Python 将字符串排序到字典中，其中初始字符是键，值是以该字符开头的所有行的列表

情况：AHLTA，一种电子病历，将GUI模板导出为文本。我正在构建一个模板编辑器，需要导入文本文件。每行表示一个GUI元素，并以一个数字开头，该数字标识GUI中的父选项卡。行的顺序不重要。我正在使用Python 3

示例（文件）：

这似乎是一个恰当的循环，但我最终得到了一个空对：

{3: []}
3: []

摘要：只有在运行时才知道列表的数量，如何创建列表字典

def main():
    # I'm assuming you can get this far...
    lines = [
        '1,some stuff 1',
        '2,some stuff 2,more stuff',
        '2,some stuff 4,candy,bacon',
        '3,some stuff 3,this,is,horrible...'
    ]

    # Something to hold your parsed data
    data = {}

    # Iterate over each line of your file
    for line in lines:

        # Split the data apart on comma per your example data
        parts = line.split(',')

        # denote the key is the first part of the split data
        key = parts[0]
        if key not in data:
            # Since there could be multiple values per key we need to keep a
            # list of mapped values
            data[key] = []

        # put the "other data" into the list
        index_of_sep = line.find(',')
        data[key].append(line[index_of_sep+1:])

    # You probably want to return here. I'm printing so you can see the result
    print(data)


if __name__ == '__main__':
    main()

结果

C:\Python35\python.exe C:/Users/Frito/GitSource/sandbox/sample.py
{'3': ['some stuff 3,this,is,horrible...'], '1': ['some stuff 1'], '2': ['some stuff 2,more stuff', 'some stuff 4,candy,bacon']}

不要写“废话废话”，而是要确保你的问题格式正确，这样我们在阅读时就不会被抓住。你能不能也展示一个输出示例？具体到@cosinepenguine的观点，就是你目前拥有的代码，你得到的成果和你想要的成果对帮助你的社区来说是最有益的：-）为这些废话道歉；浏览器出错，无法预览文本！是否可以删除下一票？这里我有一个字符串形式的键。如果你真的需要它是一个数字类型，这里有很多关于如何做到这一点的答案：-）弗里托，谢谢你。我很惊讶你从早期的发布事故中发现了我想要什么！哈，没问题。很高兴这有帮助！感谢您接受答案：-D
