KEY DIFFERENCES FROM PYTHON 3
$ # Python 2 syntax
print "hello" # Statement
raw_input("Name: ") # User input
unicode_string = u"text" # Unicode prefix
5 / 2 == 2 # Integer division
print "hello" # Statement
raw_input("Name: ") # User input
unicode_string = u"text" # Unicode prefix
5 / 2 == 2 # Integer division
CAVEATS
