生成包含10个不同字母的随机单词。
单词长度: 10
Here's a possible solution:
    
    import random
    import string
    
    letters = string.ascii_lowercase
    word = ''.join(random.sample(letters, 10))
    print(word)
    
This code uses the `random.sample()` function to randomly select 10 distinct letters from the lowercase alphabet, and then joins them into a single string. The resulting word has length 10 and contains 10 different letters.
