Question

How many times will the foo() function be called in the following code sample?

def foo():
print(""hi"")
def bar():
foo()
foo()
def fun():
for x in range(5):
bar()
a.10
b.15
c.0
d.infinite

Answer 1

In the given code, the foo() function will be called a total of 10 times because it is called twice inside the bar() function, which is then run 5 times inside the fun() function loop.

Step-by-step explanation:

The foo() function is called inside the bar() function, which in turn is called inside the fun() function loop. The foo() function is called twice every time the bar() function is executed. The bar() function is called in a loop that runs 5 times within the fun() function. Therefore, the total number of times the foo() function will be called is 2 (calls within bar) multiplied by 5 (iterations of the loop in fun), which equals 10.
