Python Icecream Module
icecream is a library that makes debugging with print statements sweeter. It prints both the expression/variable name and its value, which is often what you want when debugging.
Installation
pip install icecreamBasic Usage
Import ic from icecream. It works like print, but better.
from icecream import ic
def foo(i):
return i + 333
ic(foo(123))
# Output: ic| foo(123): 456Inspecting Variables
It prints the variable name and value.
d = {'a': 1, 'b': 2}
ic(d['a'])
# Output: ic| d['a']: 1Execution Flow
If you call ic() without arguments, it prints the filename, line number, and parent function. This is great for tracing execution flow.
def my_function():
ic()
my_function()
# Output: ic| script.py:12 in my_function() at 14:30:00.123Configuration
You can configure the output prefix and whether it includes context (filename, line number).
ic.configureOutput(prefix='Debug | ', includeContext=True)
ic('test')
# Output: Debug | script.py:20 in <module>- testDisabling
You can disable icecream in production without removing the import statements.
ic.disable()
ic(1) # No output
ic.enable()
