# 穷举法，硬来
# if s1 == "elephant" and s2 == "tiger":
#     print("win")
# elif s1 == "tiger" and s2 == "cat":
#     print("win")
# elif s1 == "cat" and s2 == "mouse":
#     print("win")
# elif s1 == "mouse" and s2 == "elephant":
#     print("win")
# 
# 
# elif s1 == "elephant" and s2 == "mouse":
#     print("lose")
# elif s1 == "tiger" and s2 == "elephant":
#     print("lose")
# elif s1 == "cat" and s2 == "tiger":
#     print("lose")
# elif s1 == "mouse" and s2 == "cat":
#     print("lose")

# 定义规则，用字典取键值

s1,s2 = map(str,input().split())

rule = {"elephant":"tiger","tiger":"cat","cat":"mouse","mouse":"elephant"}

if rule[s1] == s2:
    print("win")
elif rule[s2] == s1:
    print("lose")
else:
    print("tie")

我是穷举法，不问ai，我都想不到有字典定义规则这一套，太好使了。字典键值对，666
