The syntax is now more or less the same as before, but it requires parens: From the "what's new in python 3" docs: Old: print "The answer is", 2*2 New: print("The answer is", 2*2) Old: print x, # Trailing comma suppresses newline New: print(x, end=" ") # Appends a space instead of a newline Old: print # Prints a newline New: print() # You must call the function! Old: print >>sys.stderr, "fatal error" New: print("fatal error", file=sys.stderr) Old: print (x, y) # prints repr((x, y)) New: print((x
delarsen5 over 2 years ago Print Syntax Good Afternoon, I've started to program the challenges alongside the Codecademy lessons in Python (v3.3.3), and as a result of copy/pasting the various https://www.codecademy.com/en/forum_questions/52f295c8631fe9ccd000079b challenges, I noticed a syntax issue with print. In Codecademy Editor: print "Hello World" Returns successfully without error. In Python: print "Hello World" Returns a syntax error. It wants parentheses around the item to be printed. print("Hello World") Returns successfully. I may have missed the reasoning for this in an earlier lesson, but any input would be appreciated. Thanks. 3 votes permalink Originally, print was a syntax error Python command, and not a function. The output did not need to be enclosed in parentheses. In Python 3.x, print is a built-in function, and no longer a command. The output, consisting of 0 or more arguments, needs to be enclosed in parentheses. In Python 2.7, which Codecademy uses, print exists as a command in order to be compatible with older versions on Python, and is available python 3 print as a built-in function, for compatibility with newer versions. So, you can get print to work with or without parentheses.

If I want to master Python programming language, should i need to learn Python 3? Does it have more differences with Python 2? 0 votes permalink It's actually a little more complicated than what I described above. Technically print is a "special syntax statement/grammar construct" in Python 2.x, so in some circumstances you may see differences in behavior between it and the Python 3.x print function. To disable it as a command, and access it as a true function so that it behaves the same as in Python 3.x, use: from __future__ import print_function Without the import, you'll notice that the following statement outputs a tuple: print(1, 2, 3) Here's some interaction in IDLE for
