How to use Python Global variables, python local variables, python NonLocal Variables, how to use nonlocal variables in python, how to use global variables in python, how to use local variables in python.
In this video, we'll be talking about variables and their scope in Python. We'll be covering the global vs local scope, nonlocal variables, and what the implications are for each.
If you're new to Python, or if you're having trouble understanding variable scope, then this video is for you. By the end of it, you'll know exactly what global vs local variables are, and why they're important. Plus, you'll be better able to understand what the implications are for each type of variable.
A variable scope specifies the region where we can access a variable.
For example,
def showEmployeeDetails():
age = 35
print(age)


showEmployeeDetails()
print(age)


Here, the age variable is created inside the function, so it can only be accessed within it (local scope). This type of variable is called a local variable.
Based on the scope, we can classify Python variables into three types:
1. Local Variables
2. Global Variables
3. Nonlocal Variables
________________________________________
Python Local Variables
When we declare variables inside a function, these variables will have a local scope (within the function). We cannot access them outside the function.
These types of variables are called local variables. For example,


def showEmployeeDetails():
age = 35
print(age)


showEmployeeDetails()
print(age)


Python Global Variables
In Python, a variable declared outside of the function or in global scope is known as a global variable. This means that a global variable can be accessed inside or outside of the function


For Example:
name = "Raj"
def showEmployeeDetailsGlobal1():
print(name)


def showEmployeeDetailsGlobal2():
print(name)


showEmployeeDetailsGlobal1()
print('Global', name)


showEmployeeDetailsGlobal2()
print('Global', name)


Python Nonlocal Variables
In Python, nonlocal variables are used in nested functions whose local scope is not defined. This means that the variable can be neither in the local nor the global scope.
We use the nonlocal keyword to create nonlocal variables.For example,

def showEmployeeDetailsnonLocal():
message = 'local'
# nested function
def inner():


# declare nonlocal variable
nonlocal message


message = 'nonlocal1'
print("inner:", message)


inner()
print("outer:", message)


outer()
---------------------------------------------------
Note : If we change the value of a nonlocal variable, the changes appear in the local variable.
