Python Casting

Python Casting

Specify a Variable Type

There may be times when you want to specify a type on to a variable. This can be done with casting. Python is an object-orientated language, and as such it uses classes to define data types, including its primitive types.

Casting in python is therefore done using constructor functions:

  • int() – constructs an integer number from an integer literal, a float literal (by removing all decimals), or a string literal (providing the string represents a whole number)
  • float() – constructs a float number from an integer literal, a float literal or a string literal (providing the string represents a float or an integer)
  • str() – constructs a string from a wide variety of data types, including strings, integer literals and float literals
