我现在正在使用什么 在need年检查之后,我需要帮助显示奥运会的举办地
def isLeap(year):
# your code (note comment under original post for the statement order)
if(year % 4 == 0 and year % 100 != 0):
return True
elif(year % 400 == 0):
return False
elif(year % 100 == 0):
return True
else:
return False
# just write every pair of year and city in this format
host = host = {1986 : "Athens",1900 : "Paris",1905 : "St.louis",1908 : "London",1912 : "Stockholm",1920 : "Anstwerp",1924 : "Paris",1928 : "Amsterdam",1932 : "Los Angeles",1936 : "Berlin",1948 : "London",1952 : "Helsinki",1956 : "Melbourne-Stockholm",1960 : "Rome",1964 : "Tokyo",1968 : "Mexico",1972 : "Munich",1976 : "Montreal",1980 : "Moscow",1984 : "Los Angeles",1988 : "Seoul",1992 : "Barcelona",1996 : "Atlanta",2000 : "Sydney",2004 : "Athens",2008 : "Beijing",2012 : "London",2016 : "Rio",2020 : "Tokyo",2024 : "Paris",2028 : "LA"}
userInput = int(input())
if(isLeap(userInput)):
print(host[userInput])
非常感谢您的帮助, 谢谢
答案 0 :(得分:1)
您可以使用与相应城市相关联的奥林匹克运动会来存储所有年份,如下所示:
host = {2004 : "Athens", 2008 : "Beijing", 2012 : "London", 2016 : "Rio"}
然后,一旦您的function年函数将年份评估为a年,只需访问词典中该年键的值即可。
>>> print(host[2012])
London
完整的解决方案如下所示:
def isLeap(year):
# your code (note comment under original post for the statement order)
if(year % 4 == 0 and year % 100 != 0):
return True
elif(year % 400 == 0):
return True
elif(year % 100 == 0):
return False
else:
return False
# just write every pair of year and city in this format
host = {2004 : "Athens", 2008 : "Beijing", 2012 : "London", 2016 : "Rio"}
userInput = int(input("Enter Year: "))
if(isLeap(userInput)):
print(host[userInput])
