简单Python 文件I/O 拼写检查程序

Question

对于 class 我必须创建一个简单的拼写检查程序，它将两个文件作为输入，一个包含正确拼写的单词，另一个包含包含一些拼写错误单词的段落。我以为我已经弄清楚了，但我遇到了一个我以前从未见过的错误。当程序完成时，它会给出错误：

<function check_words at 0x7f99ba6c60d0>

我从来没有见过这个，也不知道它是什么意思，如果能帮助这个程序正常工作，我们将不胜感激。程序代码如下：

import os
def main():
    while True:
        dpath = input("Please enter the path to your dictionary:")
        fpath = input("Please enter the path to the file to spell check:")
        d = os.path.isfile(dpath)
        f = os.path.isfile(fpath)

        if d == True and f == True:
            check_words(dpath, fpath)
            break

    print("The following words were misspelled:")
    print(check_words)

def linecheck(word, dlist):
    if word in dlist:
        return None
    else:
        return word

def check_words(dictionary, file_to_check):
    d = dictionary
    f = file_to_check
    dlist = {}  
    wrong = []  


    with open(d, 'r') as c:
        for line in c:
            (key) = line.strip()
            dlist[key] = ''

    with open(f, 'r') as i:
        for line in i:
            line = line.strip()
            fun = linecheck(line, dlist)
            if fun is not None:
                wrong.append(fun)

    return wrong

if __name__ == '__main__':
    main()

Answer 1

这不是错误，它完全按照您的指示执行。

这一行：

print(check_words)

你是在告诉它打印一个函数。您看到的输出只是 Python 打印函数的名称及其地址："printing the function".

Answer 2

是的，不做 print(check_words)，做 print(check_words())

此外，将check_words(dpath, fpath)更改为misspelled_words = check_words(dpath, fpath)

并将print(check_words)更改为print(misspelled_words)

最终代码（稍作修改）：

import os
def main():
    while True:
        dpath = input("Please enter the path to your dictionary: ")
        fpath = input("Please enter the path to the file to spell check: ")
        d = os.path.isfile(dpath)
        f = os.path.isfile(fpath)

        if d == True and f == True:
            misspelled_words = check_words(dpath, fpath)
            break

    print("\nThe following words were misspelled:\n----------")
    #print(misspelled_words) #comment out this line if you are using the code below

    #optional, if you want a better looking output

    for word in misspelled_words:   # erase these lines if you don't want to use them
        print(word)                 # erase these lines if you don't want to use them

    #------------------------ 


def linecheck(word, dlist):
    if word in dlist:
        return None
    else:
        return word

def check_words(dictionary, file_to_check):
    d = dictionary
    f = file_to_check
    dlist = {}  
    wrong = []  


    with open(d, 'r') as c:
        for line in c:
            (key) = line.strip()
            dlist[key] = ''

    with open(f, 'r') as i:
        for line in i:
            line = line.strip()
            fun = linecheck(line, dlist)
            if fun is not None:
                wrong.append(fun)

    return wrong

if __name__ == '__main__':
    main()
