This program segment allows an invalid date to go undetected. See below.
from datetime import datetime
import time
def set_time_stamp(d1):
# yyyy/mm/dd hh:mm:ss in, vyyyymmdd_hhmmss.27 out
formatin = '%Y/%m/%d %H:%M:%S'
d1 = d1.lstrip()
try:
date1 = datetime(*(time.strptime(d1, formatin)[0:6]))
except ValueError:
print; print "Invalid date input. Use yyyy/mm/dd hh:mm:ss."
return False
formatout = '%Y%m%d_%H%M%S'
dout = date1.strftime(formatout)
print "dout: ",dout
return 'v'+date1.strftime(formatout)+".27"
keyopt = 0
while keyopt == 0:
print
date_time = raw_input("Enter date and time: ")
if date_time == "end":
break
file_prefix = set_time_stamp(date_time)
print "prefix: ",file_prefix
if file_prefix == False:
continue
print "OK: ", file_prefix
#write_pair(file_prefix, date_time)
print; print "bye..."
