When to Use a List Comprehension in Python In this quiz, you'll test your understanding of Python list comprehensions. You'll revisit how to rewrite loops as list comprehensions, how to choose between comprehensions and loops, and how to use conditional logic in your comprehensions.Transforming...

If you want to have a key that points to multiple values, you’d use a structure like a list, a tuple, or even another dictionary as the value. (More about this shortly.) Values in dictionaries Values in dictionaries can be any Python object at all. Here are some examples of values:...

They are used to access the elements in an array. As we have noticed, we can treat arrays as Lists but cannot constrain the data type in a list as it is done in an array. This will be understood much more in the next section. Python Built-in Array Module There are many other ...
