Python - 相当于 Matlab/Octave 键盘功能？

Question

there is a function keyboard in Matlab/Octave that stops execution and gives control to the keyboard.

It would be useful thing to have around when I have a long running script and need to test a few things. Since Python is interpreted language I guess it should be possible.

Is there such a thing in Python or I should use something more 'Pythonic'? :)

Answer 1

Since Python 3.7 you can use built-in breakpoint() function, as described in PEP 553 . In previous Python versions you would use import pdb; pdb.set_trace() import pdb; pdb.set_trace() as the accepted answer states.

Answer 2

You can use a debugger, such as pdb or ipdb. Once you've acquired the module, just add the following line to your code where you want to stop it:

import ipdb; ipdb.set_trace()

You can use these commands to move through the code once you have control.

Answer 3

If you're not using an IDE, use the Python Debugger . If you are using an IDE, use your IDE's debugger.

Answer 4

import code
code.interact(local=locals())

Returns IDE command prompt just like keyboard in MATLAB, whereas pdb seems to be more focused on stepping through breakpoints in the code (although I haven't used pdb much so haven't dived into much of the functionality)
