This means that you need to include parenthesis now. print("Hello World") http://docs.python.org/3.0/whatsnew/3.0.html#print-is-a-function share|improve this answer edited Aug 9 '15 at 23:35 Mateusz Grzejek 5,67321336 answered May 5 '09 at 21:21 Unknown 29.6k15104162 add a comment| up vote 40 down vote It looks like you're using Python 3.0, in which print has turned into a callable function rather than a statm

typical release, and more that are important for all Python users. Nevertheless, python print function after digesting the changes, you'll find that Python really hasn't changed all that much - by and large, we're python 3 print without newline mostly fixing well-known annoyances and warts, and removing a lot of old cruft. This article doesn't attempt to provide a complete specification of all new features, but instead tries to give http://stackoverflow.com/questions/826948/syntax-error-on-print-with-python-3 a convenient overview. For full details, you should refer to the documentation for Python 3.0, and/or the many PEPs referenced in the text. If you want to understand the complete implementation and design rationale for a particular feature, PEPs usually have more details than the regular documentation; but note that PEPs usually are not kept up-to-date once a feature has been fully implemented. https://docs.python.org/3/whatsnew/3.0.html Due to time constraints this document is not as complete as it should have been. As always for a new release, the Misc/NEWS file in the source distribution contains a wealth of detailed information about every small thing that was changed. Common Stumbling Blocks¶ This section lists those few changes that are most likely to trip you up if you're used to Python 2.5. Print Is A Function¶ The print statement has been replaced with a print() function, with keyword arguments to replace most of the special syntax of the old print statement (PEP 3105). Examples: 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, y)) # Not the same as print(x, y)! You can also customize the separator between items, e.g.: print("There are <", 2**32, "> poss
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 https://www.codecademy.com/en/forum_questions/52f295c8631fe9ccd000079b result of copy/pasting the various 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 syntax error be appreciated. Thanks. 3 votes permalink Originally, print was a 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 print syntax error a command in order to be compatible with older versions on Python, and is available 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
