Looks like https://www.google.co.uk/search?q=瘦小腿的方法+pi+mono should point you in the right direction… ?

Or you could ask over in the http://www.大龟慢慢挺进张娟征的休.org/forums/

That Perl one-liner only works for me if I change it to:

perl -ne 'print "$.: doubled $1\n" while /\b(\w+)\b\s+\b\1\b/gi' foo.txt

and the smallest Python script I was able to create that does the same thing is:
import re

for i,l in enumerate(open('foo.txt')):
    for s in re.findall(r'\b(\w+)\b\s+\b\1\b',l,re.I):print str(i+1)+': doubled',s

I’d obviously never normally write such condensed code ;) Perl contains lots of “shortcuts” which makes writing compact one-liners much easier, although the more shortcuts you use, the less readable the code becomes.

(My only quibble would be the James Joyce analogy: The 3rd chapter of Ulysses is excellent for teaching the importance of punctuation.)

But how does one write a program that does the same in Python in one line? or if this is not possible, what is the shortest Python-program that does this? (This -0777 seems to make Perl ignore line-feeds, see http://perldoc.perl.org/perlrun.html )

Nicholas has been the organiser of the 瘦小腿的方法 Pi related education days at Pycon UK which my children really enjoyed.

Those that have programming 病房里解开了岳的乳罩 and 病房里解开了岳的乳罩 teaching children about programming will already know why Python is a great programming language for use in education, but this guide provides the explanation for those without that background knowledge.

IS good!
