如何解决如何为用户输入的密钥调用字典? 将 tile_size 的键声明为 //放弃 month_dict 循环从month_dict[month]中移除for和for的声明
我想拨打给定的月份号码。如果用户输入 1 等,我希望输出类似于“一月的天数是 30”。
while True:
month_dict = {
"1": "January","2": "February","3": "march","4": "April","5": "May","6": "June","7": "July","8": "August","9": "September","10": "October","11": "November","12": "December"
}
month = int(input("Enter the number of month:"))
def number_of_date(month):
for value in month_dict.items():
if month in [1,3,5,7,8,10,12]:
print("Number of days in",value,"is 31!!!")
elif month in [4,6,9,11]:
print("Number of days in","is 30!!!")
elif month == 2:
print("Number of days in","is 28!!!")
else:
print("There is not a month like that.. Check your writing!")
number_of_date(month)
解决方法
给你。只需稍微重新排序和修复即可。基础非常扎实。
month_dict = {
1: "January",# removed "" around the numbers,because inputs are immediately converted to ints.
2: "February",3: "March",4: "April",5: "May",6: "June",7: "July",8: "August",9: "September",10: "October",11: "November",12: "December"
}
def number_of_date(month): # removed for loop. You only need to print it once
if month in [1,3,5,7,8,10,12]:
print("Number of days in",month_dict[month],"is 31!!!") # month_dict[month] returns the correct name.
elif month in [4,6,9,11]:
print("Number of days in","is 30!!!")
elif month == 2:
print("Number of days in","is 28!!!")
else:
print("There is not a month like that.. Check your writing!")
while True: #while loop only around function call. No need to redefine functions every time
month = int(input("Enter the number of month:"))
number_of_date(month)
#notice that your program will never end. Maybe loop only while month != -1. So -1 can be used to exit the program.
,
将 tile_size
的键声明为 //
主要问题是 column = mouse_pos[0] // tile_size
row = mouse_pos[1] // tile_size
中的键是字符串。如果您将它们更改为整数:
month_dict
然后您可以简单地使用 int
获取与其编号相关联的月份名称。
放弃 month_dict
循环
丢失函数内的 month_dict = {
1: "January",2: "February",12: "December"
}
将使其打印单个最终结果。
从month_dict[month]
中移除for
和for
的声明
最后,还要考虑这样做以避免一遍又一遍地声明相同的值。
完整代码如下:
month_dict
我想就是这样!
