A list in Python can contain only one data type. For example, a list can only contain integer numbers or text or real numbers. Under no circumstances can it contain a value data type combination.

The following list is probably wrong. Or maybe not;
[3, ‘Cat’, 6/3, 5.6, ‘John’]

By executing the following code:

list = [3, ‘Cat’, 2, 5.6, ‘John’]
list.insert (2, ‘lion’)
print (list)

We will get the result:

Loop is a set of commands that can be repeated.

The range function, when combined with the for function, always indicates the number that the repeating variable counts will end.
