Debugging

IceCream is a Python library that makes debugging easier and more efficient. With arguments, ic() inspects itself and prints both arguments and the values. Just give ic() a variable or expression and you are done.

 
from icecream import ic

def sum(x, y):
    return x + y

dict = {'a': 1}

ic(sum(2,3))
ic(dict)

"""
    ic| sum(2,3): 5
    ic| dict: {'a': 1}
"""

Without Arguments

Without argumenst, ic() inspects itself and prints filename, line number and parent function. Jupyter doesn't output a new line with the value automatically, if we add a semicolon.

 
def myfunction():
    ic()
    
    return True
    
myfunction();  # semicolon at the end

"""
    ic| 3877364280.py:2 in myfunction() at 10:24:00.200
"""

Disable Icecream

We can temporary disable ic(), and later re-enable. Icecream continues to return its arguments when disabled, of course.

 
ic(1)

ic.disable()
ic(2)

ic.enable()
ic(3);

"""
    ic| 1
    ic| 3
"""
