What is the difference between raw_input() and input() in Python 3?
raw_input() takes exactly what the user typed and passes it back as a string.
input() first takes the raw_input() and then performs an eval() on it as well.
The main difference is that input() expects a syntactically correct python statement where raw_input() does not.
raw_input() was renamed to input() so now input() returns the exact string.input() was removed. If you want to use the old input(), meaning you need to evaluate a user input as a python statement, you have to do it manually by using eval(input()).
