我不确定无效令牌的含义

Question

I'm not sure what it means by invalid token. This is the error log

runfile('C:/Users/evilq/Documents/PBPKmodel2.py', wdir='C:/Users/evilq/Documents')

SyntaxError: invalid token

This is the code:

Answer 1

01 is invalid. The integer number one in python is represented like this: 1

In python 2 starting with a 0 meant octal notation, but in python 3 it was deprecated to prevent mistakes. 0o1 is octal and 1 is decimal, 01 is syntax error now.
