首先将整数转换为二进制字符串,然后遍历每一位并转换为bool值,最后返回bool数组。 状态图 下面是一个状态图,展示了整数转换为bool数组的过程: 1. 将整数转换为二进制字符串2. 遍历每一位3. 将值转换为bool4. 继续遍历下一位5. 结束遍历StartConvertIterateConvert_BoolEnd 总结 通过本文的介绍,我们学习了如何使...
布尔型是最简单的标量类型之一,用于表示真(True)或假(False)两种状态。在函数或变量声明中,只需使用bool作为注解即可: def is_even(number: int) -> bool: return number % 2 == 0 result: bool = is_even(42)2.1.2 数值型(int,float,complex等) 数值型包括整数(int)、浮点数(float)以及复数(complex)...

In this Python tutorial, you learned how toconvert bool to int in Pythonusing the Python built-in function int(). You also learned how theint()function works and what kind of value it can convert into integers. You may like to read: ...
