So I'm trying to create a software which uses a csv database with pandas for users. I'm not using indexes. My problem is that when I'm trying to update a cell for example: 'Adress' label, it works well the first time but afterwards it keeps adding columns and indexes everytime I update the dataframe. I'm still new to Python and I'm really trying but I couldn't find anything usefull for this one. This is my code for updating the database.
nFirstName = input('Enter new first name: ')
df = pd.read_csv('../Data/Users.csv')
df.loc[df['Username'] == username, ['First Name']] = nFirstName
df.to_csv('../Data/Users.csv')
