As a rule of thumb, do NOT modify a collection / array / list while iterating over it.

For example, this code will NOT print all elements in the list before deleting them. #python #PythonTip

Using #Python pprint to pretty print a nested data structure:

In python, comparison operators can be chained:

>>> x = 3
>>> if 2 < x < 4:

Use tempfile.TemporaryDirectory (#Python Standard Library) to create temporary directories.

In pytest you can use its tmp_path fixture:

In #Python you can group constants using an enum:

A decorator is a function that takes another function and extends its behavior. See an example of repeat_twice decorator 👇

But what about decorators with parameters (repeat_N_times)? Then you need a function returning a function returning a function 🤩

You can use the abstractmethod decorator to force derived classes to implement certain methods:

Use iter to request any number of inputs

for el in iter(input, ""):
print(el)
