The 1 Line of Code Every Python Developer Should Know
tl;dr: print(*dir(my_obj), sep='\n')
Speed up your Python learning with this useful Python one liner 🙂.
Learn how to quickly explore Python objects / modules / datatypes / etc. with this useful 1 liner to get a feel for how an object / package works and what it's capable of.
I came up with this (I mean, likely someone else did too) while reading the Fluent Python book where he was talking about unpacking using the * command.
It works like this:
If you have a list of items, like
my_list = [1, 2, 3]
You could print the whole list like
print(my_list)
Or you could add each item as a separate arg like this:
print(my_list[0], my_list[1], my_list[2])
Or, even shorter:
print(*mylist)
It's the same functionality that lets you assign different variables, like:
a, b, c = [1, 2, 3]
Pretty useful, neat, and good for readability 🙂.
