Python Casting
Casting in Python is the process of converting one data type to another. Python provides several built-in functions for casting data types, such as int(), float(), str(), list(), tuple(), and dict().
1. Casting to Integer
To convert a value to an integer, you can use the int() function.
Example:
x = int(3.14)
y = int("5")2. Casting to Float
To convert a value to a float, you can use the float() function.
Example:
x = float(5)
y = float("3.14")3. Casting to String
To convert a value to a string, you can use the str() function.
Example:
x = str(10)
y = str(3.14)4. Casting to List
To convert a value to a list, you can use the list() function.
Example:
x = list("hello")
y = list((1, 2, 3))5. Casting to Tuple
To convert a value to a tuple, you can use the tuple() function.
Example:
x = tuple([1, 2, 3])
y = tuple("world")6. Casting to Dictionary
To convert a value to a dictionary, you can use the dict() function.
Example:
x = dict(name="Alice", age=30)
y = dict([('name', 'Bob'), ('age', 25)])Conclusion
Casting allows you to convert data from one type to another in Python. Understanding how to use casting functions is essential for working with different data types and ensuring compatibility in your Python programs.
