Is there single line function which can convert all those dictionaries into deafult. I want that if somekeydon't exist in any of child dict then it don't get key error. EDIT: #something like this , but i was looking for something buildindefconvert_dict(dictionary):forkey,...
I'm looking for a way to find all keys in dict_1 for which one or more value is a key that has a value > 1 in dict_2 and the number of times a value associated with these keys is repeated in dict_2. Once I've found this, I would like to get another ...
We have a list of users. Each user is represented as a dictionary. One of the keys of the dictionary is the date of birth. user_dts = [datetime.strptime(user['date_of_birth'], "%Y-%m-%d") for user in users] With a Python list comprehension, we create a list of user datetime o...

In this tutorial, we'll be covering the any() and all() functions in Python. The any(iterable) and all(iterable) are built-in functions in Python and have been around since Python 2.5 was released. Both functions are equivalent to writing a series of or and and operators respectively bet...

Guido van Rossum proposed the all() and any() functions in an effort to remove functools.reduce() and other functional tools, such as filter() and map(), from Python. However, the Python community wasn’t happy with removing these tools. Even so, all() and any() were added as built...
