Write a function called median which takes a list of numbers x and returns the median value (see Wikipedia:Median). If the length of the list x is odd then the median is the middle value and if the length is even then the median is the average of the two middle values. For example, the median of [1,3,1,6,2] is 2 and the median of [1,3,2,6,1,0] is 1.5. Use the built-in function to sort the list of values. Use the modulo operator % to determine if an integer is odd or even. This is an exercise in pure Python. Do not use any Python packages such as or or for this exercise
