[Chennaipy] How to know and prevent type cast errors?

[Shrinivasan T]

Hello all,

I have few programs that fail due to string concating error.

result = variableA + variableB

When variableB is int, it gives type error.

Usually I forget to add type casting for the variables.

Why to avoid this frequent error?

I use emacs editor in Ubuntu Linux.

Adding typecast is the only way to avoid this. But how do you all remember
this?

Is there any easy reminder or error pointer in any other IDE or Tools?

Thanks.
