Python用字典实现switch函数

month_dict = {
  
  "01": "Jan", "02": "Feb", "03": "Mar", "04": "Apr",
              "05": "May", "06": "Jun", "07": "Jul", "08": "Aug",
              "09": "Sep", "10": "Oct", "11": "Nov", "12": "Dec"}

date = “2018-05-22”

day = date[8:]
month = month_dict[date[5:7]]
year = date[0:4]

print(month + " " + day + ", " + year）

输出结果：

May 22, 2018
