Basically what you want is the amount of times something occurs in the list, which you can do by saying ar.count (num). You can easily do this without ternary operators like so: ar = [1,2,3,2] seen_dict = { num:ar.count (num) for num in ar} print (seen_dict)# {1:1, 2:2, 3:1} This is extremely inefficient (a property common to most …Apr 12, 2022 · The main use case of the symbol @ in Python are decorators.
