Question

我正在使用python中的phonenumbers模块试图找出一个数字载体。输入数字后，它不会打印任何内容。这是我的密码

import phonenumbers 

import phonenumbers.carrier 

num_object = None 

while num_object is None: 
    try: 
        num = input("phone number:         ") 
        num_object =         phonenumbers.parse("+1     {}".format(num), region="US") 
except Exception as error: 
    print("ERROR: {}".format(error)) 
      
carrier =     phonenumbers.carrier.name_for_number(n.   um_object, "en") 
print(carrier)

输出为空。 我如何让它说出承运人的名字

Answer 1

从文档中：

>>> from phonenumbers import carrier
>>> ro_number = phonenumbers.parse("+40721234567", "RO")
>>> carrier.name_for_number(ro_number, "en")
'Vodafone'
