Strip Comments

Complete the solution so that it strips all text that follows any of a set of comment markers passed in. Any whitespace at the end of the line should also be stripped out.

Example

Given an input string of :

apples, pears # and bananas
grapes
bananas !apples

The output expected would be :

apples, pears
grapes
bananas

The code would be called like so :

result = solution("apples, pears # and bananas\ngrapes\nbananas !apples", ["#", "!"])
# result should == "apples, pears\ngrapes\nbananas"

Given Code

def solution(string,markers):
    pass

Solution 1

def solution(string,markers):
    s_list = string.split("\n")
    n_list = []

    for item in s_list:
        s = ""
        for char in item:
            if char in markers:
                break
            else:
                s = s + char
        n_list.append(s.strip())
    return "\n".join(n_list)

---

Solution 2

def solution(string,markers):
    s_list = string.split('\n')
    for marker in markers:
        s_list = [item.split(marker)[0].strip() for item in s_list]
    return '\n'.join(s_list)
