check if table/record exists in mysql

I want to create scripts to create a database/schema and seed data in mysql as such, pseudo code below

if the table doesn't exits is true
    then create table

Note - I don't want to drop table before  creating it , just want to check if it exits or not ,

another way i was thinking was, which is less code , more like a try and catch block in other languages , such that if there is already a table by that name, it throws an exception and
i don't do anything .

try {

         create table MyTable
      }

Catch {
              //do nothing
   }

Also, if i version these scripts , such that

script 1
script 2
script 3,

is there a way, I can run this and make changes to my database from whatever folder i am in  , instead of having to copy the content of the scripts to the query window in mysql workbench
