I'm practicing use python to commit rollback MongoDB (Pymongo)
For example, I have two collections, one collection store all amount of money of each user and log collection is saving data of with roll or input money in bank
total_money_collection {"user": "Joy" , "total_money" : 100, "ID" : 999}
log_money_collection {"user": "Joy" , "in_out_put_money" : null , "ID" : 999}
I need a hand for simpler way, maybe there is a short pymongo command,or MongoDB can do such operation that just extract the result is fine etc.
If I input from log_money_collection {"user": "Joy" , "in_out_put_money" : -7 , "ID" : 999},
how can "in_out_put_money" column effect "total_money" column
Expected output:
total_money_collection {"user": "Joy" , "total_money" : 93, "ID" :
999}
This is my code (I made lot of make an unnecessary move, I believe there is a simpler way):

A simple step of commit rollback MongoDB with account money I turn a huge circle to get it, I need a hand for simpler way, maybe there is a short pymongo command,or MongoDB can do so that just extract the result is fine etc
the same concept make ur {"user": "Joy" , "total_money" : 93, "ID" : 999},
the "total_money" become lesser by subtracting them, for sure U can't directly do that, like python (4 - 1 something)....
here is the code:
import pymongo
import datetime
import json
from bson.objectid import ObjectId
from bson import json_util
import re
myclient = pymongo.MongoClient("mongodb://localhost/")
mydb = myclient["(practice_10_14)-0004444"]
# UD_db_data means update
def UD_db_data(mycol , myquery_json, newvalues_json, one_or_many_bool):
if one_or_many_bool == True:
x = mycol.update_many(myquery_json, newvalues_json)
else:
x = mycol.update_one(myquery_json, newvalues_json)
return x
# Quy_data = query find db_data
def Quy_data( mycol ,find_values_json , one_or_many_bool):
try:
if one_or_many_bool:
x = []
for y in mycol.find(find_values_json):
x.append(y)
else:
x = mycol.find_one(find_values_json)
return x
except Exception as e:
msg_fail_reason = "error in ins_data function"
return msg_fail_reason
mycol_one = mydb["10_20_cash_all"]
mycol_two = mydb["10_20_cash_log"]
mycol_3rd = mydb["10_20_cash_info"]
# already store 100$ in bank
# doc_two = {"ID" : 100998 , "Cash_log$" : 5 } # withdraw 5$ from bank
doc_two = input("Enter ID and log amount$: ")
doc_3rd = input("Enter extra info: ")
doc_two_dic = json.loads(doc_two)
doc_3rd_dic = json.loads(doc_3rd)
# doc_3rd = {"note" : "today is good" }
ID_input = doc_two_dic['ID']
print("ur id is :" + str(ID_input))
doc_one = {"ID" : ID_input}
with myclient.start_session() as s:
cash_all_result = mycol_one.find_one(doc_one, session=s)
def cb(s):
try:
while True:
cash_all_result = mycol_one.find_one(doc_one, session=s)
mycol_two.insert_one(doc_two_dic, session=s)
# print( 3/0 )
mycol_3rd.insert_one(doc_3rd_dic, session=s)
print( "now total is :" + str(cash_all_result['Cash_$']) )
Cash_total_int = int(cash_all_result['Cash_$'])
log_int = int(doc_two_dic['Cash_log$'])
if Cash_total_int < log_int:
print("error: withdraw is over ur balance")
break
new_Cash_total = Cash_total_int - log_int
print("now total is :" + str(new_Cash_total))
newvalues_json = { "$set" : {"Cash_$" : new_Cash_total } }
mycol_one.update_one(doc_one , newvalues_json, session=s)
fail_condition_json = {"ok" : 1 , "fail reason" : "no error "}
print(fail_condition_json)
return fail_condition_json
except Exception as e:
fail_condition_json = {"ok" : 0 , "fail reason" : "error raise on start_session()"}
print(fail_condition_json)
return fail_condition_json
s.with_transaction(cb)
I believe I do the calculation with 3 collection's data
and the output is below
Enter ID and log amount$: {"ID" : 100998 , "Cash_log$" : 23 }
Enter extra info: {"note" : "today is no good" }
ur id is :100998
now total is :72
now total is :49
{'ok': 1, 'fail reason': 'no error '}

