What does it mean by ' return' in cooding?and why it is use??

Answer 1

I want you to take a close look at this code for a minute.

def square(x):
return x * x

n = square(4)
print(n)

After I declared the "square" function, I had the result of square(4) stored in n, so n = 16.

Answer 2

return tells a function to stop execution and give the value it evaluated back to the caller, killing the function in the process.
