python如何打印字符串

# str.pyclass DisplayClass:
    """
    __repr__ is used everywhere, except by print and str when a __str__ is defined.
    __str__ to support print and str exclusively
    """
    def __repr__(self):
        return "display __repr__ class"
 
    def __str__(self):
        return "display __str__ class"# 使用命令行的形式打印输出  2.x & 3.x 输出效果一致,以2.x作为截图>>> d = DisplayClass()>>> d                   # 调用repr>>> print(d)            # 调用str>>> print(repr(d))      # 调用repr>>> print(str(d))       # 调用str
