减少小型python脚本中条件的数量

我一直在开发一个小程序。 它的工作原理非常完美，但我想让代码稍微小一点

import time, math 
name= input("Enter Your Name: ")
age= int(input("Enter Your Age: "))
end= "th"
if age == 3 or age == 13 or age == 23 or age == 33 or age == 43 or age == 53 or age == 63 or age == 73 or age == 83 or age == 93:
 end= "rd"

if age == 2 or age == 22 or age == 32 or age == 42 or age == 52 or age == 62     or age == 72 or age == 82 or age == 92:
 end= "nd"

print ("Your Name Is "+ name + ", You Are " + str(age) + " Years Old.")
print ("Hi " + name + ", Happy " + str(age) + end + " birthday!")
time.sleep(5)

我想用一种更简单的方法将“end”更改为其他值，而不必全部写入。我可以让它从3开始，然后对所有10个以上的值执行此操作。

使用：

或者使用口述：

ends = {2: "nd", 3: "rd"}
end = ends[age % 10]

您还可以使用默认值：

ends = {1: "st", 2: "nd", 3: "rd"}
end = ends.get(age % 10, "th)

您可以尝试以下方法：

if int(age[-1]) == 3:
   end= "rd"

if int(age[-1]) == 2:
   end= "nd"

提取第十位的数字。那就直截了当了。虽然这个问题属于SO的

codereview

对应问题

import time, math
name= input("Enter Your Name: ")
age= int(input("Enter Your Age: "))

tenth_place = age % 10
if tenth_place == 3:
    end = "rd"
elif tenth_place == 2:
    end = "nd"
else:
    end = "th"

print ("Your Name Is "+ name + ", You Are " + str(age) + " Years Old.")
print ("Hi " + name + ", Happy " + str(age) + end + " birthday!")
time.sleep(5)

可能不一定更短，但它可以工作（并保持第12和第13位正确）

谢谢大家，伙计们

我还发现了另一个缺陷并修复了它，这是我当前的代码。 谢谢

导入时间、数学
name=输入（“输入您的姓名：”）
年龄=整数（输入（“输入您的年龄：”）
end=“th”
如果年龄%10==3：
end=“rd”
elif年龄%10==2:
end=“nd”
elif年龄%10==1:
end=“st”
如果年龄<20岁且年龄>10岁：
end=“th”
打印（“你的名字是“+Name+”，你是“+str（年龄）+”岁。”）
打印（“嗨”+姓名+”，快乐“+str（年龄）+结束+“生日！”）
时间。睡眠（2）

谢谢，

Bilbo

请写一个更好地描述你的问题的标题。你应该环顾一下网站，看看如何写一个描述性的标题——你现在的标题不是特别清楚。另外，查看Python中的模运算符（提示：您可以用

age%10==3

）替换您的第一个检查。这里已经回答了这个问题：而且，您似乎遗漏了整个案例……好的，下次C.dlp感谢大家的回答时，我会告诉大家，它成功了perfectly@Bilbo你应该考虑接受这个答案，在这种情况下，谢谢大家的想法，
