Python data Type - Datetime
자주 사용하게 되지만, 자주 헷갈리는 Python의 자료형에 대해서 정리를 해 나가겠습니다.
오늘은 Datetime입니다.
주어진 String값을 DateTime형식으로 바꾸기: strptime
Example 1: string to datetime object
|
from datetime import datetime
date_string = "21 June, 2018"
print("date_string =", date_string) print("type of date_string =", type(date_string))
date_object = datetime.strptime(date_string, "%d %B, %Y")
print("date_object =", date_object) print("type of date_object =", type(date_object)) |

date_string = 21 June, 2018 |
Example 2: string to datetime object
|
from datetime import datetime dt_string = "12/11/2018 09:15:32" # Considering date is in dd/mm/yyyy format dt_object1 = datetime.strptime(dt_string, "%d/%m/%Y %H:%M:%S") print("dt_object1 =", dt_object1) # Considering date is in mm/dd/yyyy format dt_object2 = datetime.strptime(dt_string, "%m/%d/%Y %H:%M:%S") print("dt_object2 =", dt_object2) |

dt_object1 = 2018-11-12 09:15:32 |
