InputPhoneContact没有len()

InputPhoneContact是一个函数或方法,它没有len()函数。len()函数用于返回一个对象的长度或元素个数,但是对于InputPhoneContact来说,它可能是一个自定义的函数或方法,不是一个内置的Python函数。

要解决这个问题,我们可以尝试以下几个步骤:

  1. 检查函数或方法的定义:查看InputPhoneContact的代码实现,确保它是一个正确定义的函数或方法。检查是否在函数或方法的定义中使用了len()函数,如果有,确认是否正确使用。
  2. 检查输入参数:确认InputPhoneContact函数或方法的输入参数是否正确。如果输入参数是一个字符串或列表等可迭代对象,可以尝试使用len()函数来获取其长度。
  3. 检查导入模块:如果InputPhoneContact函数或方法依赖于其他模块或库,确保已正确导入这些模块。有时候,len()函数可能是从其他模块中导入的,需要确保正确导入了这些模块。
  4. 检查函数或方法的返回值:确认InputPhoneContact函数或方法的返回值类型。如果返回值是一个字符串或列表等可迭代对象,可以尝试使用len()函数来获取其长度。

总之,要解决InputPhoneContact没有len()函数的问题,需要仔细检查函数或方法的定义、输入参数、导入模块以及返回值类型。根据具体情况进行调试和修复。

  • 九度OJ——1154Jungle Roads

    The Head Elder of the tropical island of Lagrishan has a problem. A burst of foreign aid money was spent on extra roads between villages some years ago. But the jungle overtakes roads relentlessly, so the large road network is too expensive to maintain. The Council of Elders must choose to stop maintaining some roads. The map above on the left shows all the roads in use now and the cost in aacms per month to maintain them. Of course there needs to be some way to get between all the villages on maintained roads, even if the route is not as short as before. The Chief Elder would like to tell the Council of Elders what would be the smallest amount they could spend in aacms per month to maintain roads that would connect all the villages. The villages are labeled A through I in the maps above. The map on the right shows the roads that could be maintained most cheaply, for 216 aacms per month. Your task is to write a program that will solve such problems. 输入: The input consists of one to 100 data sets, followed by a final line containing only 0. Each data set starts with a line containing only a number n, which is the number of villages, 1 < n < 27, and the villages are labeled with the first n letters of the alphabet, capitalized. Each data set is completed with n-1 lines that start with village labels in alphabetical order. There is no line for the last village. Each line for a village starts with the village label followed by a number, k, of roads from this village to villages with labels later in the alphabet. If k is greater than 0, the line continues with data for each of the k roads. The data for each road is the village label for the other end of the road followed by the monthly maintenance cost in aacms for the road. Maintenance costs will be positive integers less than 100. All data fields in the row are separated by single blanks. The road network will always allow travel between all the villages. The network will never have more than 75 roads. No village will have more than 15 roads going to othe
