Question

我试图将不正确的单词附加到列表中，但是当我在函数外部打印列表时，该列表为空，而当我在函数内部打印列表时，它将为每个单词打印一个列表。如何在程序末尾使用不正确的单词将列表打印一次？

文件1：这是我的拼写检查程序

文件2：dis是我的spll cheker程序

因此，应该在列表中添加3个错误的单词

word_list = []

if cmdlength != 2:
    print ("Usage error, expected 2 args got " + str(cmdlength))
    exit()
else:
    try:
        f = open(sys.argv[1])
        f.close()
    except FileNotFoundError:
        print("File does not exist")
        exit()
    try:
        ff = open(sys.argv[2])
        ff.close()
    except FileNotFoundError:
        print("File does not exist")
        exit()
    word = ""
    with open(sys.argv[1],"r") as fh:
        while True:
            ch=fh.read(1)
            if ch == " " or ch == "\n" or ch == ":" or ch == ".":
                with open(sys.argv[2],"r") as fh2:
                    def check_word(word,fh2,word_list):
                        lines = fh2.readlines()
                        for line in lines:
                            x= re.search(word,line)
                            if x:
                                #correctwords
                                print(word + ": " + "0")
                                #count += 1
                            else:
                                #incorrect words
                                print(word, ": " , "1")
                                word_list.append(word)
                                #count2 += 1
                    check_word(word,fh2,word_list)
                word = ''
            else:
                word += ch
            if not ch:
                print(word)
                print("End of file")
                print(word_list)
                break

Answer 1

该函数缺少return语句来返回word_list。这应该起作用

...
def check_word(word,fh2,word_list):
    lines = fh2.readlines()
    for line in lines:
        ...
        word_list.append(word)
        #count2 += 1
    return word_list

word_list = check_word(word,fh2,word_list)

将单词追加到列表
