浅谈Python traceback的优雅处理

刚接触Python的时候，简单的异常处理已经可以帮助我们解决大多数问题，但是随着逐渐地深入，我们会发现有很多情况下简单的异常处理已经无法解决问题了，如下代码，单纯的打印异常所能提供的信息会非常有限。 def func1(): raise Exception("--func1 exception--") def main(): try: func1() except Exception as e: print e if __name__ == '__main__': main() 执行后输出如下： –func1 exception– 通过示例，我们发现

这段代码中的报错信息显示，`plt.subplot` 函数的第一个参数传递了 `-1`，而实际上行数必须是正整数。因此，需要检查该函数调用的参数是否正确。建议将 `plt.subplot(-1, 4, i+1)` 改为 `plt.subplot(2, 2, i+1)`，表示将图形分成 2 行 2 列，总共 4 个子图，第 `i+1` 个子图。这样就能避免该报错。
