Hello Tutors,
I'm trying to get a grip on MULTILINE and I guess I don't have it.
Here's some code:
#!/usr/bin/env python
import re
def sub_it(mo):
return 'xxx'
def test(re_str, data):
return re.sub(re_str, sub_it, data, re.MULTILINE)
if __name__ == '__main__':
data = '''Betty Boop:245-836-2837:6937 Ware Road, Milton, PA
93756:9/21/46:43500
Norma Corder:397-857-2735:74 Pine Street, Dearborn, MI 23874:3/28/45:245700
James Ikeda:834-938-8376:23445 Aster Ave., Allentown, NJ 83745:12/1/38:45000
'''
re_str = r'''(d+)$'''
print test(re_str, data)
re_str = r'''(d+)'''
print test(re_str, data)
'''
./re_test2.py
Betty Boop:245-836-2837:6937 Ware Road, Milton, PA 93756:9/21/46:43500
Norma Corder:397-857-2735:74 Pine Street, Dearborn, MI 23874:3/28/45:245700
James Ikeda:834-938-8376:23445 Aster Ave., Allentown, NJ 83745:12/1/38:xxx
Betty Boop:xxx-xxx-xxx:xxx Ware Road, Milton, PA xxx:xxx/xxx/xxx:43500
Norma Corder:397-857-2735:74 Pine Street, Dearborn, MI 23874:3/28/45:245700

If I don't anchor it with '$', it gets all the digit-groups in the first line
except the last one. Why not the last one? Whay not the other lines?
If I do anchor it, it only gets the last group on the last line. What's up
with that?
What I really want, is to mess with each of the last digit-groups on each line.
But I can't find them.
The exercise is from Ellie Quigley's "Perl by Example"
Thank you for any help.
