Behaviour of print

The behaviour of print differs in Python 2 and in Python 3.

In version 7.2, SageMath is using the Python 2 syntax for print. It may soon switch to the Python 3 syntax, where print is a function.

To convert from Python 2 to Python 3, you basically need to add parentheses, and write print("x") instead of print "x".

Here is a conversion table to help you adapt your code:

Python 2

Python 3

print a, b, c

print(a, b, c)

print "%03d" % 7

print("{:03d}".format(7))

print x,

print(x, end=" ")

print >>sys.stderr, x

print(x, file=sys.stderr)
