@date 2020/03/06一行代码优化输出的异常信息
pip install pretty-errors写一个函数测试：
def divided_zero():
for i in range(10, -1, -1):
print(10/i)
divided_zero()在没有import这个pretty-errors前，输出的错误信息有些冗余：
Traceback (most recent call last):

ZeroDivisionError: division by zero我们使用刚安装的pretty_errors，import下:
import pretty_errors
def divided_zero():
for i in range(10, -1, -1):
print(10/i)
divided_zero()此时看看输出的错误信息，非常精简只有2行，去那些冗余信息：
ZeroDivisionError:
division by zero完整的输出信息如下图片所示：
