grok how to use subprocess.
I am trying to call sox (fun fact: an early contributer to sox was none other
than Guido van Rossum)
In the old days you would just use os i guess, like:
import os
os.system('sox -V3 -D -

Thanks David. Those are excellent short clear examples. I will look those over.
Super! Thanks for that.

On top of that we have the excelent PyMOTW from Doug on subprocess
I have made an extensive script that runs fine when started from the command
line or IDLE.
When I try to run it with cron it keeps giving errors:
Error in sys.exitfunc:
Traceback (most recent call last):

Hi, just started python at Uni and think i am in for a rough ride with zero
prior experience in programming.
Anyway my problem that i can't fix my self after googling.
The exercise is to generate a list of odd numbers between 1-100 and the same
for even numbers.
So far this is what i haveCODE: SE

Hint: You can designate a start number before the first colon.

Hi List
I apologise in advance for the vagueness of this query, but I am looking
for a decent modern introduction to modelling using Python.
Specifically, I want something that is a good introduction (i.e. doesn't
expect one to already be a maths/ statistics or a programming guru) and
that h
Having a problem finding the first 1000 prime numbers, here is my code:-
print(2)
n =3
counter =1
while counter <=1000:
for x in range(3,int((n**0.5)),2):
if n%x != 0:
print(n)
n+=1
counter+=1
else:
n+=1
The problem is, it prints 2 and then does nothing, yet if i
>>> [x for x in range(3,int((n**0.5)),2)]
[]
your while loop is an infinite loop. Had you read the range documentations ?
>>> range(3,int((n**0.5)),2)
[]
>>> n**0.5
1.7320508075688772
>>> n = 3
>>> n ** 0.5
1.7320508075688772
>>> int ( n ** 0.5)
1
>>> range ( 3, 1, 2)
[]

That certainly isn't efficient! In Python 2.x, this
16 matches
