Preserving column order in Python Pandas DataFrame

Question

Is there a way to preserve the order of the columns in a csv file when read and the write with Python Pandas? For example, in this code

import pandas as pd

         


        

Answer 1

Another workaround is to do this:

import pandas as pd
data = pd.read_csv(filename)
data2 = df[['A','B','C']]  #put 'A' 'B' 'C' in the desired order
data2.to_csv(filename)
