How do i print only the count of the positive numbers in an input?-CodePudding

In my code, i want to only count the positive numbers from a user input and print it. So far i can print only the positive numbers but i couldn't print how many positive numbers there are

my code:

num = map(float, input().split())
for post in num:
    if post > 0:
        print(int(post))

input:

2 -4 3.6 1

Output:

2
3
1

the output i want:

3 (the number of positive numbers)(regardless of decimals)

any advice? I've tried getting the length of 'post' but it returns an error.

CodePudding user response：

You can just use the following code.

print(len([i for i in num if i > 0]))

How it works

The above method uses list comprehension, which is equivalent to:

result = []

for i in num:
    if i > 0:
        result.append(i)

print(len(result))

The list result that we get is the list of positive numbers.

>>> print(result)
[2, 3.6, 1]

And then we will use len to count the number of elements in the list.
