The tutor seeks to clarify some ideas about Python’s print<\/span> command.<\/h1>\n

I refreshed Python on one of my computers yesterday; I uninstalled Python 2.7, then installed Python 3.4 instead. To do so, I went to python.org<\/a>. I was using a Windows 7 computer at the time; the site suggested a download for me, so I just followed its lead. Later I tried a test script. The whole process took inside of 10 minutes. Everything works flawlessly, so far as I know.<\/p>\n

Of course, there are differences between Python 2.x and 3.x. A key one that might affect people still running Python 2.x concerns the print<\/span> command.<\/p>\n

In Python 2.x, print<\/span> doesn’t require brackets. Therefore,<\/p>\n

print “Hello!”   #2.x<\/span><\/span><\/p>\n

works perfectly. However, in Python 3.x, brackets are required:<\/p>\n

print(“Hello!”)   #3.x<\/span><\/span><\/p>\n

In 2.x, print<\/span> always attaches a newline. Therefore,<\/p>\n

print “Hello!”<\/span>
\nprint “Ciao!”<\/span><\/p>\n

will give the output
\n
\nHello!
\nCiao!
\n<\/span><\/p>\n

In 3.x, you can stop the newline’s being added with end=” “<\/span>:
\n
\nprint(“Hello!”, end=” “)
\nprint(“Ciao!”)<\/span><\/p>\n

gives the output
\n
\nHello! Ciao!
\n<\/span><\/p>\n

To my knowledge, the end=” “<\/span> trick doesn’t work in Python 2.x.<\/p>\n
