In python local variables are those which are defined inside a function and its scope is limited to that function only whereas global variables are those which are not defined inside any function and have a global scope.
We can say that global variables are accessible throughout the program and inside every function whereas local variables are accessible only inside the function in which it was initialized.

Local Variables

Inside function local variables are those which are initialized and belongs only to that particular function.
Then it cannot be accessed anywhere outside the function.

Sample Code

def f():
     
    # local variable
    s = "I love Wikitechy"
    print(s)
 
# Driver code
f()

Output

Global Variables

Outside any function the global variables are those which are defined and which are accessible throughout the program.

Sample Code

# This function uses global variable s
def f():
    print("Inside Function", s)
 
# Global scope
s = "I love Wikitechy"
f()
print("Outside Function", s)

Output
