Python - Write a row into an array into a text file-CodePudding

I need to create to file depending on the first digit from 'CompteNum'.

I have started my code as well

import sys
import pandas as pd
import numpy as np
import datetime

C_FILE_SEP = "|"

def main(fic):
    pd.options.display.float_format = '{:,.2f}'.format
    FileFec = pd.read_csv(fic, C_FILE_SEP, encoding= 'unicode_escape')

It seems ok, my concern is to create my 2 files based on criteria. I have tried with unsuccess.

TargetFec = 'Target_' fic datetime.datetime.now().strftime("%Y%m%d-%H%M%S") '.txt'
target = open(TargetFec, 'w')
FileFec = FileFec.astype(convert_dict) 
for row in FileFec.iterrows():

Fec_Cpt = str(FileFec['CompteNum']) 
nb = len(Fec_Cpt)
if (nb > 7):
    target.write(str(row))
target.close()

the result of my target file is not like I expected:

And I expected to obtain line into my target file when CompteNum(0:1) > 7

I have read many posts for 2 days, please some help will be perfect.

There is a sample of my data available here

CodePudding user response：

As I understand it, you want to filter the imported dataframe according to some criteria. You can work directly on the pandas you imported. Look:

# criteria:
verify = df['CompteNum'].apply(lambda number: len(str(number)) > 7)

# filtering the dataframe based on the given criteria:
df[verify] # meets the criteria
df[~verify] # does not meet the criteria

# saving the dataframes:
df[verify].to_csv('<your path>/meets-criterios.csv')
df[~verify].to_csv('<your path>/not-meets-criterios.csv')

Once you have the filtered dataframes, you can save them or convert them to other objects, such as dictionaries.
