python - My script returns an error when the test isn't corresponding to the Regex: 'NoneType' object has no attribute 'group' -


my script down here supposed return result in format 

[ {'heure':xxxx,'mid': xxxx,'type message': "e.g sms.message ", "origine":xxx,"destination":xxxx}]

well works without type message i've added think regex isn't correct. :/ doesn't work when add data doesn't have looks regex think have try: - except: don't know how. :/ 

#!/usr/bin/env python # -*- coding: utf-8 -*-  import re  ################################_function extract_###############################################   def extraire(data):     ms = re.match(r'(\s+).*mid:(\d+).*(r:nvs:\w+)', data) # heure & mid      k = re.findall(r"/\s+", data ) # source & destination extracte      return {'heure':ms.group(1), 'mid':ms.group(2),'type message':ms.group(3),"origine":k[0],"destination":k[1]}   #################################################################################################  tableau = []   data3 = "12:07:32.546 mta         messages       doc o:tcarval (nvs:smtp/jack.reacher@example.de) r:nvs:voice/+45154245 mid:6500" data4 = "12:07:41.391 mta         messages       rep o:tcarval (nvs:smtp/brad.alison@yow.en) r:nvs:**sms.message**/+39872422 mid:6500" data5 = "12:07:32.546 mta         messages       doc o:tcarval (nvs:voice/+69517412carval@ifremer.no) r:nvs:sms.message/+34659879 mid:6500" data6 = "12:07:32.545 mta     messages   doc o:tcarval example@whitout-slash.com        r:nvs:voice/01020150405 mid:9797" data_list = [ data3, data4,data5, data6] tableau = [extraire(data) data in data_list] print tableau

change extraire function this, trying access properties on ms when there no matches. , when there no matches, ms none :

def extraire(data):     ms = re.match(r'(\s+).*mid:(\d+).*(r:nvs:\w+)', data) # heure & mid                                      print(str(ms))     if(ms not none):         k = re.findall(r"/\s+", data ) # source & destination extracte                                           return {'heure':ms.group(1), 'mid':ms.group(2),'type message':ms.group(3),"origine":k[0],"desti\ nation":k[1]}     else:         return {}

btw, regex not seem match text intend match. may list index out of range error if k not contain number of elements seeking.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
