Automatically catch many common errors while codingOne of the most common complaints about the Python language is that variables are Dynamically Typed. That means you declare variables without giving them a specific data type. Types are automatically assigned at based on what data was passed in:https://medium.com/media/b78d1ea3a964819f121e6ac9a35be202/hrefIn this case, the variable president_name is created as str type because we passed in a string. But Python didn't know it would be a string until it actually ran that line of code.By comparison, a language like Java is Statically Typed. To create the same variable in Java, you have to declare the string explicitly with a String type:https://medium.com/media/5137ff461ab2b20bb76a02dafab41eba/hrefBecause Java knows ahead of time that president_name can only hold a String, it will give you a compile error if you try to do something silly like store an integer in it or pass it into a function that expects something other than a String.Why should I care about types?It's usually faster to write new code in a dynamically-typed language like Python because you don't have to write out all the type declarations by hand.
