So in my case I want to ensure that numbers are saved in a basic
format.
1) Currency so input limited to 000.00 eg 1.00, 2.50, 13.80 etc
Some GUIs provide this functionality or provide callbacks for validation
functions that can determine the validity of the input. ? don't know of
any modules that provide formatted input in a terminal. ?ost terminal
input functions just read from stdin (in this case a buffered line)
and output that as a string. ?t is easy enough to validate whether
terminal input is in the proper.
Your example time code might look like:
... import re
... import sys
...
... # get the input
... print(Please enter time in the format 'MM:SS:HH': , end=)
... timeInput = input()
...
... # validate the input is in the correct format (usually this would be in
... # loop that continues until the user enters acceptable data)
... if re.match(r'''^[0-9]{2}:[0-9]{2}:[0-9]{2}$''', timeInput) == None:
... ??print(I'm sorry, your input is improperly formated.)
... ??sys.exit(1)
...
... # break the input into its componets
... componets = timeInput.split(:)
... minutes = int(componets[0])
... seconds = int(componets[1])
... microseconds = int(componets[2])
...
... # output the time
... print(Your time is: + %02d % minutes + : + %02d % seconds + : +
... ??%02d % microseconds)
Currency works the same way using validating it against:
r'''[0-9]+\.[0-9]{2}'''
For sports times that is time duration not a system or date times
should I assume that I would need to calculate a user input to a
decimal number and then recalculate it to present it to user?
I am not sure what you are trying to do or asking. ?ython provides time,
date, datetime, and timedelta objects that can be used for date/time
calculations, locale based formatting, etc. ?hat you use, if any, will
depend on what you are actually tring to accomplish. ?our example doesn't
really show you doing much with the time so it is difficult giving you any
concrete recommendations.
yes you are right I should have clarified. The time is a duration over
distance, so its a speed measure. Ultimately I will need to store the
times so I may need to use something likw sqlAlchemy but I am nowehere
near the advanced but I know that most Db's mysql, postgre etc don't
support time as a duration as such and i will probably need to store
it as a decimal and convert it back for the user.

You can let a user to separately input the days, hours, minutes, etc.
And use the type timedelta to store the time duration:
datetime.timedelta([days[, seconds[, microseconds[, milliseconds[, minutes[,
hours[, weeks]]])
Beyond 2.7, you can use timedelta.total_seconds() to convert the time
duration to a number for database using. And later restore the number
back to timedelta by timedelta(seconds=?).

User input masks - Access Style
Is there anyay to use input masks in python? Similar to the function found in access where a users input is limited to a type, length and format. So in my case I want to ensure that numbers are saved in a basic format. 1) Currency so input limited to 000.00 eg 1.00, 2.50, 13.80 etc For sports times that is time duration not a system or date times should I assume that I would need to calculate a user input to a decimal number and then recalculate it to present it to user? So an example, sorry. import time #not sure if this is any use minute = input(How many minutes: ) seconds = input(How many seconds: ) Hundredths = input(how many Hundredths: ) # convert user input MyTime = (minute/60)+(seconds)+(Hundredths/1800) #Display to user assuming i had written a name and user # had retrieved it print([User], your time was), (MyTime/60:MyTime(MyTime-((MyTime/ 60)*60).(MyTime-(MyTime0))) ) -- http://mail.python.org/mailman/listinfo/python-list

Sorry, you need to check to make sure that there are no trailing characters
