在Python中,我们通常使用内置函数如int()、float()、str()等来实现数据类型转换,而change函数则可以进一步封装这些内置函数,实现更加灵活和便捷的数据处理。 假设我们有一个字符串变量s,我们想将其转换为整数类型。使用change函数可以很方便地实现这一转换,例如: ```python def change(s): return int(s) ``` ...

Python doesn't support hexadecimal output viaold-style formattingnor with format() or f-strings. "%a" means string conversion with ascii(): >>> "%a" % 3.14 '3.14' >>> ascii(3.14) '3.14' It's same as str/repr for floats.
