print "testing"
will not work anymore. This will now give you an error :
>>> print "testing"
File "", line 1
print "testing"
^
SyntaxError: invalid syntax
The help function has also been made a function. This means that ....
help
>>> help print()
File "", line 1
help print()
Now you will have to put up the parentheses like so ... help(print)
The map function will also not work like it used to. I am still trying to find out how it works.
>>> def print_me(line):
... print (line)
...
>>> print_me("stuff")
stuff
>>> a = ["print","me","now"]
>>> map(print_me,a)
map object at 0x01765CD0
These means too most of my code would be borked .. sigh! Stuff that I have been using for my client's code like Django and Zope will need to be updated too. This is all I have explored for now. Will write more as I encounter more.
Update: I updated the title a bit after the first comment. Tsk tsk some people can so be so uptight these days.