i have a sql query which basically retrieves coin names and submits an order for each coin.
However, it only submits an order on one coin and fails to loop through the rest, not sure why thats happening .
import sys
**
import pandas as pd
postgreSQL_select_Query = "SELECT base,quote FROM instrument_static where exchange='ftx'"
cursor.execute(postgreSQL_select_Query)
row=([y for y in cursor.fetchall()])
for i in row:
base=i[0]
quote=i[1]
portfolioItems = [
{
'exchange': 'ftx',
'base': base,
'quote': quote,
'amount': 0.01,
},
]
def init():
username = us
password = passwordVal
initialise(clientId, clientSecret, us, password)
if __name__ == "__main__":
init()
result = construct_portfolio_with_params(us, portname, portfolioItems)
print(result)
You need to initialize portfolioItems prior to the loop, and then you can add to it. Try replacing this snippet of code:
...
row=([y for y in cursor.fetchall()])
portfolioItems = []
for i in row:
base=i[0]
quote=i[1]
portfolioItems.append(
{
'exchange': 'ftx',
'base': base,
'quote': quote,
'amount': 0.01,
}
)
...

I am trying to split first whole text, but there I met another problem is to match keys to values depending on '=' sign. Also there might be some keys with empty values. For ex.:
type = INREQ channel = sid = duration = 1.333 (to get to know that there is an empty value, you need to pay attention on number of spaces. Usually there is 1 space between prev.value and next key). So this example should look like this:
{
"type":"INREQ",
"channel":"",
"sid":"",
"duration":"1.333"
}
Thanks ahead!
Here, one thing pass for duplicate key about "$sid":"msid_1591844511335516_KRRNBSLH2FS"

you can try regulation in python.
here is what i write, it works for your problem.
for convenience i deleted string before "ext_ref...",you can directly truncate the raw string.

Below is the code I have tried, actually I am looking for result like comparision of each key dictionary so my max_value for each dictionary will be like "2539:Mark:35" … same thing for rest other dictionary pls help me here to solve this..
student_data = {2539:{'James':30, 'Mark': 35}, 8214: { 'Michelle': 32,'Mark': 40},7411:{'Travis':28, 'Mark': 45}}
for id,v in student_data.items():
print(id, '-->', student_data[id][0] + ',', max(student_data[id][1].values()))
print('Subjects:', student_data[id][2], '\n')
Using your code as much as possible.
Use find max in dictionary to find key with max value in dictionary
Code
student_data = { 2539: { 'James': 30, 'Mark': 35 }, 8214: { 'Michelle': 32,'Mark': 40 }, 7411: { 'Travis': 28, 'Mark': 45 } }
for id,v in student_data.items(): # v is a dictionary
max_student = max(v, key=v.get) # student name with max
print(f'{id}:{max_student}:{v[max_student]}')
Output
2539:Mark:35
8214:Mark:40
7411:Mark:45
Expanded to input info for student_data

I have a program that compares values from the database and from a CSV file. My program works like this.
Database has values.
User uploads a file (multiple users multiple
files).
The program compares the values from the database and the
CSV files and gives an output.
Which tells me that this particular value was found in this user's file.
But I want the program to show me that if the value was found in the other user's file or not.
Here is a working example.
DB Values = [1,23,33,445,6656,88]
Example values of the CSV files:
File 1 values = [1,23,445,77,66,556,54]
File 2 values = [1,23,45,77,366]
File 3 values = [1,23,5,77,5356,524]
Output needed:
{'1':[(user1, some value),(user2, some value)...]}

