How to split a column in csv file into multiple column in python jupyter?-CodePudding

Hello everyone I am learning python I am new I have a column in a csv file with this example of value:

I want to divide the column programme based on that semi column into two columns for example

program 1: H2020-EU.3.1. program 2: H2020-EU.3.1.7.

This is what I wrote initially

import csv
import os
with open('IMI.csv', 'r') as csv_file:
    csv_reader = csv.reader(csv_file)
    
    with open('new_IMI.csv', ''w') as new_file:
              csv_writer = csv.writer(new_file, delimiter='\t')
              
    #for line in csv_reader:
       # csv_writer.writerow(line)

please note that after i do the split of columns I need to write the file again as a csv and save it to my computer

Please guide me

you can use pandas with the following code:

import pandas as pd
df = pd.read_csv('new_IMI.csv', sep='\t')
df

assuming that you're in a jupyter notebook this will evaluate your dataframe and show the data inside you can access a specific column with df['columnName'] and specific line number with df.iloc[lineNumber]

Try this:

import pandas as pd

df = pd.read_csv('IMI.csv')
df['program 1'], df['program 2'] = df['programme'].str.split(';', 1).str
