OS : macOS Monterey 12.4 but someone had same issue with Ubuntu
EDI : Thonny
Installation : by pip3 command to use my already installed Python interpreter 3.9
In the Thonny console:
help(print)
no output but python seems waiting for something as with the input function, I press return and:
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/tkinter/__init__.py", line 1892, in __call__

if msg.event_type == "ProgramOutput":

Any idea?

Bug fixed in Thonny v4.0.1 see: https://github.com/thonny/thonny/releases/tag/v4.0.1
The help function works on -objects-, which may not be clear to all.
In your case, you want help on the object that is the built-in ‘print’ function.
You get the results you are looking for by entering
help(‘print()’)
PS: This works for instances like help(‘while’)
Here’s the output for help on print():
Help on built-in function print in module builtins:
print(…)
print(value, …, sep=’ ‘, end=’n’, file=sys.stdout, flush=False)
