Check how long function is currently running Python

Question

So lets say I have the function:

def f(x):
    for i in range(x):
        print(i**2)
    return x

I want to implement this:

print(f(99999999))

if f.runTime() > 0.1:
    #DoSomething()

So it will call the function, but will DoSomething() if f() is taking longer than 0.1s (even before f() returns!)

So no, the time module is not what I'm looking for.

Answer 1

As some people suggested, the good option here is using threads, you can check the documentation or this example .

If you don't want to get in there and your time checking must not be very precise, you can do like this:

import time
def f(x):
    start_time = time.time()
    for i in range(x):
        if time.time() - start_time < TIME_LIMIT:
            print(i**2)
        else:
            raise Exception('execution time exceded')
    return x

try:
   print(f(99999999))
except Exception as error:
   print(error)

this is a worse solution because it will lose some execution time while checking in each iteration, but you can try if this works for you.
