Conditions in multiple functions (python)

Question

I have this code, but why when the time reach 0:30 nothing happens, where is my error?:

import datetime

def a():

   timing = [0, 30] #hours, #minutes
   while True:
       now = datetime.datetime.now()
       datas = [now.hour, now.minute]    
       if datas == timing:
            a.x = 5
        
def b():
    a()
    if "he" == "he":
        print(2)
    
         if a.x == 5:
             print("VER")
    
b()

Are you defining "a.x" within a()? Because you can only do that within classes, not functions. — GIOVANNI QUINONES VALDEZ

You never break out of the while loop, so a() never returns. — Barmar

@GIOVANNIQUINONESVALDEZ Functions are class instance, so you can create attributes on them. — Barmar

I believe because you don't leave the while loop. You should add a break to if condition. It means if a.x is set, then program should leave the function a and get back to function b.

def a():

   timing = [18, 54] #hours, #minutes
   while True:
       now = datetime.datetime.now()
       datas = [now.hour, now.minute]    
       if datas == timing:
            a.x = 5
            break
        
def b():
    a()
    if "he" == "he":
        print(2)
    
        if a.x == 5:
            print("VER")
    
b()

he said he tried this and it didn't work.

Are you sure you change the values in timing based on the current time? I mean if you run the code now, nothing happens till we get datas == timing. So for testing, you should change the timing!

See his last comment. It did work, he just forgot to restart after editing.

@amir It works thanks, and what if i want to avoid the "break",is there a way to run the functions without the "break"?

@TreesJin you can use return instead of break
