Hi,
For following:
aaa
model 0
bbb
acb
model 1
ccc
How can I set regexp1 as "model 0" and end "model 1"
In English, we have a saying "When all you have is a hammer, everything looks
like a nail". Don't make the mistake of thinking that regexes are your hammer.
In my opinion, this example is best solved with a filter function, not a
regex. Here is a simple example:
def filter_lines(lines, start, end):
lines = iter(lines)
# Skip lines before matching start.
for line in lines:
if line == start:
yield line
break
# Show lines after matching start, but before matching end.
for line in lines:
if line == end:
break
yield line
text = """aaa
model 0
bbb
acb
model 1
ccc
"""
And the output:
py> for line in filter_lines(text.split('\n'), 'model 0', 'model 1'):
... print line
...
model 0
bbb
acb
