inp = raw_input() # Get the input while inp != "": # Loop until it is a blank line inp = raw_input() # Get the input again Note that if you are on Python 3.x, you will need to replace raw_input with input .

The inner while loop loops until the input is either 'y' or 'n'. If the input is 'y', the outer while loop starts again (continue keyword skips the remaining code and goes straight to the next iteration). If the input is 'n', the outer while loop breaks and the program ends. Note: I'm using input() in Python 3. In Python 2, use raw_input().

Feb 28, 2017 · While eval operates in a very general context and so much scope for introducing security issues ast.literal_eval is intended to evaluate string literals only and so has a far narrower and hence safer scope.

This prompts the user for text input and returns it as a string. In your case, this will prompt for a file path to be input. If you add an argument to this function, it prints something without a newline before input is requested, for example:
