+--- Thread: problem using custom exception handling in python (/thread-19531.html)
problem using custom exception handling in python - srm - Jul-03-2019
I am using custom exception in my program along with built in exceptions given by python.
My code is:
class Error(Exception):
pass
class ValueTooSmallError(Error):
pass
class ValueTooLargeError(Error):
pass
# user guesses a number until he/she gets it right
# you need to guess this number
number = 10
while True:
try:
i_num = int(input("Enter a number between 1-10: "))
if i_num < number:
raise ValueTooSmallError
elif i_num > number:
raise ValueTooLargeError
break
except ValueTooSmallError:
print("This value is too small, try again!")
print()
except ValueTooLargeError:
print("This value is too large, try again!")
print()
print("Congratulations! You guessed it correctly.")here I want that if user by mistakes enters a string instead of number, it should give ValueError that is the built-in exception in python...how do i use it with custom defined error...I did try but not getting it...Thanx in advance

Whats wrong with ValueError? Why do you need to define custom errors?

Add a
except ValueError: to go along with the other exceptions.Note:
if i_num < number: is checking the entered number is less 10, it should be checking for less than 1 based on the input requirements.

Why do you even need exceptions? Why not just put the code from the except blocks back into the conditional blocks that raise the errors in the first place?
