Print statement considered harmful

Switch from print to debugger() and never look back.

import debug

debugger() # <-- breaks here

Import this module in your main file to add debugger as a builtin command.

Documentation

All functions

debugger()
debugger.enable()
debugger.disable()
debug.wrap(function)
debug.sample(function)
function.samples

Calling debugger opens the ipdb debugger,

import debug

debugger() # <-- breaks here

Calling debugger.disable from the ipdb prompt disables all breakpoints,

import debug

debugger() # <-- breaks here

# >> debugger.disable()
# >> continue

debugger() # <-- does not break here

Using debug.wrap sets a function breakpoint,

def fun():
    pass

def example():
    fun()

fun = debug.wrap(fun)
example() # <-- breaks above at definition of fun

Using debug.sample collects function arguments,

def fun(a, b=None):
    return

fun = debug.sample(fun)
fun(23)
fun(42, 'hello worlds')

debugger() # <-- breaks here

# >> len(fun.samples)
# 2
# >> fun.samples
# [{0: 23, '$': 529}, {0: 42, 'b': 'hello worlds', '$': 1764}]
