问题描述:
Write a python function to print positive numbers in a list.

测试用例:
['assert pos_nos([-1,-2,1,2]) == 1,2', 'assert pos_nos([3,4,-5]) == 3,4', 'assert pos_nos([-2,-3,1]) == 1']

生成的代码:
def pos_nos(numbers):
    positive_numbers = []
    for number in numbers:
        if number > 0:
            positive_numbers.append(number)
    print(','.join(map(str, positive_numbers)))
