number of values in a list greater than a certain number

Question

I have a list of numbers and I want to get the number of times a number appears in a list that meets a certain criteria. I can use a list comprehension (or a list comprehension in a function) but I am wondering if someone has a shorter way.

# list of numbers j=[4,5,6,7,1,3,7,5] #list comprehension of values of j > 5 x = [i for i in j if i>5] #value of x len(x)  #or function version def length_of_list(list_of_numbers, number):      x = [i for i in list_of_numbers if j > number]      return len(x) length_of_list(j, 5) 

is there an even more condensed version?

Answer 1

You could do something like this:

>>> j = [4, 5, 6, 7, 1, 3, 7, 5] >>> sum(i > 5 for i in j) 3 

It might initially seem strange to add True to True this way, but I don't think it's unpythonic; after all, bool is a subclass of int in all versions since 2.3:

>>> issubclass(bool, int) True
