Python unexpected EOF while parsing

Question

Here's my python code. Could someone show me what's wrong with it.

while 1:
date=input("Example: March 21 | What is the date? ")
if date=="June 21":
    sd="23.5° North Latitude"
if date=="March 21" | date=="September 21":
    sd="0° Latitude"
if date=="December 21":
    sd="23.5° South Latitude"
if sd:
    print sd

And Here's what happens:

>>> 
Example: March 21 | What is the date? 
Traceback (most recent call last):
  File "C:\Users\Daniel\Desktop\Solar Declination Calculater.py", line 2, in <module>
    date=input("Example: March 21 | What is the date? ")
  File "<string>", line 0

   ^
SyntaxError: unexpected EOF while parsing
>>> 

Answer 1

Use raw_input instead of input :)

If you use input, then the data you type is is interpreted as a Python Expression which means that you end up with gawd knows what type of object in your target variable, and a heck of a wide range of exceptions that can be generated. So you should NOT use input unless you're putting something in for temporary testing, to be used only by someone who knows a bit about Python expressions.

raw_input always returns a string because, heck, that's what you always type in ... but then you can easily convert it to the specific type you want, and catch the specific exceptions that may occur. Hopefully with that explanation, it's a no-brainer to know which you should use.

Reference

Note: this is only for Python 2. For Python 3, raw_input() has become plain input() and the Python 2 input() has been removed.
