How can I copy an entire column of data (the number of rows are not fixed) to a new column in the same excel file, in Python?

Question

I have an excel file containing a column of 'Usernames' and I want to copy-paste that data into the adjacent column in the same sheet and call it 'Passwords'. All this must be done in a Python program.

Answer 1

You can use pandas to read the excel sheet and then copy the column username to a new column called password and then save it with the same name.

You can do it like this:

df = pd.read_excel('testsheet.xlsx')

df['password'] = df['username']

df.to_excel("testsheet.xlsx", index=False)
