练习：密码生成器

写一个叫做 generate_password 的函数，该函数会从提供的单词文件中随机选择三个单词，并将它们连接成一个字符串。我们已经在起始代码中提供了从文件中读取数据的代码，你需要利用这些部分构建一个密码。

Start Quiz:

password_generator.py words.txt

# Use an import statement at the top

word_file = "words.txt"
word_list = []

#fill up the word_list
with open(word_file,'r') as words:
	for line in words:
		# remove white space and make everything lowercase
		word = line.strip().lower()
		# don't include words that are too long or too short
		if 3 < len(word) < 8:
			word_list.append(word)

# Add your function generate_password here
# It should return a string consisting of three random words 
# concatenated together without spaces



# test your function
print(generate_password())
