Consider the code given below:
b = 100
def test(a):
............... #missing statement
b = b + a
print(a, b)
test(10)
print(b)
Which of the following statements should be given in the blank for #Missing Statement, if the output produced is 110?
- global a
- global b = 100
- global b
- global a = 100
Answer
global b
Reason — When we want to modify a global variable within a function in Python, we need to use the global keyword followed by the name of the global variable. In this case, since the variable b is declared as a global variable outside the function, we need to declare it as a global variable again inside the function using global b before attempting to modify its value.
