Python之路Python3【第零篇】Python2 & Python3区别持续更新~

print

def print(self, *args, sep=‘ ‘, end=‘\n‘, file=None): # known special case of print
    """
    print(value, ..., sep=‘ ‘, end=‘\n‘, file=sys.stdout, flush=False)

    Prints the values to a stream, or to sys.stdout by default.
    Optional keyword arguments:
    file:  a file-like object (stream); defaults to the current sys.stdout.
    sep:   string inserted between values, default a space.
    end:   string appended after the last value, default a newline.
    flush: whether to forcibly flush the stream.
    """
    pass

Python2中print是一个语句，只需要向吧输出的放在print关键字后面就可以输出。

Python3中从上面的代码中可以看出他现在是一个函数，就像其他函数一样，print()需要您将要输出的内容作为参数传给他。
