Invalid syntax when using “print”? [duplicate]

Answer 1

You need parentheses:

print(2**100)

Answer 2

They changed print in Python 3. In 2 it was a statement, now it is a function and requires parenthesis.

Here's the docs from Python 3.0.

Answer 3

The syntax is changed in new 3.x releases rather than old 2.x releases: for example in python 2.x you can write: print "Hi new world" but in the new 3.x release you need to use the new syntax and write it like this: print("Hi new world")

check the documentation: http://docs.python.org/3.3/library/functions.html?highlight=print#print

Answer 4

That is because in Python 3, they have replaced the print statement with the print function.

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, y))      # Not the same as print(x, y)!
