Writes "inconsistent use of tabs and spaces in indentation", what doesn't he like??

Question

Python

try:
        user_counter[message.author.id] += 1
except NameError:
        user_counter[message.author.id] = 1

writes an error in the category "
except NameError:
^
TabError: inconsistent use of tabs and spaces in indentation"
I don’t understand why he writes like that

Answer 1

I don't understand why he writes like that

What is there to understand
Take and translate the phrase with a dictionary. They tell you in plain text that you have tabs mixed with spaces in your indents
