Explanation:
CODE:
global_var = "global" #accessible to all functions
def level0():
level0_var = "level 0" #accessible to level 0,1,2,3
print();
print("Level 0 function:")
print("global variable: ",global_var)
print("local variable 0: ",level0_var)
def level1():
print();
print("Level 1 function:")
level1_var = "level 1" ##accessible to level 1,2,3
print("global variable: ",global_var)
print("local variable 0: ",level0_var)
print("local variable 1: ",level1_var)
def level2():
print();
print("Level 2 function:")
level2_var = "level 2" #accessible to level 2,3
print("global variable: ",global_var)
print("local variable 0: ",level0_var)
print("local variable 1: ",level1_var)
print("local variable 2: ",level2_var)
def level3():
print();
print("Level 3 function:")
level3_var = "level 3" #accessible to level 3
print("global variable: ",global_var)
print("local variable 0: ",level0_var)
print("local variable 1: ",level1_var)
print("local variable 2: ",level2_var)
print("local variable 3: ",level3_var)
level3()
