"Completely incompatible"? A "lie"?
Hard word, but it is true. Many things can and will fall on your feet
when moving.
There are very many subtle differences.
import math
import random
my_list = [3, 5, 7, 9]
n = random.choice(my_list)
if n%3:
func = math.sin
else:
func = math.cos
y = func(math.pi/n)*10
L = ['spam']*(int(y))
for item in L:
print(item)
is valid syntax in every version of Python from 1.5 to 3.2, and it does
the same thing in all of them.
C and C++ guys complain if these languages are intermixed. Even there it
is possible to write a program which is valid in both of them.
Nevertheless, they are two different languages.
So are Py2 and Py3, IMHO.
