当字符串无法转换为数字时,int()和float()函数会抛出ValueError异常。可以使用try...except块来处理这种情况。 python string_invalid = "abc" try: int_value = int(string_invalid) except ValueError: print("无法将字符串转换为整数") try: float_value = float(string_invalid) except ValueError: print("...

前段时间南京的一起电动车自燃事件造成了众多人员伤亡,引起了大家对电动车起电事件的关注,我觉得在电动车停放区安装一个火焰检测器应该是一个不错的选择,所以我就想到了使用MicroPython基于RP2040开发板实现火焰传感器实时监测。 实验接线图 火焰传感器接线图
