sleep() function, perhaps.

[Ryan Spencer]

Hello Everyone,

I want to have a row of periods, separated by small, say, .5 second
intervals between each other. Thus, for example, making it have the
appearance of a progress "bar".

[code]
import time

sleep(.5)
print "."
sleep(.5)
print "."
[end code]

But, it would (with those .5 second intervals)
print out much like the following.

..
(pause)
..
(pause)

I would rather those periods be on a single line, not printing on a new
line each time.

Any suggestions?

Thank you in advance,
~Ryan

Hey!

Wow! Thanks for all the advice guys. To admit, I'm rather new to python,
but I am understanding thus far and working through all the great advice
you've all given. The spinner is actually very cool, I must say. Also, I
thank you Skip for your progress module, I'll play around with that in a
bit for actually working in coherence with the programs actual progress.

But flushing stdout's buffer does the trick, Which I'm really jazzed to
see. I'm still am heading back through all the other stuff that everyone
else has mentioned though, just to improve my knowledge of course.

I must say though, I previously posted this question on an on line message
board and received no feedback in a matter of weeks, and two days on this
newsgroup and BAM! Haha

Well, Thanks again guys, I'm sure I'll be back with other questions later
;)

Hello Once Again,

Well, Here's the beta, I'll say, for my "bogus" program. Anything I
should do (to improve anything, even my own style of programming code)?

[code]

#Python Excercise number one.
#Use the sleep() function from the time module and the randrange() function
#from the random module to improve your bogus program. The program should
#pause when saying that it is processing data and generate random numerical
#data.

import time, sys, whrandom

#Random numerical data (rnd = Random Numerical Data)
rnd = whrandom.randra nge(5, 150)

print "\nRunning system administration clean-up, please wait...\n"

#Progress bar
for i in range(10):
sys.stdout.writ e('.')
sys.stdout.flus h()
time.sleep(.5)

print ".\n"

print "System administration clean-up complete,", rnd,"MB of space freed from temporary information files.\n"
print "Executing system tune-up procedure, please wait...\n"
time.sleep(5)

#passcode = raw_input("Plea se enter your root password: ")

#rootpass = open("/home/ryan/main/programming/testfile", "w")
#rootpass.write lines(passcode)
#rootpass.close ()

print "Thank you. System tune-up will now continue..."
time.sleep(5)
print "\nSystem tune-up complete. Your system is now running better."
print "Thank you for your patience.\n"

[end code]

I commented out the password part, I was playing around with writing to
files and decided to add that in for the heck of it.

How does it look?

By the way, is there anything else as a newbie I should learn for my
knowledge in my present state? I'm just truly trying to find help. Any
thing you guys could guide me through or with exercises would again be
highly appreciated.

The only background I've had is programming in some C, but small stuff.

Thanks all, Your a tremendous help!

You've got the answer for dots, here's a spinner in case it's useful:

import sys, time

spinner="|/-\\"
pos=0

while 1:
sys.stdout.writ e("\r"+spinne r[pos])
sys.stdout.flus h()
time.sleep(.5)
pos+=1
pos%=4

And a quicky OO version for kicks (untested):

I thought you mean't an " .o0O" version initially
(like cdparanoia)

:-)

Pádraig.
