Additionally, when you find yourself searching for a matching item in an iterable, in general you may want to question whether you should use a dictionary instead. Cheat sheet: Python'sanyandall Here's a quick cheat sheet for you. This code uses abreakstatement because we're not returning ...
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 objects. With the strptime function, we transform the date_of_birth ...

Write a Python program to multiply all the items in a dictionary. Sample Solution: Python Code: # Create a dictionary 'my_dict' with keys 'data1', 'data2', and 'data3', along with their respective values.my_dict={'data1':100,'data2':-54,'data3':247}# Initialize a variable 're...
The Python any() and all() functions evaluate the items in a list to see which are true. The any() method returns true if any of the list items are true, and the all() function returns true if all the list items are true. Often, when you’re programming, you may want to check...

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...
