Need help to solve the Unnamed and to change it in dataframe in pandas

问题

how set my indexes from "Unnamed" to the first line of my dataframe in python

import pandas as pd

df = pd.read_excel('example.xls','Day_Report',index_col=None ,skip_footer=31 ,index=False)

df = df.dropna(how='all',axis=1)
df = df.dropna(how='all')
df = df.drop(2)

回答1:

To set the column names (assuming that's what you mean by "indexes") to the first row, you can use

df.columns = df.loc[0, :].values

Following that, if you want to drop the first row, you can use

df.drop(0, inplace=True)

Edit

As coldspeed correctly notes below, if the source of this is reading a CSV, then adding the skiprows=1 parameter is much better.
