berkorbay / pandas_reorder_columns.py
Created April 18, 2022 14:37
Small function to reorder columns using Pandas. This is a quick and dirty approach. I'm pretty sure there are better alternatives.
import pandas as pd
def pd_reorder_cols(df, d):
"""
Reorders the position of columns with the given specs dictionary.
"""
cl = list(df.columns)
for k1, v1 in d.items():
k1_ix = cl.index(k1)
cl.pop(k1_ix)
