= is an assignment operator, meaning you are assignment x to that value, thus the if is always true. use == when doing a comparison.

that is saying if x is greater than a. Sorry if I don't understand your question correctly. Is > also giving you invalid syntax?

when using input(), the data read in is put into a string variable, even if you only give it an integer. I haven't delved too much into python yet, but I'm sure there's a way to convert the string to an integer or the other way around, but type conversions like that are not guaranteed to work flawlessly.
