(1) Development environment introduction
Development environment, English is
IDE
(
Integrated Development Environment
Integrated Development Environment). Don't get hung up on which development environment to use. The development environment is essentially the encapsulation of the Python
interpreter python.exe
, and the core is the same. It can be said:
"
The development environment
IDE
is just a tool for the interpreter", just to make programming more convenient for programmers and reduce error rates, especially spelling mistakes. Currently, the mainstream
development environments are as follows:
1
IDLE
Pycharm (recommended) vscode (recommended) jupyter
(2) Introduction to IDLE
1
IDLE
is
the official standard development environment of
Python , and
IDLE is installed at the same time after Python is installed . IDLE already has almost all the functions of Python development (smart syntax prompts, different colors to display different types, etc.), and does not require other configurations, which is very suitable for beginners.

IDLE
is a simple and compact
IDE built into
the Python
standard distribution
, including basic components such as interactive command lines, editors, and debuggers, which are sufficient for most simple applications.

IDLE
is written in pure
Python
based on
Tkinter
, and the original author is the father of
Python
(Uncle Turtle).
(3) IDLE practical operation
1
Steps: Interactive mode ①Start IDLE, the default is to enter the interactive mode. ② Write and execute Python source files
(4) Creation and execution of Python files
In the interactive environment used earlier, only one statement can be executed at a time; in order to write multiple statements to implement complex logic, we start this chapter by creating a Python
file and executing the file.
In the IDLE
environment, we can
create a Python file through
File
--
> new
, and edit the content of the file. We can also save files through File -- >save/save as . It is generally saved as a file with the extension py . To execute the edited file, you can use the shortcut key F5 or click Run -- >Run module.
(5) PyCharm download and installation
Download address:
https://www.jetbrains.com/pycharm/download
Download the corresponding version:
It is the same as installing ordinary software, just click Next. There are only a few frames that require individual attention.
After the installation is complete, run
pycharm
. Choose not to import configuration:
(6) Create a python project
1
option:
New Project
Select the path (try not to contain Chinese), project name:
(7) Development and operation of the project
After opening the project, right click on the project and create a
Python
file
mypy01
To run the py file, right-click the editing area and select Run mypy01 .
