A dirty decorator for logging the docstrings of methods as they get called.

logdoc.py

from functools import wraps
# sometimes you need to do a bunch of tracing and it is easier to just see docstrings flow by rather than write print statements.
def logdoc(func):
  '''Wraps a function and logs the docstring of that function whenever it is called
  Just decorate the function:
  
  @logdoc
  def foo(bar):
    """prints the bar and returns twice the bar"""
    print(bar)
    return 2*bar
  
  >>> foo(4)
  "prints the bar and returns twice the bar"
  "4"
  8
  '''
  
  @wraps(func)
  def logdoc_wrapper(*args, **kwargs):
    print(func.__doc__)
    return func(*args, **kwargs)
  return logdoc_wrapper
