Observe the given Python code carefully:

a=20
def convert(a):
      b=20
      a=a+b

convert(10)
print(a)

Select the correct output from the given options:

Options

• 10

• 20

• 30

• Error

Answer 1

20

Explanation:

The convert function changes the local variable 'a' value, which serves as the function's formal parameter. The printed value is the global variable 'a' value, which remains unchanged at 20.
