Python Pandas Replacing Header with Top Row

The dataframe can be changed by just doing

df.columns = df.iloc[0]
df = df[1:]

Then

df.to_csv(path, index=False) 

Should do the trick.

new_header = df.iloc[0] #grab the first row for the header
df = df[1:] #take the data less the header row
df.columns = new_header #set the header row as the df header
