Configparser 和带有 % 的字符串

Question

Stupid question with (for sure) simple answer...

I am using configparser to read some strings from a file. When the string has the '%' symbol ($%& for example) it complains:

ConfigParser.InterpolationSyntaxError: '%' must be followed by '%' or '(', found: "%&'"

Anybody familiar with this?

Thanks!

Answer 1

如果您不想替换环境变量，请使用 RawConfigParser，而不是 ConfigParser。

Answer 2

Write two % :

V = ('%%', 'MHz', 'GHz')

result:

('%', 'MHz', 'GHz')

Answer 3

In newer Python versions, use

configParser = configparser.ConfigParser(interpolation=None)

This disables interpolation.

Note that RawConfigParser is a legacy variant. From the python docs :

Consider using ConfigParser instead which checks types of the values to be stored internally. If you don't want interpolation, you can use ConfigParser(interpolation=None).
