[issue30760] configparse module in python3 can not write '%' to config file

[Łukasz Langa]

Łukasz Langa added the comment:

With the default ConfigParser, we're using basic interpolation, as covered by:

https://docs.python.org/3/library/configparser.html#configparser.BasicInterpolation

To not have it, set interpolation to None in the ConfigParser constructor:

config = configparser.ConfigParser(interpolation=None)

Then percent signs will be treated like any other character. Let me know if you 
have further questions.

[issue30760] configparse module in python3 can not write '%' to config file

[quanyechavshuo]

New submission from quanyechavshuo:

Hello,I was using configparser module in python3.6,but find it works not good 
when I try to write '%' to my config file,below is my func:

def update_config_file_key_value(file, section, key_name, key_value):
# 通过configparser模块的调用更新配置文件
# section是[]里面的值
if os.path.exists(file) == False:
os.system("touch %s" % file)
import configparser
config = configparser.ConfigParser()
config.read(file)
sectionList = config.sections()
if section not in sectionList:
config.add_section(section)
config.set(section, key_name, str(key_value))
with open(file, 'w') as f:
config.write(f)

When I use it as:
update_config_file_key_value('config.ini','default','cookie',"123")
it works well,but below not ok:
update_config_file_key_value('config.ini','default','cookie',"%123")
and below not ok:
update_config_file_key_value('config.ini','default','cookie',"123%")
and below not ok:
update_config_file_key_value('config.ini','default','cookie',"12%3")

That's to say,configparser can not write '%' to config file.
