Why does anyone go to college?

The preponderance of Democrats within American academia has been well-documented for many years. One 2018 survey of the political affiliations of 5,197 PhD-holding professors from top-ranked liberal-arts colleges, for example, found Democrat-to-Republican ratios in the 5-to-1 to 8-to-1 range for such subjects as chemistry, economics, mathematics, physics, and computer science.

Asked 1 year, 6 months ago Viewed 2k times 23 I want to write this code as pythonic. My real array much bigger than this example. ( 5+10+20+3+2 ) / 5 print(np.mean(array,key=lambda x:x[1])) TypeError: mean() got an unexpected keyword argument 'key' array = [('a', 5) , ('b', 10), ('c', 20), ('d', 3), ('e', 2)] sum = 0 for i in range(len(array)): sum = sum + array[i][1] average = sum / len(array) print(average) import numpy as np print(np.mean(array,key=lambda x:x[1])) How can avoid this?
