python - How to check last digit of number

Question

Is there a way to get the last digit of a number. I am trying to find variables that end with "1" like 1,11,21,31,41,etc..

If I use a text variable I can simply put

print number[:-1] 

but it works for variables with text(like "hello) but not with numbers. With numbers I get this error:

TypeError: 'int' object is not subscriptable

I am trying to see if there's a better way to deal with numbers this way. I know a solution is to convert to a string and then do the above command but I'm trying to see if there's another way I have missed.

Thanks so much in advance...

Answer 1

Remainder when dividing by 10, as in

numericVariable % 10

This only works for positive numbers. -12%10 yields 8
