Type Conversion in Python
In Python, type conversion (also known as type casting) refers to the process of converting one data type into another. Python provides built-in functions to perform type conversion, allowing you to convert variables or values from one data type to another as needed.
There are two types of type conversion in Python:
- Implicit type conversion: This type of conversion is performed automatically by the Python interpreter. For example, if you add an integer and a string, the Python interpreter will automatically convert the string to an integer before performing the addition.
- Explicit type conversion: This type of conversion is performed by the user using the built-in type conversion functions. For example, the int() function can be used to convert a string to an integer.
Here are some common type conversion functions along with examples:
Converts a value to an integer data type.
Converts a value to a floating-point data type.
Converts a value to a string data type.
Converts a value to a Boolean data type.
list(), tuple(), set() functions
Convert a sequence or iterable to a list, tuple, or set, respectively.
Type conversion is essential when you need to perform operations or utilize variables of different data types. It allows you to manipulate and combine data of various types, enhancing the flexibility and versatility of your Python programs. However, be cautious when converting data types, as some conversions may lead to loss of information or unexpected results.
