Similarly, when the “Python interpreter” (the engine) does not know what to do with the “data” (water) that we gave it, the program will get stuck. The Exception object is just an error report generated by the interpreter giving us clues on what went wrong? and where in the progra...
Sometimes you're deep down in the code, and you need to debug an error quickly, send a traceback somewhere or log it into a file. Here's how you can print the traceback of an error in Python: import traceback try: raise Boom('This is where our code blows') except Exception: # ...

掌握如何打印Python异常信息: 在except块中,我们可以使用print函数来打印异常信息。 例如: python try: # 尝试执行可能引发异常的代码 result = 10 / 0 except Exception as e: # 捕获异常,并打印异常信息 print(f"An error occurred: {e}") 此外,还可以使用traceback模块来打印完整的异常堆栈跟踪,这有助...
