关于python：for和in和enumerate，如果…… AHHHHHHH

for and in and enumerate and if … AHHHHHHH

我有一个涉及编程的学校项目。我在批处理和python之间转移，因为这对我来说最简单。

这是我用python编写的代码：

1

3
4
5

for i,x in enumerate(result):
if number in x:
print"Start of 1"
cursor.execute(insert1, (number))
cursor.execute(delete, (number))
f.close()
os.system("extracommands.bat 1")
print"Found Number"
else:
print"Start of 2"
cursor.execute(insert1, (number))
cursor.execute(insert2, (number))
cursor.execute(delete, (number))
f.close()
os.system("emailfine.py 1")
print"Finished 2"

我的问题是我在元组中找不到字符串。结果是，当有结果时，它会完美运行。但是当没有结果时，没有任何反应。

我怎么能克服这个？

先感谢您。

编辑：

在问我的问题时，我可能不够具体。

result变量实际上是使用fetchall()命令的MySQL执行结果。我的程序的整个代码是：
