[Tutor] Re:[Tutor]Question on python

[sachin mehra]

Hi,
Well I want to use the following commands:
tr -cs '[:aplha:]' '[\n*]' < *.txt | uniq -c | sort -rm | more

Which would give me a count of unique words in a .txt file..
How can i use this..I have already tried the os.system option!!
I may need to use this command(or similar type) a few more times..How can I 
do it in python?
Thanx,
manish
