I was web scrapping and trying to remove , from date for csv file but it is not happening I am unable to understand what is wrong with my code

code:
i=0
with open(filename,“w”,encoding=“utf-8”) as f:
header_string=’,’.join(column_titles)
header_string+=’\n’
f.write(header_string)
for row in table_rows:
i=i+1
row_string=""
#date is in 2nd column
if(i==2):
for w in row[2]:

            w=w.replace(',',' ')
            row_string+=w
       
    row_string+=','.join(row)
    row_string+='\n'
    f.write(row_string)
    i++

import pandas as pd
df=pd.read_csv(‘android_version_history.csv’)
df.head()
