关于python的一个字典的问题
下面是一段Python的代码

Python code

#-*- coding:utf-8 -*-  scope={}def getsetting(filepath):      f = open(filepath)      for l in f:          scope[l.split('=')[0].strip()]=l.split('=')[1][:-1].strip()          print scope[l.split('=')[0].strip()]      f.close()      print scope['case_no']    if __name__ == '__main__':      getsetting('setting1.ini')  

下面是setting1.ini的文件内容：
case_no = case_no
consignor = consignor
contact = contact
contact_address =contact_address
contact_number = contact_number
delegate_date = delegate_date
case_brief =case_brief
delegate_info = delegate_info
identification_demand = identification_demand
identification_materials = identification_materials
identification_samples = identification_samples

为什么每次都报

Traceback (most recent call last):
File "E:\WorkSpace\Python\template\createfile.py", line 28, in <module>
getsetting('setting1.ini')
File "E:\WorkSpace\Python\template\createfile.py", line 16, in getsetting
print scope['case_no']
KeyError: 'case_no'
的错误。
而其它的键值都没有问题，就只有这个case_no了，改了其它名称也不行。

代码最好不要有文件读写，重现起来麻烦。下面的代码执行无异常：

Python code

x = '''case_no = case_noconsignor = consignorcontact = contactcontact_address =contact_addresscontact_number = contact_numberdelegate_date = delegate_datecase_brief =case_brief delegate_info = delegate_infoidentification_demand = identification_demandidentification_materials = identification_materialsidentification_samples = identification_samples'''scope={}def getsetting():      for l in x.splitlines():        scope[l.split('=')[0].strip()]=l.split('=')[1][:-1].strip()          print scope[l.split('=')[0].strip()]      print scope['case_no']    if __name__ == '__main__':      getsetting()

没有就应该是没有，你print scope看看整个字典先，可能你的ini文件有bom头，简单open()并不会滤掉...
