Types of Variable Names in Python ?

 Types of Variable Names: 

•  Camel Case: First letter lowercase, subsequent words capitalized (e.g., myFirstVariable). 
•  Pascal Case: Each word starts with an uppercase letter (e.g., MyFirstVariable). 
•  Snake Case: Words separated by underscores, all lowercase (e.g., my_first_variable). 
• 
  

 Multiple Values to Multiple Variables: 

•  Multiple values can be assigned to multiple variables in one line.

Program:

x, y, z = "cycle", "bike", "car"
print(x)
print(y)
print(z)

Output: 

cycle
bike
car

Assigning one value to multiple variables: 

Program: 

x = y = z = "Python"
print(x)
print(y)
print(z)

Output: 

Python
Python
Python

 Unpack Collection: 

•  Collections like lists can also be unpacked into variables. 

Program: 

Vehicles = ["cycle", "bike", "car"]
x, y, z = Vehicles
print(x)
print(y)
print(z)

Output: 

cycle
bike
car

Global Variables: 

•  Global variables are defined outside of functions and can be accessed inside functions. 
•  Use the global keyword to modify a global variable inside a function. 

Program: 

x = "easy"
def myfunc():
    global x
    print("Python is " + x)
myfunc()

Output: 

Python is easy

Local Variables: 

•  Local variables are defined inside a function and can only be accessed within that function. 

Program: 

def myfunc():
    x = "easy" # Local variable
    print("Python is " + x)
myfunc()

Output: 

Python is easy
