Python Type Casting

Type casting, also known as type conversion, is the process of changing the data type of a value or variable from one type to another. Python provides built-in functions for performing type casting operations. Let's explore some common type casting functions and examples.

1. int()

The int() function is used to convert a value or variable to an integer data type.

Example:

    x = 5.7
y = int(x)
  

In the above example, the value of x is initially a float. By using the int() function, we cast it to an integer and assign the result to the variable y. The value of y will be 5.

2. float()

The float() function is used to convert a value or variable to a float data type.

Example:

    x = 10
y = float(x)
  

In the above example, the value of x is initially an integer. By using the float() function, we cast it to a float and assign the result to the variable y. The value of y will be 10.0.

3. str()

The str() function is used to convert a value or variable to a string data type.

Example:

    x = 100
y = str(x)
  

In the above example, the value of x is initially an integer. By using the str() function, we cast it to a string and assign the result to the variable y. The value of y will be "100".

4. bool()

The bool() function is used to convert a value or variable to a boolean data type.

Example:

    x = 0
y = bool(x)
  

In the above example, the value of x is initially an integer. By using the bool() function, we cast it to a boolean and assign the result to the variable y. The value of y will be False since the integer value 0 is considered as False in boolean context.

Conclusion

Type casting allows you to convert values or variables from one data type to another in Python. By utilizing the appropriate type casting functions, you can ensure data compatibility and perform necessary operations on different data types.
