I have a couple problems with this program.
I am using a tuple that contains all of the months and want to be able to get the user to re-enter the data if they enter in invalid month, day or year ? Here is the code I have so far: months = ("january", "february", "march", "april", "may", "june", "july", "august", "september", "october", "november", "december") while True: bmonth = raw_input("Please enter your Birth Month: ") bmonth = bmonth.lower() for mymonth in months: if mymonth == bmonth: print "you have entered a valid month" else: print "you need to print a valid month" raw_input("\n\nPress the enter key to exit.") Also I cant seem to get a formula to work with integers that will calculate the person's age any help I can get would be appreciated ![]() |

Those lines
Code:
for mymonth in months: if mymonth == bmonth: Code:
if mymonth in bmonth: But as for calculating a person's age, do you need just the number of years ? Or do you also want months, days ?

this isnt the most efficant way,but its something to give ya an idea: Code:
import time
date=time.ctime()
cmonth=date[4:7] #current month
cday=int(date[8:10]) #current day
cyear=int(date[20:24]) #current year
month=raw_input('month?')
day=int(raw_input('day?'))
year=int(raw_input('year?'))
if month == 'January':
month=int('01')
elif month == 'Febuary':
month=int('02')
elif month == 'March':
month=int('03')
#etc etc etc
if cmonth == 'Jan':
cmonth=int('01')
elif cmonth == 'Feb':
cmonth=int('02')
elif cmonth == 'Mar':
cmonth=int('03')
#etc etc etc
age = cyear-year
if month > cmonth:
print age-1
elif month < cmonth:
print age
else:
if day < cday:
print age
elif day > cday:
print age-1
else:
print 'Happy Birthday!'
print age

Not a problem at all, the time module provides everything we need and the math is very easy so here goes
.Code:
#!/usr/bin/env python
import time
while True:
print 'Please enter dates in the following format - DD/MM/YYYY\n'
birth = raw_input('Date of Birth: ')
try:
born = time.strptime(birth, '%d/%m/%Y')[:3]
date = time.localtime()[:3]
print int(float('%d.%d%d' % (date)) - float('%d.%d%d' % (born))), '\n'
except:
print 'An error occured while processing your entry...\n'
I wasn't really sure how acurate you wanted this (to the day) but the program will return an int of the users age in years acurate up the the their birthday i.e. 18. You can change the input format to anything you want, see the time module for more info on that: http://www.python.org/doc/2.3.3/lib/module-time.html Note: this is untested so if it doesn't work let me know, although i see no reason why it shouldn't .Mark. |

Chief brought it to my attention that my script brakes when the day and or month is a two digit int i.e 10, 11, 12.
Luckily this can easily be fixed by padding each number using string formatting .Code:
#!/usr/bin/env python
import time
while True:
print 'Please enter dates in the following format - DD/MM/YYYY\n'
birth = raw_input('Date of Birth: ')
try:
born = time.strptime(birth, '%d/%m/%Y')[:3]
date = time.localtime()[:3]
print int(float('%04d.%02d%02d' % (date)) - float('%04d.%02d%02d' % (born))), '\n'
except:
print 'An error occured while processing your entry...\n'
Thanks again Chief, Mark. |

I attempted to run the code that was supplied but it keeps erroring out.
I gues it may have to do with me runing this on a windows box, I may have to have the user enter in all the variables manually and then change them to an integer after combining them. Any suggestions ? ![]() |

Mmmm no, there shouldn't be a problem with either since Chief and i both have windows boxes and we've both been messing around with it without any problems. Whats the error?
Note: if you're not using Python 2.3 then you'll need to change 'True' to '1'. Mark. |
