I use python
How many function calls occur when this code is run?
def A():
B()
C()
def B():
C()
def C():
return
B()
A()
The second question is what is the value of x after this code is run?
x = 12
def A():
global x
x = 5
def B():
x =7
A()
B()
The third question is what is the value of L after this code is run..?
L=[1,2,3]
def A():
global L
L[1] =4
def B():
L[2] =2
A()
B()
I'm going over my past final exam questions but when i try to run these codes on python, they print nothing.
