Regex in python for special characters

Question

I need to find whether a given string is in this format or not.

anystr3ing1 : somesrritn3g

following is my code

prog = re.compile("([a-zA-Z0-9]\D)" + ":" + ([a-zA-Z0-9]\D)")

with open('data.txt','ru') as openfileobject:
  for line in openfileobject:
    if prog.match(line):
      print line

however its not giving any output

You have a syntax error. Is this the case in your actual code? Look at the first line, you are missing a " between + and ([a-zA-Z0-9]\D)") near the end of the line. — idjaw

Change the regex to:

[a-zA-Z0-9]+\s+:\s+[a-zA-Z0-9]+

Your problem is that you only matched one character from the class [a-zA-Z0-9], followed by a non digit character, then ":" followed by [a-zA-Z0-9].
