Pi Pico W: print in server functions called by Pico don't show in console or logs

Anvil Q&A
8

I do this with lots of old code or when I’m starting a not very important project, it is really quite simple as long as you don’t mind your debugger yelling at you.

What I do (in this order in the script) is make a deepcopy of print, (print2 or whatever), then build a wrapper function that does logging code, then the copy of print.

Then you replace the builtin print with your wrapper function.

from copy import deepcopy

print2 = deepcopy(print)

def print_wrapper(*args, **kwargs):
    #do some logging code
    #do some anvil logging code
    example_send_to_anvil_function(*args, **kwargs)
    
    print2(*args, **kwargs)


print = print_wrapper

This is definitely on the “please don’t do this” list of things people do anyway.
