Why do I receive a syntax error when printing a string in Python 3?
>>> print "hello World"
File "<stdin>", line 1
print "hello World"
SyntaxError: invalid syntax
It looks like you're using Python 3.0, in which print has turned into a callable function rather than a statement.
In Python 3, print became a function. This means that you need to include parenthesis now like mentioned below:
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
But if you write this in a programme and some one using Python 2.x tries to run, they will get an error. To avoid this, it is a good practice to import print function
from __future__ import print_function
Now you 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*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)!
