老师，请问下为何我只要将run_main方法中添加了这段代码，他就会提示我的keyError错误。下面是我的run_main方法的代码，如果不添加这段代码，就可以正常运行。。。你看下是我哪里出现了问题。

class RunMain:
def run_case(self):
rows = excel_data.get_row()
for i in range(rows):
data = excel_data.get_row_value(i+2)
is_run = data[2]
if is_run == ‘yes’:
url = data[5]
excepect_method = data[11]
excepect_result = data[12]
head = data[8]
if head == ‘yes’:
head = get_header()
method = data[6]
is_depend = data[3]
data = json.loads(data[7])
if is_depend:
is_depend_key = data[4]
depend_data = get_data(is_depend)
data[depend_data] = depend_data
res = request.run_main(method=method,url=url,data=data,header=head)
print(res)
code = res[‘state’]
message = res[‘success’]
message = str(message)
code = res[‘state’]
message = res[‘success’]
message = str(message)
if excepect_method == “mec”:
config_message = handle_result(url, “state”)
config_message1 = handle_result(url, “success”)
if code == config_message and message == config_message1:
excel_data.excel_write_data(i + 2, 14, “通过”)
else:
excel_data.excel_write_data(i + 2, 14, “失败”)
excel_data.excel_write_data(i + 2, 15, json.dumps(res))

     if excepect_method == "errorcode":
         if code == excepect_result:
            excel_data.excel_write_data(i + 2, 14, "通过")
         else:
            excel_data.excel_write_data(i + 2, 14, "失败")
            excel_data.excel_write_data(i + 2, 15, json.dumps(res))

      if excepect_method == "json":
         if code == "1":
            get_result = get_result_json(url, "data")
            reslut = handle_result_json(res["data"], get_result)
         if reslut == True:
            excel_data.excel_write_data(i + 2, 14, "通过")
         else:
            excel_data.excel_write_data(i + 2, 14, "失败")
            excel_data.excel_write_data(i + 2, 15, json.dumps(res))

if name == ‘main’:
run = RunMain()
print(run.run_case())
