Python: Regex and String Length in byte -


i writing program in python , have question (i 100% new python):

import re  rawdata = '7i+8i-7i-9i-8i-'  print len(rawdata)  rawdata = re.sub("[0-9]i\+","",rawdata) rawdata = re.sub("[0-9]i\-","",rawdata)  print rawdata
  1. how merge 2 regex 1 using |? means rid of both 9i- , 9i+ using 1 regex operation.
  2. does len(rawdata) return length of rawdata byte?

thank you.

see difference:

$ python3 python 3.1.3 (r313:86834, may 20 2011, 06:10:42)  [gcc 4.4.5] on linux2 type "help", "copyright", "credits" or "license" more information. >>> len('día')   # unicode text 3 >>>   $ python python 2.7.1 (r271:86832, may 20 2011, 17:19:04)  [gcc 4.4.5] on linux2 type "help", "copyright", "credits" or "license" more information. >>> len('día')   # bytes 4 >>> len(u'día')  # unicode text 3 >>>   python 3.1.3 (r313:86834, may 20 2011, 06:10:42)  [gcc 4.4.5] on linux2 type "help", "copyright", "credits" or "license" more information. >>> len(b'día')   file "<stdin>", line 1 syntaxerror: bytes can contain ascii literal characters. >>> len(b'dia') 3 >>>
