用户输入错误后，我希望能够重新启动程序

Question

我正在使用python模块pypokedex编写一个程序，以编写一个询问口袋妖怪名称和生成方式的程序，并在其中展开一个https://www.serebii.net/页面。但是，如果用户拼写错误的神奇宝贝，它只会出错并关闭程序。我希望它重新启动程序。

我也有它，如果代码成功，它仍然会循环，问题出在何时失败（再次，这只是用户拼写错误的问题）

此Asking the user for input until they give a valid response不起作用的原因是因为我需要输入特定的单词，而不是一定范围的数字。

import pypokedex
import webbrowser

while 1==1:

    name = input("What pokemon are you searching for? ")

    p = pypokedex.get(name = name)

    zero = 3-len(str(p.dex))

    if(zero == 2):
        num = "00" + str(p.dex)

    if(zero == 1):
        num = "0" +str(p.dex)

    if(zero == 0):
        num = str(p.dex)


    ngen = input("What generation number are you looking for? ")

    if(ngen == str(1)):
        gen = "pokedex"

    if(ngen == str(2)):
        gen ="pokedex-gs"

    if(ngen == str(3)):
        gen = "pokedex-rs"

    if(ngen == str(4)):
        gen = "pokedex-dp"

    if(ngen == str(5)):
        gen = "pokedex-bw"

    if(ngen == str(6)):
        gen = "pokedex-xy"

    if(ngen == str(7)):
        gen = "pokedex-sm"

    url = "https://www.serebii.net/" +  str(gen) + "/" + str(num) + ".shtml"\


    webbrowser.open(url , 2)
