```

from datetime import datetime

strDoB = input("Enter your date of birth:")
strFormat = '%d/%m/%Y' # The date should be numeric in the format dd/mm/yyyy

objDoB = datetime.strptime(strDoB, strFormat)   #get the users date of birth
# Get current date
objDateNow = datetime.now()
#work out the difference in days between the two dates
dayDiff = objDateNow - objDoB
#Calculate days difference - allows for leap years
yrsOld = int(dayDiff.days / 365.25)
print("You are {} years old, ".format(yrsOld)))

```
```
