7.3 Return Values

3 practice questionsNot yet reviewed

Notes

The return statement sends a value back to the caller and ends the function. print only displays a value.

def square(n):
return n * n

result = square(6)
print(result)

This prints 36. The returned value is stored in result.
Code after a return in the same function does not run.
A function with no return gives back None.
Returned values can be used in calculations: square(3) + square(4) is 9 + 16 = 25.

What does def f(x): return x + 1 followed by print(f(f(3))) display?

What does def g(n): print(n * 2) followed by y = g(4); print(y) show at the end?

What does def h(): return 1; print(2), when h() is called, do with the print line?

Anything after return in the same block is skipped.
