The most simple way to reverse a number in Python is to convert it to a string, reverse the string, and convert it back to an integer: def reverse_number_string_method(number): """ Reverse a number using string conversion. Args: number: The number to reverse Returns: The reversed numbe...
复数(complex): 复数由实数部分和虚数部分构成,可以用a + bj,或者complex(a,b)表示, 复数的实部a和虚部b都是浮点型。 我们也可以使用十六进制和八进制代表整数: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>number=0xA0F# 十六进制>>>number2575>>>number=0o37# 八进制>>>number31 3.1Python...
