The programmer was expecting the following program to print 200. What does it print instead? Why does it print what it does?

def proc(x):

x = 2*x*x

def main():

num = 10

proc(num)

print(num)

main() 

Need some help please. This is in python. I do not understand these two questions.

Is the following program legal since the variable x is used in two different places (proc and main)? Why or why not?

def proc(x):

return 2*x*x

def main():

x = 10

print(proc(x))

main()
