Python日期时间“无法调用int对象”

Question

from datetime import datetime, date
now = datetime.now()
print now.day()

How come when this code gives an error "'int' object is no callable", is there even a use to now.day()?

Answer 1

print now.day

is all you need

datetime.day is a property not a method and it returns the integer day ... so you are trying to call an integer when you add parentheses (ala 28() , which also clearly would not work)
