you need. I did not have enough time to write the code for appending the result to a new file. Instead it just prints it, but you get the point.
import os.path
path = "path"
#getting the number of files in your folder
num_files = len([f for f in os.listdir(path)
if os.path.isfile(os.path.join(path, f))])
#function that returns your desired output for a given file
def file_head_ext(file_path, file_num):
with open(file_path + "/" + file_num) as myfile:
head = [next(myfile).split("=") for x in range(3)]
formatted_head = [elm[1].replace("\n",'').replace(" ","") for elm in head]
return(",".join(formatted_head))
for filnum in range(1,num_files):
print(file_head_ext(path, str(filnum)))
