Hi Jeff,

hello I am having trouble with using the re module. I have a statement:
line = FileHandle.readline(-1) test = findall('\d', line) where "line" is a line of text from a file I would like to read and extract numbers from. the line is simply three numbers, example 3.444456 4 84.3546354. I want to put these number in "test" but the findall expression seems to only take whole numbers, so for example test would be for the above numbers [3, 4, 4, 4, 4, 5, 6, 4, 8, ....]. How is this done so that test = [3.444456 4 84.3546354]?
re.findall(r'\d+.?\d*', '3.444456 4 84.3546354') ['3.444456', '4 ', '84.3546354']
I fell that, you are looking for this:
re.findall('\S+', '3.444456 4 84.3546354') ['3.444456', '4', '84.3546354']
Yours sincerely, János Juhász -------------- next part -------------- An HTML attachment was scrubbed... URL: http://mail.python.org/pipermail/tutor/attachments/20040701/01d0f804/attachment.html
