Can you explain what the int data type in Python represents and what it is used for?

In Python, the int data type represents an integer of arbitrary length. This means that a variable of type int can store both small and very large integers without overflow.

Main features of int:

• Supports negative and positive values, including zero.
• Unlike some languages, Python automatically extends the size of int as needed.
• Used for storing and performing arithmetic operations with integers.

Example usage:

x = 42
print(type(x))  # <class 'int'>

# Arithmetic operations
result = x * 10 + 5
print(result)  # 425

# Very large number
big_num = 10**100
print(big_num)

int is widely used for counters, indices, arithmetic, bit operations, and many other tasks requiring integer values.
