input_var = input ("Press 'E' and 'Enter' to Exit: ")
NameError: name 'e' is not defined
I am using Python 2.5. How I can overcome this error?
回答1:
input reads and evaluates a Python expression. When it tries to evaluate it, it looks for a variable e, which is not defined, and fails.
You almost always want to use raw_input instead. (And in Python3, input has this behaviour.)
Or, better, on Unix, use readline so the user can edit their input.
