Just stumbled upon changing a Python list **in place** with list comprehension:

somelist[:] = [elem for elem in somelist if myPredicate(elem)]

Note the peculiar left-hand side of the assignment. Nice.😀

What am I missing? 🤷‍♀️

Now I am wondering does it work with '.extend' though? 🤔 I guess not because you are looping thru iterables.

Python: List Comprehensions

Comprehensions are an extremely powerful part of Python. But what are they and how can they help me? As you code, you'll notice that certain patterns happen over and over again. Looping through some iterable and create a list is extremely common. Pyt...

JavaScript tip💡

Stop using "forEach" or "for" loops to loop through an array's items

Instead, start using "map" like in this example
