Int and string types

[temimam]

I’m working on a personal project and I’m getting user from input that should be and int.
problem is like this:
say I get an input from a user using this code:

guess=int(input('what is your guess?:'))

and the user inserts a letter just to be annoying
I’m gonna be getting a syntax error cause the program can’t change the letter to an integer
but if I do this

guess=input('what is your guess?:')

without the int() command all input I get will be treated as a string and not as an int like I want it to
what do I do now?

[temimam]

full code if needed:

import random 
number=random.randint(1,10)

guess=int(input('what is your guess?:'))

if guess not in range(1,10) or guess == 0:
  print('your guess should be a number between 1 and 10')

while guess is not number:
 guess=int(input('guess again:'))

 if guess not in range (1,10) or guess == 0:
   print('your guess should be a number between 1 and 10')

 if guess == number:
  print('great job you guessed correctly!')

There are methods enabling use to check if the value is numeric:

https://www.includehelp.com/python/difference-between-string-isdecimal-isdigit-isnumeric-and-methods.aspx

you could also handle the exception.

I would personally opt for handling the exception. Then you are absolute the conversion was successful (or unsuccessful)

hi @stetim94 thanks for the advice!
can you be a bit more specific about this? I’m not sure I understood what you meant.
thanks a lot!

[stetim94]

Specific about what?

When exceptions occur, we can also handle/catch the exception to keep the programming running and try to prompt the user again

[temimam]

how do I get the program to check if its a number or not?
I can’t get to the link.

[stetim94]

isdecimal(), isdigit(), isnumeric() are all methods which we can use to determine if the string only contains decimal, digit or numeric characters

why can’t you get to the link?

[temimam]

my compute is blocked with parent link.
why is this code not working?

if guess.isnumeric():
  guess=int(guess)

I’m still getting strings instead of numbers

[stetim94]

i don’t see the problem:

[temimam]

inputting this

8

gives me this

if guess.isnumeric():
  guess=int(guess)

this should be happening only in this case:

if guess not in range (1,10) or guess == 0:
   print('your guess should be a number between 1 and 10')

[stetim94]

can i see your full code?

[temimam]

import random
number=random.randint(1,10)
guess=int(input('what is your guess?:'))

if guess not in range(1,10) or guess ==0 and guess.isnumeric():
  print('your guess should be a number between 1 and 10')

while guess is not number:
 guess=input('guess again:')
 
 if guess not in range (1,10) or guess == 0:
   print('your guess should be a number between 1 and 10')

 if guess == number:
  print('great job you guessed correctly!')

[stetim94]

you should really break this down into three steps:

first verify the number is numeric
convert the number to integer
now that you have an integer, you can verify the range

[temimam]

thanks @stetim94 !
problem solved!

[stetim94]

I now told you the answer, but i would advise/recommend to reflect how/why you didn’t get to these steps yourself to learn from it

K.O. commander!
