Casting in Python

Casting in Python has quite a few practical applications. Here's what you need to know about casting in Python .

Define variable type

Sometimes you may want to specify a type for a variable. This can be done by casting or casting in Python.

Python is an object-oriented language, so it uses classes to define data types, including its 'primitive' types.

Casting in Python is done using constructors:

1. Int()- Constructs an integer from an integer, a float character (by removing all decimals) or a string literal (providing the string representation of an integer).
2. Float()- Construct a float from an integer, a float, or a string literal (provide the string representation of a float or an integer)
3. Str()- Build a string from a range of data types, including string, integer string, and float character string.

For example:

Integer:

x = int(1) # x sẽ là 1 y = int(2.8) # y sẽ là 2 z = int("3") # z sẽ là 3

Float:

x = str("s1") # x sẽ là 's1' y = str(2) # y sẽ là '2' z = str(3.0) # z sẽ là '3.0'
