循环丢失迭代

Question

我正在尝试测试我正在迭代的单词是否为大写。如果单词不是大写，也不在字典中，则应按原样打印。如果单词不是大写的，也不在字典中，就应该替换并打印出来。如果单词是大写的，则需要将其设置为小写，以测试它是否在字典中。如果它是大写的，并且在字典中，这个词应该被替换并打印出来。如果它是大写的，并且不在字典中，那么这个词应该再次变成大写并打印出来。

我已经尝试了下面的两个代码，它们似乎在做同样的事情。它不会更改大写字母。它甚至可能没有对它们进行迭代。

def replace_mode(text_list,misspelling):
    update = ''
#loop iterates over the lines and over each word
    for line in text_list:
        word = line.split(' ')
        for key in word:
            if key.isupper():
                key = key.lower()
                if key in misspelling.keys(): #checks if the word is in the dictionary
                    update = misspelling[key]
                    print(update.capitalize(), end=(' '))
                else: 
                    print(key.capitalize(), end=(' '))
            elif key in misspelling.keys():
                update = misspelling[key]
                print(update, end=(' '))
            else:  
                print(key, end=(' '))
        print()

def replace_mode(text_list,misspelling):
    update = ''
#loop iterates over the lines and over each word
    for line in text_list:
        word = line.split(' ')
        for key in word:
            capital = False
            if key.isupper():
                capital = True
                key = key.lower()
            if capital == True:
                if key in misspelling.keys(): #checks if the word is in the dictionary
                    update = misspelling[key]
                    print(update.capitalize(), end=(' '))
                else:
                    print(key.capitalize(), end=(' '))
            if capital == False:
                if key in misspelling.keys():
                    update = misspelling[key]
                    print(update, end=(' '))
                else:
                    print(key, end=(' '))
        print()

你的代码在你的帖子中格式不正确，所以读起来有点困难，但我认为我正在收集你想要做的事情。以下是一些小贴士：

isupper()检查字符串中的所有字符是否都是大写的，但通常情况下，如果只有第一个字母是大写，则认为单词是大写的。

keys()返回一个包含字典键的迭代量，但是检查字典中的成员关系要简单得多：if key in misspelling:将检查key是否是字典misspelling中的键之一

当涉及到bool时，您不必将它们与条件句中的其他bool进行比较；您应该编写if capital，而不是if capital == True:。您可以使用else，而不是检查False条件。

把这些想法放在一起：

    # Is the first letter of this word capitalized?
    capital = key[0].isupper()

    # Is the lowercased version of the word in the dictionary?
    in_dict = key.lower() in misspelling

    if capital and in_dict:
        # Word is capitalized and in the dictionary
        pass  # do something
    elif capital and not in_dict:
        # Word is capitalized and not in the dictionary
        pass  # do something
    elif capital and in_dict:
        # Word is not capitalized and in the dictionary
        pass  # do something
    else:
        # Word is not capitalized and not in the dictionary
        pass  # do something

要更新字典，您必须访问一个键并将其替换为其他人。update = misspelling[key]不这样做；它访问与key对应的值，并将其存储在变量update中。你可能想做的是misspelling[key] = key；或者类似的东西，从你的帖子中看不清字典应该包含什么
