* Schif Schaf:
Hi,
I've got some text that looks like this:
Lorem [ipsum] dolor sit amet, consectetur
adipisicing elit, sed do eiusmod tempor
incididunt ut [labore] et [dolore] magna aliqua.
and I want to make it look like this:
Lorem {ipsum} dolor sit amet, consectetur
adipisicing elit, sed do eiusmod tempor
incididunt ut {labore} et {dolore} magna aliqua.
(brackets replaced by braces). I can do that with Perl pretty easily:
~~~~
for (<>) {
s/\[(.+?)\]/\{$1\}/g;
print;
}
~~~~
but am not able to figure out how to do it with Python. I start out
trying something like:
~~~~
import re, sys
withbracks = re.compile(r'\[(.+?)\]')
for line in sys.stdin:
mat = withbracks.search(line)
if mat:
# Well, this line has at least one.
# Should be able to use withbracks.sub()
# and mat.group() maybe ... ?
line = withbracks.sub('{' + mat.group(0) + '}', line)
# No, that's not working right.
sys.stdout.write(line)
~~~~
but then am not sure where to go with that.
How would you do it?
I haven't used regexps in Python before, but what I did was (1) look in the
documentation, (2) check that it worked.
<code>
import re
text = (
"Lorem [ipsum] dolor sit amet, consectetur",
"adipisicing elit, sed do eiusmod tempor",
"incididunt ut [labore] et [dolore] magna aliqua."
)
withbracks = re.compile( r'\[(.+?)\]' )
for line in text:
print( re.sub( withbracks, r'{\1}', line) )
</code>
Python's equivalent of the Perl snippet seems to be the same number of lines,
and more clear. :-)
Cheers & hth.,
