Disemvowel Trolls

Instructions
Trolls are attacking your comment section!

A common way to deal with this situation is to remove all of the vowels from the trolls' comments, neutralizing the threat.

Your task is to write a function that takes a string and return a new string with all vowels removed.

For example, the string "This website is for losers LOL!" would become "Ths wbst s fr lsrs LL!".

Note: for this kata y isn't considered a vowel.
Solution

def disemvowel(string):
    return "".join(c for c in string if c.lower() not in "aeiou")

join() 是一个字符串方法，它用于将序列中的元素连接成一个字符串。该方法接受一个参数，即要连接的序列，然后返回一个新的字符串。
例如，如果我们有一个包含三个字符串的列表 words = ['one', 'two', 'three']，我们可以使用 join() 方法将这些单词连接起来，如下所示：
separator = ' '
result = separator. Join(words)
print(result)
这段代码会输出 "one two three"。
注意，在这个例子中，我们使用空格作为分隔符来连接单词。你可以使用任何字符串作为分隔符。
