Thanks Cameron, this worked. > > Once you're happy you should consider what happens when there is more than > one > "C#[blah]" in a line (if that happens; you know the data better than we). Now I have this input data: #D{#C[Health] #P[Information] - means any information, including #ST[genetic information], whether #C[oral | (recorded in (any form | medium))], that (1)#C[Is created or received by] a #A[health care provider | health plan | public health authority | employer | life insurer | school | university | or health care clearinghouse]; (2)#C[Relates to] #C[the past, present, or future physical | mental health | condition of an individual] | #C[the provision of health care to an individual] | #C[the past, present, or future payment for the provision of health care to an individual].} The result of my code is this: #C[Health] [<_sre.SRE_Match object at 0x10212ee40>] [<_sre.SRE_Match object at 0x10212ee40>] [<_sre.SRE_Match object at 0x10212ee40>] [<_sre.SRE_Match object at 0x10212ee40>] [<_sre.SRE_Match object at 0x10212ee40>] [<_sre.SRE_Match object at 0x10212ee40>] [<_sre.SRE_Match object at 0x10212ee40>] [<_sre.SRE_Match object at 0x10212ee40>] The code itself: import re import tkinter.filedialog import readfile j = 0 text = [] content = readfile.pattread() constraint = re.compile(r'(#C\[\w*\])') while j < len(content): result = constraint.search(content[j]) if result is not None: text.append(result) print(result.group(0)) print(text) j = j+1 I know that "[<_sre.SRE_Match object at 0x10212ee40>]" is the result of print(text). Does this mean that we ONLY found one match object? What about if I want the code finds also this one? #C[Is created or received by]? or this one? #C[the past, present, or future physical | mental health | condition of an individual] Is it because of the space and other characters that it doesn't match them? -- https://mail.python.org/mailman/listinfo/python-list
