Question

我正在尝试用英语单词（有点像翻译）替换文本文件中的单词。但是，出现错误 builtins.NameError：未定义名称'contents'。如果您需要知道，文本文件是一个字符串列表（中文），用逗号分隔（我需要用英文字符串替换）。

def translate():
    contents = ""
    deleteWords = ["hop", "job"]
    replaceWords = {"T波改变": "T-wave", "窦性心律不齐":"sinus arrhythmia"}

    with open("sample.txt") as diagnosis:
        contents = diagnosis.read()
    for key, value in replaceWords.iteritems():
        contents = contents.replace(key, value)
    return contents
print(contents)

Answer 1

您在函数内部声明了function toogleView(){ $('.menu-toggle').click(function(){ $('.menu-toggle').trigger('active'); $('nav').trigger('active'); }); }，因此它的作用域是此函数，不能在函数外部访问。

尝试：用contents代替print(translate())

Answer 2

contents是一个私有变量，仅在函数内部可用，并在函数完成后立即回收。您需要调用该函数并保存其值。

def translate():
    contents = ""
    #deleteWords = ["hop", "job"]  # This variable is unused so commented out. Delete this line
    replaceWords = {"T波改变": "T-wave", "窦性心律不齐":"sinus arrhythmia"}

    with open("sample.txt") as diagnosis:
        contents = diagnosis.read()
    for key, value in replaceWords.iteritems():
        contents = contents.replace(key, value)
    return contents

# Here contents is a different variable with the same value
contents = translate()  # <== Added this line to make it work
print(contents)
