Python program to find number of local variables in a function

Last Updated : 10 Jan, 2019

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:

Python3

# Implementation of above approach

# A function containing 3 variables 
def fun():
    a = 1
    str = 'GeeksForGeeks'


# Driver program
print(fun.__code__.co_nlocals)

Output:

Code #2:

Python3

# 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:

Accessing Python Function Variable Outside the Function

In Python, function variables have local scope and cannot be accessed directly from outside. However, their values can still be retrieved indirectly. For example, if a function defines var = 42, it remains inaccessible externally unless retrieved indirectly.Returning the VariableThe most efficient w
