我编写了一个程序，可以根据用户的出生年月日输入来计算用户的年龄。它对每个用户输入使用while循环，并对每个可能的错误使用continue命令。代码在控制台中正常工作，但我正在努力使它在一个不和谐机器人内工作，因为每当有人进入一些会保证错误的东西时，错误就会无限循环，我不知道如何绕过它，同时也使程序按预期工作。
下面是修改前的完整代码:
from datetime import datetime
current_time = datetime.now()
print('Welcome to the Age Calculator!nPlease enter the following information to have your age precisely calculated:n')
while True:
try:
year = int(input('What is your birth year?n'))
if year < current_time.year and year >= current_time.year - 100:
break
else:
print('Error: You must enter a valid year.n')
continue
except ValueError:
print('Error: You must enter a whole number.nFor example: 1996n')
continue
monthConversions = {'january': 1,'february': 2, 'march': 3, 'april': 4, 'may': 5, 'june': 6, 'july': 7, 'august': 8, 'september': 9, 'october': 10, 'november': 11, 'december': 12}
while True:
in_str = input('What is your birth month?n')
in_str = monthConversions.get(in_str.lower(), in_str)
try:
month = int(in_str)
if month > 12 or month < 1:
raise ValueError
break
except ValueError:
print('Error: You must enter the full name of the month or a whole number from 1 to 12.n')
while True:
try:
day = int(input('What is your birth day?n'))
if month in [1, 3, 5, 7, 8, 10, 12] and day < 32 and day > 0:
break

break
else:

continue
except ValueError:
print('Error: You must enter a whole number.nFor example: 25')
continue
print('nYour birth date is ' + str(day) + '.' + str(month) + '.' + str(year) + '.')
ageyear = current_time.year - int(year)
if int(month) < current_time.month:
ageyear = current_time.year - int(year)
elif int(month) >= current_time.month:

bot.run(token)
如果用户输入正确的年、月和年龄，它将按预期工作，但如果用户出现任何错误，它将开始循环错误消息。我试着让循环的每个继续部分都是一个中断，但这不起作用，它只会让错误通过。
如果用户输入月份的名称而不是月份的数字，它也不能工作，尽管这部分在原始代码中工作。
任何帮助/建议都是感激的!
下面是一个固定代码的示例，它在执行命令之前检查条件以防止任何循环:
