My guess is that you saved a shell session as a .py file, loaded it into 
an editor window, and tried to run it without editing out the non-code 
text.  Given
"""
Python 3.9.0b3 (tags/v3.9.0b3:b484871, Jun  9 2020, 20:36:59) [MSC 
v.1924 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license()" for more information.
 >>> a = 3
"""
you have to remove everything before 'a = 3', and so on through the 
file.  If you did something else, please explain.
