Question

我制作了一个程序，从Google Sheet流程中获取一条记录，然后将其删除，依此类推。如果我更新Google表格，那么程序将在下一个循环中扣除记录并对其进行处理，然后删除，但它只运行1或2小时，然后程序出错：

我可以在程序中添加什么，以便我的程序永不停止？

                    pass
            except:

                pass

        print 'Row '+str(i)+' Successfully Updated. \n'
    time.sleep(120) #while loop sleep for 20minuts

这是我得到的错误：

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "<string>", line 56, in parse
  File "<string>", line 35, in parse
cElementTree.ParseError: no element found: line 1, column 0

Answer 1

由于某种原因cell = workSheet.find(b)失败。可能是那里的坏数据;没有看到输入，这是任何人的猜测。

由于您已经知道了行号，因此您可以通过简单地跟踪您正在搜索的列并在复制数据后最终调用cell = workSheet.find(b)来避免使用workSheet.update_cell(i, col, '')。
