changing column names in pandas ( Index does not support mutable operations- )

I have this current column name:

print(common_nodes_df.columns[0])
('0', '1')

but when I try to change it to:

common_nodes_df.columns[0] = 1

I get this error:

Index does not support mutable operations

What could I do to get around this?

>Solution :

You must replace the whole column names. In your case,

df.columns = [1] + list(df.columns[1:])
