 ## Python Error Types
 
-When we write code it common that we make a typo or other common errors. Based on the type of error we make python raise a kind of error which suggests us to fix it by reading the feedback. Understanding different types of errors in a certain programming language can help us to debug our code quick and in return it makes us a better programmer.
+When we write code it's common that we make a typo or some other common error. If our code fails to run, the python interpreter will display a message, containing feedback with information on where the problem occurs and the type of an error. It will also sometimes gives us suggestions on a possible fix. Understanding different types of errors in programming languages will help us to debug our code quickly and also it makes us better at what we do.
