Hi, all. Having a problem with a script that I can't seem to lick. I
*think* I know what the issue is, but I am powerless to fix it.
In short, it will attempt to see if myvar is located in list mylist. If
it does, then something interesting happens. Otherwise, it will sleep
for a bit and try again. (The script will ultimately be for logging
someone out automagically during certain hours of the day). Ok,
script...
-----
import sys, os, time, EasyDialogs
mylist = [ 9, 10, 16, 17, 18, 19, 20, 21]
# If i assign myvar to the below, it works peachy.
#myvar = 9
# If I assign myvar to the system time, it fails. always.
myvar = time.strftime('%H')
# All below this works fine. you can cheerfully ignore it.
try:
mylist.index(myvar)
except ValueError:
EasyDialogs.Message('No problems. Sleeping. blah blah...')
else:
EasyDialogs.Message('something interesting happens here...')
-----
Ok. if I set the myvar to time.strftime('%H') it will always fail, even
when I try to set the clock back, et. al. I run a 'type' against it and
get:
>>> import time
>>> time.strftime('%H')
'18'
>>> type (time.strftime('%H'))
<type 'str'>
So it looks like I am getting a string back instead of an integer. If I
just assign it a number and run type on it again it looks OK...
>>> myvar = 9
>>> type(myvar)
<type 'int'>
I'm sure I have not looked hard enough, but I can't see any way to
change a string to an int. I *imagine* it would be something kinda
like:
time.strftime('%H').something.something()
But I'm stuck and need an extra bit of cleverness to fix this. At the
moment I am *assuming* the string .vs int. thing is the issue, would
love to know if it's really something else I have not run into yet.
Sorry for the length, but would rather soak you with all I have than be
inscrutable. Thanks in advance for any bits that may help out.
P.S. First newbie post! :D
Cheers!
