解析文本文件中的键值对 [英] Parse key value pairs in a text file

问题描述

我是Python的新手，我搜索如何解析.txt文件. 我的.txt文件是一个包含诸如以下信息的列表:

I am a newbie with Python and I search how to parse a .txt file. My .txt file is a namelist with computation informations like :

myfile.txt

var0 = 16
var1 = 1.12434E10
var2 = -1.923E-3
var3 = 920

var0 = 16
var1 = 1.12434E10
var2 = -1.923E-3
var3 = 920

如何读取值并将其放在python的myvar0, myvar1, myvar2, myvar3中?

How to read the values and put them in myvar0, myvar1, myvar2, myvar3 in python?

推荐答案

我建议将值存储在字典中，而不是存储在单独的局部变量中:

I suggest storing the values in a dictionary instead of in separate local variables:

myvars = {}
with open("namelist.txt") as myfile:
    for line in myfile:
        name, var = line.partition("=")[::2]
        myvars[name.strip()] = float(var)

现在以myvars["var1"]的身份访问它们.如果名称都是有效的python变量名称，则可以将其放在下面:

Now access them as myvars["var1"]. If the names are all valid python variable names, you can put this below:

names = type("Names", [object], myvars)

并例如访问值names.var1.
