Well, you need a web server, a webpage, a database (could just be a
file), a cgi script, and the datetime module. Optionally, you can use a
web framework like CherryPy or Django, which covers a lot of these by
itself.
I only know Python 2, but here are some examples:
A basic web server:
webdir = '.'
port = 80
import os, sys
from BaseHTTPServer import HTTPServer
from CGIHTTPServer import CGIHTTPRequestHandler
if len(sys.argv) > 1: webdir = sys.argv[1]
if len(sys.argv) > 2: port = int(sys.argv[2])
print 'webdir "%s", port %s' % (webdir, port)
#Windows only hack
if sys.platform[:3] == 'win':
CGIHTTPRequestHandler.have_popen2 = False
CGIHTTPRequestHandler.have_popen3 = False
sys.path.append('cgi-bin')
os.chdir(webdir)
srvraddr = ("", port)
srvrobj = HTTPServer(srvraddr, CGIHTTPRequestHandler)
srvrobj.serve_forever()
Start the script in the same directory as the cgi script and HTML.
Assuming you have a file that holds '1' time per date, you could
write a program to pickle and unpickle dictionaries that
are derived from form data:
import pickle
import cgi
file = open('dates.pkl', 'rb')
mydates = pickle.load(file)
file.close()
html = """
<html>
<body>
<h1>Schedule</h1>
<form method=POST action="yourscript.py">
<table border=1>
<tr>
<td><input type=text name=april01 value=%(april01)s></td>
<td><input type=text name=april02 value=%(april02)s></td>
</tr>
<tr>
<td><input type=text name=april03 value=%(april03)s></td>
<td><input type=text name=april04 value=%(april04)s></td>
</tr>
</table>
<input type=hidden name=submitted value=done>
<p><input type=submit>
</form>
</body>
</html>
"""
dates = ['april01', 'april02', 'april03', 'april04']
if form.has_key('submitted'):
newdates = {}
for d in dates:
if form.has_key(d):
newdates[d] = form[d].value
else:
newdates[d] = ''
mydates = newdates
output = open('dates.pkl', 'wb')
pickle.dump(mydates, output)
output.close()
else:
for d in dates:
if not mydates.has_key(d):
mydates[d] = ''
print html % mydates
Then you could write an additional program that runs
in the background or something:
import pickle
from datetime import date, datetime
mycode = 'print "Hello World!"'
file = open('dates.pkl', 'rb')
mydates = pickle.load(file)
file.close()
while True:
today = date.today()
if today.month == 4 and today.day == 01:
hour = datetime.time(datetime.now()).hour
min = datetime.time(datetime.now()).minute
if hour == int(mydates['april04'][0]) and min ==
int(mydates['april04'][-2:]):
exec mycode
_exec_ executes a Python string like a program. To execute an actual
python script use subprocess instead:
import subprocess
subprocess.call(["python", "myscript.py"])
Hope this helps.
