Cannot seem to use import time and import datetime in same script in Python

Question

I'm using Python 2.7 on Windows and I am writing a script that uses both time and datetime modules. I've done this before, but python seems to be touchy about having both modules loaded and the methods I've used before don't seem to be working. Here are the different syntax I've used and the errors I am currently getting.

First I tried:

from datetime import *
from time import *
...
checktime = datetime.today() - timedelta(days=int(2))
checktime = checktime.timetuple()
...
filetimesecs = os.path.getmtime(webgatelogdir + '/' + fn) 
file = webgatelogdir + '/' + fn
filetime = localtime(filetimesecs)
...
else: time.sleep(60)

ERROR:

else: time.sleep(60) AttributeError: 'builtin_function_or_method' object has no attribute 'sleep'

Then I tried:

from datetime import *
from time import *
...
checktime = datetime.today() - timedelta(days=int(2))
checktime = checktime.timetuple()
...
filetimesecs = os.path.getmtime(webgatelogdir + '/' + fn) 
file = webgatelogdir + '/' + fn
filetime = localtime(filetimesecs)
...
#else: time.sleep(60)  # comment out time.sleep statement

and I got no errors, but no sleep delay either.

Next I tried:

from datetime import *
import time
...
checktime = datetime.today() - timedelta(days=int(2))
checktime = checktime.timetuple()
...
filetimesecs = os.path.getmtime(webgatelogdir + '/' + fn) 
file = webgatelogdir + '/' + fn
filetime = localtime(filetimesecs)
...
#else: time.sleep(60)  # comment out time.sleep statement

ERROR:

filetime = localtime(filetimesecs) NameError: name 'localtime' is not defined

Another modification and I tried this:

import time
import datetime
...
checktime = datetime.today() - timedelta(days=int(2))
checktime = checktime.timetuple()
...
filetimesecs = os.path.getmtime(webgatelogdir + '/' + fn) 
file = webgatelogdir + '/' + fn
filetime = localtime(filetimesecs)
...
#else: time.sleep(60)  # comment out time.sleep statement

ERROR

checktime = datetime.today() - timedelta(days=int(2)) AttributeError: 'module' object has no attribute 'today'

Finally, I tried this:

import time
from datetime import *
...
checktime = datetime.today() - timedelta(days=int(2))
checktime = checktime.timetuple()
...
filetimesecs = os.path.getmtime(webgatelogdir + '/' + fn) 
file = webgatelogdir + '/' + fn
filetime = localtime(filetimesecs)
...
#else: time.sleep(60)  # comment out time.sleep statement

ERROR:

checktime = datetime.today() - timedelta(days=int(2)) AttributeError: 'module' object has no attribute 'today'

So I'm not sure how to get the two modules to play nicely. Or I need another method to put a delay in the script.

Suggestions? Or pointers to mistakes that I made?

Thanks.

Answer 1

You can use as while importing time.

import time as t
from datetime import datetime
...
t.sleep(2)

Answer 2

Don't use from ... import * – this is a convenience syntax for interactive use, and leads to confusion in scripts.

Here' a version that should work:

import time
import datetime
...
checktime = datetime.datetime.today() - datetime.timedelta(days=int(2))
checktime = checktime.timetuple()
...
filetimesecs = os.path.getmtime(webgatelogdir + '/' + fn) 
file = webgatelogdir + '/' + fn
filetime = time.localtime(filetimesecs)
...
#else: time.sleep(60)  # comment out time.sleep statement

When importing the modules using import <modulename>, you of course need to use fully qualified names for all names in these modules
