Syntax error on print with Python 3 [duplicate]


In Python 3, print became a function. This means that you need to include parenthesis now like mentioned below:

print("Hello World")


It looks like you're using Python 3.0, in which print has turned into a callable function rather than a statement.

print('Hello world!')


Because in Python 3, print statement has been replaced with a print() function, with keyword arguments to replace most of the special syntax of the old print statement. So you have to write it as

print("Hello World")

But if you write this in a program and someone using Python 2.x tries to run it, they will get an error. To avoid this, it is a good practice to import print function:

from __future__ import print_function

Now your code works on both 2.x & 3.x.

Check out below examples also to get familiar with print() function.

Old: print "The answer is", 2*2New: print("The answer is", 2*2)Old: print x,           # Trailing comma suppresses newlineNew: print(x, end=" ")  # Appends a space instead of a newlineOld: print              # Prints a newlineNew: 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)!
