Dear all,
this is really driving me nuts and any help would be extremely
appreciated.
I have a string that contains some numeric data. I want to isolate
these data using re.match, as follows.
bogus = "IFC(35m)"
data = re.match(r'(\d+)',bogus)
print data.group(1)
I would expect to have "35" printed out to screen, but instead I get
an error that the regular expression did not match:
Traceback (most recent call last):
File "C:\Documents and Settings\Mattia\Desktop\Neeltje\read.py",
line 20, in <module>
print data.group(1)
AttributeError: 'NoneType' object has no attribute 'group'
Note that the same holds if I look for "35" straight, instead of "\d
+". If instead I look for "IFC" it works fine. That is, apparently
re.match will match only up to the first non-alphanumeric character
and ignore anything after a "(", "_", "[" and god knows what else.
I am using Python 2.6 (r26:66721, latest stable version). Am I missing
something very big and very important?
