Given a Python program, task is to find the number of local variables present in a function.
Examples:
Input : a = 1
b = 2.1
str = 'GeeksForGeeks'
Output : 3
We can use the co_nlocals() function which returns the number of local variables used by the function to get the desired result.
Code #1:
# Implementation of above approach # A function containing 3 variables def fun(): a = 1 str = 'GeeksForGeeks' # Driver program print(fun.__code__.co_nlocals) |
Output:
2
Code #2:
# Python program to find number of # local variables in a function # A function containing no variables def geek(): pass # A function containing 3 variables def fun(): a, b, c = 1, 2.25, 333 str = 'GeeksForGeeks' # Driver program print(geek.__code__.co_nlocals) print(fun.__code__.co_nlocals) |
Output:
0 4
