按照老师写的代码，自己run报错NoSectionError: No section: 'user'，请教怎么解决
报错信息如下：
=================== RESTART: C:/Python27/0506/文件练习.py ===================

Traceback (most recent call last):
File "C:/Python27/0506/文件练习.py", line 43, in <module>

File "C:/Python27/0506/文件练习.py", line 32, in set_item
self.cfg.set(section,key,value)
File "C:\Python27\lib\ConfigParser.py", line 396, in set
raise NoSectionError(section)
NoSectionError: No section: 'userinfo'
imooc.txt内容如下：
[userinfo]
name=zhangsan
pwd=abc
[study]
python_bse=15
python_junior=20
linux_base =15
代码如下
import os
import os.path
import ConfigParser
class student_info(object):
def __init__(self,recordfile):
self.logfile = recordfile
self.cfg = ConfigParser.ConfigParser()
def cfg_load(self):
self.cfg.read(self.logfile)
def cfg_dump(self):
se_list = self.cfg.sections()
print"-------------->"
for se in se_list:
print se
print se_list.items(se)
print"-------------->"
def delete_item(self,section,key):
self.cfg.remove_option(section,key)
def delete_section(self,section):
self.cfg.remove_section(section)
def add_section(self,section):
secl.cfg.add_section(section)
def set_item(self,section,key,value):
self.cfg.set(section,key,value)
def save(self):
fp = open(self.logfile,'w')
self.cfg.write(fp)
fp.close()
if __name__ == '__main__':
info = student_info('imooc.txt')
info.cfg_load()
info.cfg_dump()
info.set_item('userinfo','pwd','abc')
info.cfg_dump()
info.add_section('login')
info.set_item('login','2015-05-11','20')
info.cfg_dum()
info.save()
txt文件里明明有userinfo，求解。
