Python is an interpreted language. To create and run code the two basic requirements are:
1: A Text Editor: Python code can be created and edited in most text editors, including freely available applications such as notepad.
2: An Interpreter: That code then has to be interpreted so that it can be submitted for processing by the computer's processing unit.

One method for getting access to these requirements is from the download page at python.org That will set you up to use the IDE (Integrated Development Environment), which is curiously called IDLE in Python. IDLE allows the user directly type python code into its interactive mode (idea for testing small code snippets) and to use its inbuilt text editor for creating python files. These files than can then be run in that interactive mode.
