有没有一种方法可以从类中的用户输入进行追加？

Question

有没有一种方法可以实现用户输入来在我定义的类中创建一个新条目？你知道吗

class Pulsar:
   'Collective base of all Pulsars'
   pulsarCount = 0

   def __init__(self, name, distance):
      self.name = name
      self.distance = distance
      Pulsar.pulsarCount += 1

   def displayCount(self):
     print( "Total Pulsars %d" % Pulsar.pulsarCount)

   def displayPulsar(self):
      print( "Name : ", self.name,  ", Distance: ", self.distance)

"This creates the first object"
pulsar1 = Pulsar("B1944+17", "979 Lightyears")
"This creates the second pulsar in the class"
pulsar2 = Pulsar("J2129-5721", "1305 Lightyears")
pulsar1.displayPulsar()
pulsar2.displayPulsar()
print( "Total Pulsars %d" % Pulsar.pulsarCount)

我希望用户能够输入自己的名称/距离，并将其附加到我当前定义的变量中。你知道吗

取决于你对脉冲星对象的处理，一个类可能是杀伤力过大。你知道吗

class Pulsar:
    def __repr__(self) -> str:
        return f'Pulsar({self.name!r}, {self.distance!r})'

    def __init__(self, distance: str, name: str) -> None:
        self.name: str = name
        self.distance: str = distance


num_pulsars_input = int(input('How many pulsars do you wish to create: '))

pulsar_list = []

for _ in range(num_pulsars_input):
    curr_p_name = input('Enter pulsar name: ')
    curr_p_dist = input('Enter pulsar distance: ')
    curr_p = Pulsar(curr_p_name, curr_p_dist)
    pulsar_list.append(curr_p)

print(pulsar_list)
