一道4kyu的题。 思路就是 先分行，对每行挨着去注释，然后rstrip，join一下，属于基础题。
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”
from functools import reduce
def solution(code,lst):
return '\n'.join([reduce(lambda m,n:m.split(n)[0],lst,line).strip() for line in code.split('\n') ])
