python将字符串类型改成日期类型

将字符串类型的'2019-03-14'改成date类型，如下：

import datetime

b = datetime.date(*map(int,'2019-03-14'.split('-')))
print(b,type(b))

 将datetime类型转成str

form datetime import datetime

str_date = datetime.now().strftime("%Y-%m-%d") 

将str类型转成datetime

form datetime import datetime

start_date = datetime.strptime("2019-04-15", "%Y-%m-%d")
