我怎样才能做到这一点?我试过了:

     index = pandas.Index(range(20))

but it's giving me the following error:

但它给了我以下错误:

3 个解决方案

#1

you can do

你可以做

followers_df.index = range(20)

#2

followers_df.reset_index()
followers_df.reindex(index=range(0,20))

#3

When You are Not Sure of the Number of Rows, Then u Can Do this Way

当你不确定行数时,你可以这样做

followers_df.index = range(len(followers_df))
