After quizzing newbies in C on swapping without 3rd variable, I found this
to be really *cool* construct to swap :)
x = 10
y = 20
x,y = y,x

You can source the file in python provided that you make it python
friendly:-
STN_id[1]='AAA' instead of STN_id[1]=AAA
...
---
import re
# Read the file
fd = open('sitelocations')
lines = fd.readlines()
fd.close()
# Make it python friendly: put all values in 'single quotes'
cmd = '\n'.joi
I think you need to use "raw_input" instead of "input". input "eval" the
input expression while "raw_input" just stores it. I find the module help
very handy when I am in doubt.
>>> print raw_input.__doc__
raw_input([prompt]) -> string
Read a string from standard input. The trailing newline is s
If the ease of use is the only answer then the size of the file should not
matter ideally. btw, how large is the file ? is it in MBs or GBs ? For
performance reasons, typically you should not have any problems using either
dictionary, array or list for file size of few KBs.
Like Kent said, if you
w.r.t. prob 2, there is no break/continue in the code that you have given. I
added the "break" statement after you remove the word from lstB and code
does seems to work for me.
if word in lstB:
lstB.remove(word)
print
print "Removed",
So, even though you created a new variable lstB it was actually modifying
lstA.

Hi Dick,
You are deleting from the SAME list that you are traversing. This results in
problems. You should just create a new list for the elements that are
well-formed.
astr = ...
lstA = ...
def wellFormed(word) :
for ch in word :
if ch not in astr :
return False
return True
fi
n.readlines()
for i in xrange(N) :
print solve(lines[i])
I will start working on psyco ... though not sure what is it ?
Thanks again Kent.
Cheers

Hi !!
I was trying to solve SPOJ (www.spoj.pl) problems - ADDREV (add reversed
numbers).
My solution clocked 0.58 seconds in SPOJ's computer as compared to best time
of 0.28. Interestingly my program spends 50% of its total execution time in
reading/parsing the input.
Following is the sample inpu
A bug:
The function random.randint(a,b) include both ends
i.e. b is also included. Thus for file with single
line a=0,b=1 my algo will give an IndexError.
Significance of number 4096 :
file is stored in blocks of size 2K/4K/8K (depending
upon the machine). file seek for an offset goes block
by blo
mMem(filename)
getrandomline2("shaks12.txt")
Caveat : It will still skip 1st line during random
selection if its size exceed 4096 chars !!

An alternative approach (I found the Yorick's code to
be too slow for large # of calls) :
We can use file size to pick a random point in the
file. We can read and ignore text till next new line.
This will avoid outputting partial lines. Return the
next line (which I guess is still random :)).
