Example program:
import random
random.seed(42)
for i in range(10):
print random.random()
At the start of the program, the random number generator is seeded with
42. This could be any number, but t

It is very hard to know what caused that, but could
you post the piece of code you were trying to execute??
Or did you get
the error when you opened the Pythonwin without any code??

Hi Lin
Hello tutors,
This programm works:
**
import webbrowser
a = open('test.htm','wb')
a.write("Test")
webbrowser.open(a.name)
a.close()
***
but I would like to avoid the risk of overwriting an already existing
"test.htm" file, so I try to use the module tempfile:
***
import tem

Hello, folks. These seems as good as another question to take a first plunge
into your forum.
I would like to---so far without luck--to print out my Python scripts with
syntax highlighting (using Mandrake Linux as my OS/host.) Using enscript has
not gotten me anywhere; nor has a package I fou

Ah, I'd forgotten that in shuffle( x[, random],
"random" would be the default. But please bear with me. Using
your function a, I wrote testShuffle.py:
# testShuffle.py
from random import *
def a():
return 0.5
lst = ['1', '2', '3', '4']
shuffle(lst,a)
print lst
>>>
['1', '4', '2', '3']

Any particular feason to open the file in binary mode?
That can sometimes cause odd things to happen.

The close should come before the browser reads

Dear group,
for mapping a string of protein/nucleotides, BLAST is
one tool that is highly sought. However, its
performance is limited due to some factors and one
such factor is length of the query string. IF the
length of the query string is less than 30 characters,
its output is questionable.
