Explanation: Basically if the number of items in the list is odd, return the middle number, otherwise, if you half an even list, python automatically rounds the higher number so we know the number before that will be one less (since we sorted it) and we can add the default higher numbe...

Python median(): With the Python statistics module, you can find the median, or middle value, of a data set. The Python median() function allows you to calculate the median of any data set without first sorting the list. When you’re working with numbers in Python, you may want to ca...

Let's take a look at how we can use Python to calculate the median. Finding the Median With Python To find the median, we first need to sort the values in our sample. We can achieve that using the built-in sorted() function. sorted() takes an iterable and returns a sorted list con...
The 4th and 5th values in the ordered list is40and42, so the median is themeanof these two values. That is, the sum of those two values divided by 2: Note:It is important that the numbers are ordered before you can find the median. ...
