How do I improve this python code for improved negative testing? -


i newbie python programming decipher seeing code anyways. know how improve code improve negative testing?

ageinmonths = input("enter age in months: ")  age = int(ageinmonths,10) if type(age) == float:     print("invalid age format entered")  if type(age) == str:     print("invalid age format entered")   years = int(age/12) months = age%12  print("your exact age in years , months is",years,"years",months,"months")

the problem above line of code works fine when enter proper value ex: 56 , 48 etc. in months.

but if happen enter invalid value, error message shown below:

enter age in months: welcome traceback (most recent call last):   file "c:\users\srinivas\documents\python\guess_age.py", line 2, in <module>     age = int(ageinmonths,10) valueerror: invalid literal int() base 10: 'welcome' >>>

i know how improve code add proper error message negative testing invalid search criteria such strings, special characters, floats etc.

i using python 3.6 (32 bit version).

as reut sharabani mentioned, use try ... except block. like:

try:     int("whatever") except valueerror:     print("upss there problem")

note i'm catching valueerror exception, , not exceptions.
