我有一个包含字典中所有单词的csv，我想有一个函数，可以指定三个字符，搜索csv中按给定顺序包含给定字符的所有单词。

def read_words(registro):
    with open(file, encoding="utf-8") as f:
        lector = csv.reader(f)
        palabras = [p for p in lector]
    return palabras

file= ("Diccionario.csv")

register = read_words(file)

def search_for_words_with(register, a, b, c):
    res = []
    for w in register:
        if a in w:
            if b in w:
                if c in w:
                    res.append(w)
    return res
