Just started thinking about learning python.
Is there any place where I can get some free examples, especially for
following kind of problem ( it must be trivial for those using python)
I have files A, and B each containing say 100,000 lines (each line=one
string without any space)
I want to do
" A - (A intersection B) "
Essentially, want to do efficient grep, i..e from A remove those lines which
are also present in file B.
You could implement elegantly using the new sets feature
For reference here is the unix way to do it:
sort a b b | uniq -u
