Thanks to the promotion of large companies such as Google, YouTube, etc.pythonProgramming languages are becoming more and more popular and many programming enthusiasts, too, have made Python their first programming language.
Today we'll talk about the first step in the learning process, installing thePython idle editor, and also its debugging and use.
As a first step, let's go ahead and download a Python idle program installer.
This section is about windows idle, Linux idle is not available, you can directly use the corresponding python interpreter, let's open. Python's official website, find the Downloads section, click on it, and find the appropriate version of the installer.
Since this blogger's system is Window10 64-bit, choose (WindowsX86-64web-based installer)idle python version to download.
Step 2: Find the Python program installation package you just downloaded, double-click it to open it and run the installer.
Generally there is no need to set up too much, directly click on the next step, until the installation is successful, click Finish. If you want to switch the installation directory, you can change the installation path in that step.
Step 3: After the installation is complete, in our start menu, find Python idle and double-click run to debug our python code in our idle. In the start menu, select idle (Python 3.7 64-bit), which is also a GUI program written in Python, and a few other options for Python's module documentation and help.

II. IDLE Operation and Configuration Usage
Click Options->Configure IDLE in turn, and you can set fonts, syntax highlighting, and shortcuts in the Settings page.
I've chosen the equal-width Consolas font here for the code to look nice.
It is recommended to choose equal width fonts, it is easy to recognize the number 0 and capital letter O, the number 1 and the letter l (lowercase letter L), I (capital letter i). The visual effect is good, if you don't know which is the equal width font, please consult your mother, if your eyes are not good, you can change the size of the font. Click OK or Apply will take effect immediately.
III. IDLE Debugging
In the Python Shell window, click the "Debugger" menu item in the "Debug" menu to launch IDLE's interactive Debugger" menu item in the "Debug" menu in the "Illll" window. IDLE opens the Debug Control window and outputs "[DEBUG ON]" in the Python Shell window followed by a "&&". followed by a ">>>" prompt. We can now use this "Python Shell" window as we normally would, except that any commands we enter are now allowed in the debugger. We can view local and global variables in the "Debug Control" window. If you want to exit the debugger, you can click the "Debugger" menu item in the "Debug" menu again, and IDLE will close the "Debug Control IDLE will close the "Debug Control" window and output "[DEBUG OFF]" in the "Python Shell" window.
