print SyntaxError: invalid syntax 오류 문제

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:
view source print ? 01 Old: print "The answer is" , 2 * 2 02 New: print ( "The answer is" , 2 * 2 ) 03
04 Old: print x,           # Trailing comma suppresses newline 05 New: print (x, end = " " ) # Appends a space instead of a newline 06
07 Old: print               # Prints a newline 08 New: print ()            # You must call the function! 09
10 Old: print >>sys.stderr, "fatal error" 11 New: print ( "fatal error" , file = sys.stderr) 12
13 Old: print (x, y)       # prints repr((x, y)) 14 New: print ((x, y))      # Not the same as print(x, y)!
You can also customize the separator between items, e.g.:
view source print ? 1 print ( "There are <" , 2 * * 32 , "> possibilities!" , sep = "")
which produces: There are <4294967296> possibilities! Note: * The print() function doesn’t support the “softspace” feature of the old print statement. For example, in Python 2.x, print "A", "B"would write "AB"; but in Python 3.0, print("A", "B") writes "A B". * Initially, you’ll be finding yourself typing the old print x a lot in interactive mode. Time to retrain your fingers to type print(x) instead! * When using the 2to3 source-to-source conversion tool, all print statements are automatically converted to print() function calls, so this is mostly a non-issue for larger projects.

오류 원인:python v3.0 이후 버전에서 v2.x 버전의 print를 print () 로 변경합니다.그래서 여기서 print를 호출합니다("Hello World!").성공할 수 있다.
