Change Names of Column after iterating over every column names in pandas

I want to change the names of every column of my dataframe iterating over each column names

I am able to change the column names one by one but i want to use a for loop in order to change all column names

for i in range(0,len(flattened.columns)):
    flattened.rename(columns={flattened.columns[i]: "P" + str(i)})

You could just create the dictionary for rename in a list comprehension and then apply it to all columns in a single step, like so:

flattened.rename(
    columns = {
        column_name: 'P' + str(index) for index,column_name in enumerate(flattened.columns)
    }
)

Is this what you are looking for?
