Typecasting in python is the process of converting a value from one data type to another data type. In Python, typecasting is performed using built-in functions such as int(), float(), and str().
For example, let’s say you have a variable x that contains the value 10. If you want to convert the value of x to a float, you can use the float() function like this:
x = 10 x = float(x)
You can also use float() to convert a string representation of a number into a float. For example:
x = "10.5" x = float(x)
To convert a value to an integer, you can use the int() function. For example:
x = 10.5 x = int(x)
You can also use int() to convert a string representation of an integer into an integer data type. For example:
x = "10" x = int(x)
To convert a value to a string, you can use the str() function. For example:
x = 10 x = str(x)
It’s important to note that typecasting can only be performed on compatible data types. For example, you can’t use int() to convert a string that contains letters into an integer.
x = "hello" x = int(x) # this will cause an error
Typecasting is a useful tool for converting data types in Python, and it’s something that you’ll likely use frequently in your programming projects.
