从配置文件Python读取值 [英] Read Value from Config File Python

问题描述

我有一个文件 .env 文件包含5行

I have a file .env file contain 5 lines

DB_HOST=http://localhost/
DB_DATABASE=bheng-local
DB_USERNAME=root
DB_PASSWORD=1234567890
UNIX_SOCKET=/tmp/mysql.sock

我想编写python来获取 DB_DATABASE 的值我想要这个 bheng-local

I want to write python to grab the value of DB_DATABASE I want this bheng-local

我会用

import linecache
print linecache.getline('.env', 2)

但是有些人可能会更改cofig的顺序，这就是为什么行缓存不是我的选择.

But some people might change the order of the cofigs, that's why linecache is not my option.

我不确定如何只检查某些字符串匹配但要检查整行，并在 = 之后获取值.

I am not sure how to check for only some strings match but all the entire line, and grab the value after the =.

我有点卡在这里:

file = open('.env', "r")
read = file.read()
my_line = ""

for line in read.splitlines():
    if line == "DB_DATABASE=":
        my_line = line
        break
print my_line

有人可以在这里给我一点推动力吗?

Can someone please give me a little push here ?
