当程序尝试进行除法运算,但除数为零时,Python会引发ZeroDivisionError异常。在给定的代码中,除法操作a / b中b的值为0,因此会导致除以零的错误,从而引发ZeroDivisionError异常。故A正确。 B. FloatingPointError:表示浮点数运算错误。它通常与浮点数计算中的溢出、下溢或不精确的结果相关。故B不正确。 C. SyntaxEr...
By default, Python displays floating-point numbers with six digits after the decimal point. However, we can override this behavior by explicitly specifying the precision using '0f'. For example: value = 3.14159 print(format(value, '0f')) This code will output '3.141590' as 6 is the defaul...

This requires the use of a semicolon, which is rarely found in Python programs: Python import pdb; pdb.set_trace() While certainly not Pythonic, it stands out as a reminder to remove it after you’re done with debugging. Since Python 3.7, you can also call the built-in breakpoint(...
