Python-仅运行一行代码，而不运行脚本中的其余多行

Question

In - Python, inside the the IDLE, in the File Editor Window,

How do you run just a selected single line of code in the script, without having the rest of the lines of the program being runned ?

Answer 1

You'll have to run your line of code form command line:

With the -c (command) argument (assuming your file is named foo.py):

$ python -c 'import foo; print foo.hello()'

Answer 2

You can select and copy a single statement in an Idle editor (or anywhere else, for that matter), switch to the Idle Shell, and paste on the line with the >>> prompt as the bottom. (You can hit to get a clean prompt.) Then hit return just as it you had entered into the shell directly. This works for multiline statements. Being able to do this with a menu selection, hotkey, or right-click selection is on my todo list, as you are not the first to ask about this.

Answer 3

Basically, what we call "debugger" should be fulfilled your requirement. Many IDEs are provided "debugger tools" including IDLE . To use a debugger tool you can just simply

1. add break lines (any lines of code you want a program to stop while program is running),
2. explore your variables (when program is stop you can print out values of your variables at that time)
3. Click/type step to go to the next breakpoint.

This is just a roughly procedure that should be fit to your requirement.
