Vaiables in python

Python variables are like containers that store values in a program. When you create a variable, Python sets aside some space in memory to hold the value. The type of value you store (like number, text, or decimal) decides how much space is needed. So, using different data types, variables can store things like whole numbers, decimal numbers, or text.

In Python, variables are used to store data values. You don't need to declare the variable type.

Example 1: Basic Variable Assignment

x = 5
y = 'Hello'
print(x)
print(y)

Output:

5
Hello

Assigns integer and string values to variables and prints them.

Example 2: Multiple Assignment

a, b, c = 1, 2, 3
print(a, b, c)

Output:

1 2 3

Assigns multiple variables in one line.

Example 3: Variable Types

x = 10         # int
y = 10.5       # float
z = "Python"  # str
print(type(x), type(y), type(z))

Output:

<class 'int'> <class 'float'> <class 'str'>

Prints the data types of different variables.

Example 4: Type Casting

a = int('10')
b = float('5.5')
c = str(100)
print(a, b, c)

Output:

10 5.5 100

Casts string to int and float, int to string.

Example 5: Global and Local Variables

x = 'global'

def myFunc():
  x = 'local'
  print('Inside:', x)

myFunc()
print('Outside:', x)

Output:

Inside: local
Outside: global

Shows the difference between global and local variables.
