Type Conversion in Python

Type conversion (or type casting) changes a value from one data type to another. Python does some conversions automatically (implicit), but often you need to do it explicitly.

This is important when working with user input, calculations, or different data structures.

Implicit Conversion

Python automatically converts types in some operations.

Explicit Conversion

Use built-in functions to convert manually.

To Integer – int()

To Float – float()

To String – str()

To Boolean – bool()

Converting Collections

Common Use Cases

• User input (always string) → convert to number
• Combining numbers and strings for output
• Preparing data for calculations
