Why does my PyCharm console not run my function?

Question

def is_table(tab):
   if len(tab) != 3:
      return False
   valid = (-1, 0, 1)
   for a in range(0, 3):
      if len(tab[a]) != 3:
         return False
      for b in range(0, 3):
         if tab[a][b] not in valid:
            return False
   return True

When I try to run is_table(((0,0,0),(0,0,0),(0,0,0))) on console, I get this error:

Traceback (most recent call last):
  File "<input>", line 1, in <module>
NameError: name 'is_table' is not defined

Can anyone explain why? My function is clearly defined, but it still doesn't run on console.

The python console dont know about your files functions. First, edit your file name, removing any space, e.g., jogo_do_galo.py (or another name, like jogo_do_mengao).

Open the python console, and try:

>>> from jogo_do_galo import *
>>> tab = ((True, 0, 0), (0, 0, 0), (0, 0, 0))
>>> eh_tabuleiro(tab)

This will work.

Did you define the function inside the console, or in a separate file?

If you defined the function in a separate file, you'll need to run the file before the function will be recognized by the console.

I defined it in a separate file. I have run the file multiple times, and it still does not recognize it. Any other guesses? Maybe I could upload a print screen of my code or something – sousa16 Nov 24 '20 at 02:26
@sousa16 Did you make sure that the console indicated that a file has been run? – Ann Zen Nov 24 '20 at 02:28
how would I do that? I'm relatively new to coding, sorry. – sousa16 Nov 24 '20 at 02:29
from [your file name] import * – Zhubei Federer Nov 24 '20 at 02:29
@sousa16 A screenshot would help. – Ann Zen Nov 24 '20 at 02:31
I double clicked the file and pressed run – sousa16 Nov 24 '20 at 02:32
Just uploaded the screenshot. – sousa16 Nov 24 '20 at 02:33
and how could I fix this? – sousa16 Nov 24 '20 at 02:35
@sousa16 Run `python yourfile.py` in the console. – Ann Zen Nov 24 '20 at 02:36
it returns invalid syntax because of the space – sousa16 Nov 24 '20 at 02:38
@sousa16 Use double quotes around your filename: `python "yourfile.py"`. – Ann Zen Nov 24 '20 at 02:38
still returns invalid syntax. I am running this on pycharm console, is that correct? Just checking to see if maybe I should run it on Terminal. But I'm pretty sure I should be able to run what I was trying to run on console – sousa16 Nov 24 '20 at 02:41
@sousa16 I found [an answer](https://stackoverflow.com/a/26357907/13552470) here. – Ann Zen Nov 24 '20 at 03:44

Found an answer. Right-clicked on file name, settings, run on console.
