搜索文本文件并查找用值替换字典键

Question

我正试图把一个程序放在一起，将搜索整个文本文件的内容。该程序将根据字典搜索文本文件，并用字典值替换找到的任何键。我遇到了一个错误，我不知道如何继续。

示例:dictionary={key1:value1,key2:value2,key3:value3等...}

随机文本示例：在事实所有Key1之前，告诉这个任何他的。Key1坚持限制婚礼，Key2返回Key3辩论呈现。

以上事实所有的价值1告诉这个任何他的。值%1坚持限制婚礼值%2返回值%3正在辩论。

mappings = {

Answer 1

您应该使用代码中更正的这一部分：

......
for i in mapping.keys():
    if str(i) in line:
        ......
