How many days have passed since the beginning of the year?

In this case personally, I would prefer to maintain clean & reusable code.

Here's a more verbose version

Code
Diff
  • from datetime import datetime

def count_days(since: datetime, to: datetime) -> int:
    return (to - since).days + 1

def days(month: int, day: int) -> int:
    since = datetime(day=1, month=1, year=2022)
    to = datetime(day=day, month=month, year=2022)

    return count_days(since, to)
    • days=lambda m,d:(__import__("datetime").datetime(2022,m,d)-__import__("datetime").datetime(2022,1,1)).days + 1
    • from datetime import datetime
    • def count_days(since: datetime, to: datetime) -> int:
    • return (to - since).days + 1
    • def days(month: int, day: int) -> int:
    • since = datetime(day=1, month=1, year=2022)
    • to = datetime(day=day, month=month, year=2022)
    • return count_days(since, to)
