x Simple, given a string of words, return the length of the shortest word(s).
String will never be empty and you do not need to account for different data types.

def find_short(s):
    # your code here
    return l # l: shortest word length

Solution:

def find_short(s):
    word_list = s.split()
    len_list = []
    for word in word_list:
        len_list.append(len(word))
    l = min(len_list)
    return l
