pandas convert header to first row

# best practice is to use the `header=None` parameter
# this way, the initial header will turn into the first row in the dataframe
df = pd.read_csv(file, header=None)

pandas convert first row to header

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

pandas convert first row to header

df = df.T.set_index(0).T

pandas convert first row to header

df.columns = df.iloc[0] 

df = df[1:]

df.head()

pandas dataframe first rows

df.head(n)

pandas first row to header

see the difference between these two lines
#no header
data= pd.read_csv(path, header = None, delim_whitespace=True, error_bad_lines=False)
#with headers
data= pd.read_csv(path, delim_whitespace=True, error_bad_lines=False)