Output
Zong, Tata are usernames and the float values is their respective value for the key value of the dictionary.
{'12': [('Zong', ' 0.026')], '213': [('Tata', ' 4.150')], '49': [('Tata', ' 0.531')], '30': [('Zong', ' 0.87')], '454': [('Tata', ' 0.531')], '374': [('Zong', ' 0.87')],
This is what you asked for:
### your data example
db = [1,23,33,445,66,556,88]
us1 = [1,23,445,77,66,556,54]
us2 = [1,23,45,77,366]
### create a list of usernames (to use the string name in dictionary)
userlist = [ "us1", "us2" ]
### intialize the dict for results
values_dict = {}
### open the loop on DB values
for value in db :
# open loop on userlist
for user in userlist :
# if value is found in user list of values
if value in eval(user) :
# if values still NOT a key of results dictionary create the key with the tuple list as values
if value not in values_dict :
values_dict.update({ value : [ ( user, value ) ] })
# else just append the tuple (username, value) to the results dictionary for the DB value corresponding key
else :
values_dict[value].append([ ( user, value ) ])
values_dict
### OUTPUT:
{1: [('us1', 1), [('us2', 1)]], 23: [('us1', 23), [('us2', 23)]], 445: [('us1', 445)], 66: [('us1', 66)], 556: [('us1', 556)]}
but it makes no sense cause it simply check if a value is in the user list of values and add a tuple just to confirm it, it doesn't require all this code, could be simplified a lot. But I'm thinking that I misunderstood your question (please review the english), probably you need to use the DB value as the key to retrieve another value from the user...please review and update
I have a dictionary defined as follows:
SN = {}
SN[0] = {'verb' : 1 }
In my function I make 3 prints as follows:
print graph
print state
print graph[state]
(I do nothing else with these variables) and it returns:
SN
0
S
How is this possible? Why doesn't it return
SN
0
{'verb' : 1}
The whole code :
abstraction= {}
abstraction['de'] = ['déterminant']
abstraction['le'] = ['déterminant']
abstraction['un'] = ['déterminant']
abstraction['beau'] = ['adjectif', 'substantif']
abstraction['dodu'] = ['adjectif', 'substantif']
abstraction['grand'] = ['adjectif', 'substantif']
abstraction['méchant'] = ['adjectif', 'substantif']
abstraction['noirs'] = ['adjectif', 'substantif']
abstraction['petit'] = ['adjectif', 'substantif']
abstraction['desseins'] = ['substantif']
abstraction['loup'] = ['substantif']
abstraction['poulet'] = ['substantif']
abstraction['gosse'] = ["n'importe quoi"]
abstraction['mange'] = ['verbe']
abstraction['dort'] = ['verbe']
SN = {}
SN[0] = {'déterminant' : 1 }
SN[1] = {'adjectif' : 1, 'substantif' : 2 }
SN[2] = {'adjectif' : 3, '' : 'ok' }
SN[3] = {'' : 'ok' }
SV = {}
SV[0] = {'verbe' : 1}
SV[1] = {'transitions' : 'SN', '' : 'ok'}
SV[2] = {'' : 'ok'}
def transitions(data, graph, state = 0, transit = []) :
print 'data avt if data :'
print data
if data :
if 'transitions' in graph[state] :
return transitions(data, graph[state]['transitions'], 0, transit)
symbol = data[0]
if symbol not in abstraction.keys() :
return ['impossible, un des mots n\'est pas reconnu par l\'automate']
for a in abstraction[symbol] : # loop on abstractions
print graph
print state
print graph[state]
if a in graph[state] :
state = graph[state][a]
return transitions(data[1:], graph, state, transit + [a])
else :
return transit + [symbol] + ['impossible']
else :
if '' in graph[state] :
return transit + [graph[state]['']]
else : return transit + ['impossible']
I think your problem here is that graph == "SN", rather than (as you apparently expect) graph == SN.
To put it another way, graph is referencing a str object with value "SN", not the dict object also referenced by the name SN.
Therefore graph[0] is the first character in the string "SN", which is the letter "S".
In the case graph == SN, the output from
print graph
print state
print graph[state]
would be:
{0: {'verb': 1}} # note: not 'SN'
0
{'verb': 1}
Edit:
Now that you've posted your code, this section:
SN = {}
SN[0] = {'déterminant' : 1 }
SN[1] = {'adjectif' : 1, 'substantif' : 2 }
SN[2] = {'adjectif' : 3, '' : 'ok' }
SN[3] = {'' : 'ok' }
creates a dictionary
SN = {0: {'déterminant': 1}, 1: {'adjectif': 1, 'substantif': 2},
2: {'adjectif': 3, '': 'ok'}, 3: {'': 'ok'}}
However, in the next part:
SV[1] = {'transitions' : 'SN', '' : 'ok'}
you assign the string 'SN' to the key 'transitions', not the actual dictionary SN. That should have been:
SV[1] = {'transitions': SN, '': 'ok'}
# ^ no quote marks
Also, as all of your keys are integers starting from zero, you could consider using a list instead of a dictionary, e.g.:
SN = []
SN.append({'déterminant': 1})
SN.append({'adjectif': 1, 'substantif': 2})
