How To Convert String To Number?

Use `int()` to convert a string to an integer

Use `float()` to convert a string to a decimal number

Use `complex()` to convert a string to a complex number

Use `Decimal()` from the `decimal` module for precise decimal conversion

Use `eval()` only when the string is trusted and contains a valid numeric expression

Use `str.isdigit()` to check whether a string contains only digits before converting

Use `try` and `except` to handle conversion errors safely

Use `int(“123”)`

Use `float(“123.45”)`

Use `Decimal(“123.45”)`
