    errmsg = ""
    for i in range(len(fieldNames)):
        option = fieldNames[i].strip()
        if fieldValues[i].strip() == "" and option[0] == "*":
            errmsg += ('【%s】为必填项。\n\n' % fieldNames[i])

6. If there are fewer values than names, the list of values is padded with empty strings until the number of values is the same as the number of names.
   
7. If there are more values than names, the list of values is truncated so that there are as many values as names.
   
8. Returns a list of the values of the fields, or None if the user cancels the operation.

Returns a list of the values of the fields,

如果填写了返回的是一个列表，取消了返回None。所以在for前面语句，是在选择取消以后跳出while循环的作用。
for循环里面就是对每一个字段的值进行检查，就是列表切片取出，然后去除空格以后和空格对比。
