ListSconsists of 10 consecutive odd integers, and listTconsists of 5 consecutive even integers. If the least integer inSis 7 more than the least integer inT, how much greater is the average (arithmetic mean) of the integers inSthan the average of the integers inT?
Then S has : 9,11,13,15,17,19,21,23,25,27Now If we find the average of List T is 6...
if n is an odd number, then the numbers n and n + 2 are grouped under the category of consecutive odd numbers. They always have a difference of 2 between them and are consecutive in nature, hence the name consecutive odd numbers. For example 3 and 5, 11 and 13, 25...

It is common for us to add up a range of numbers by using the SUM function, but sometimes, we need to sum the largest or smallest 3, 10 or n numbers in a range, this may be a complicated task. Today I introduce you some formulas to solve this problem. ...
We have a list of elements, which are integers and strings. We create two new lists; one having only integers and one only strings. b = [e for e in a if type(e) == int] Here we create a listb, which will contain only integer values. Thetypefunction is used to determine the ty...
