I noticed a bug in my program and the reason it is happening is because it seems that pandas is copying by reference a pandas dataframe instead of by value. I know immutable objects will always be passed by reference but pandas dataframe is not immutable so I do not see why it is passing by reference. Can anyone provide some information?
Thanks!

Method 1
All functions in Python are “pass by reference”, there is no “pass by value”. If you want to make an explicit copy of a pandas object, try new_frame = frame.copy().
