如何读取和存储从文本文件到字典的值。 [蟒蛇] [英] How to read and store values from a text file into a dictionary. [python]

问题描述

我试图找出如何打开一个文件，然后将其内容存储到一个字典中，使用零件号。作为关键和其他信息作为价值。所以我希望它看起来像这样：

I'm trying to figure out how to open up a file and then store it's contents into a dictionary using the Part no. as the key and the other information as the value. So I want it to look something like this:

{Part no.: "Description,Price", 453: "Sperving_Bearing,9900", 1342: "Panametric_Fan,23400",9480: "Converter_Exchange,93859"}

能够将文件中的文本存储到列表中，但是我不知道如何为一个键分配多个值。我试图这样做，而不导入任何模块。我一直在使用基本的str方法，列表方法和dict方法。

I was able to store the text from the file into a list, but I'm not sure how to assign more than one value to a key. I'm trying to do this without importing any modules. I've been using the basic str methods, list methods and dict methods.

推荐答案

对于 txt

For a txt file like so

453     Sperving_Bearing    9900
1342    Panametric_Fan      23400
9480    Converter_Exchange  93859

你可以做

>>> newDict = {}
>>> with open('testFile.txt', 'r') as f:
        for line in f:
            splitLine = line.split()
            newDict[int(splitLine[0])] = ",".join(splitLine[1:])


>>> newDict
{9480: 'Converter_Exchange,93859', 453: 'Sperving_Bearing,9900', 1342: 'Panametric_Fan,23400'}

您可以通过检查 line.startswith（）来删除 ----... '-----'）。

You can get rid of the ----... line by just checking if line.startswith('-----').

编辑 - 如果您确定前两行包含同样的东西，那么你可以做

EDIT - If you are sure that the first two lines contain the same stuff, then you can just do

>>> testDict = {"Part no.": "Description,Price"}
>>> with open('testFile.txt', 'r') as f:
        _ = next(f)
        _ = next(f)
        for line in f:
            splitLine = line.split()
            testDict[int(splitLine[0])] = ",".join(splitLine[1:])       
>>> testDict
{9480: 'Converter_Exchange,93859', 'Part no.': 'Description,Price', 453: 'Sperving_Bearing,9900', 1342: 'Panametric_Fan,23400'}

将第一行添加到代码中的 testDict 中，并跳过前两个行，然后继续正常。

This adds the first line to the testDict in the code and skips the first two lines and then continues on as normal.
