如何重命名 vaex dataframe -Python 中的多列

Question

I am having trouble renaming multiple columns in vaex dataframe.

I tried

new_name= 'col2'

old_name='col1'

vaex_data.rename(old_name, new_name)

but this approach only works for one column at a time.

Is there something like in pandas where we can pass a dictionary to rename multiple columns?

I didn't find anything in docs. Is there any trick to achieve this.

Answer 1

df.rename(columns={'col': 'col1'}, inplace=True)
