How to add one day to a date?

There are a few different ways to add one day to a date. Here are a few options:

  1. If you're working with the datetime module in Python, you can use the timedelta class to add one day to a date. For example:
from datetime import datetime, timedelta

date = datetime(2020, 1, 1)
new_date = date + timedelta(days=1)
print(new_date)  # Output: 2020-01-02 00:00:00
  1. If you just want to add one day to a date represented as a string, you can parse the string into a datetime object, add one day using the method above, and then format the date back into a string. For example:
from datetime import datetime, timedelta

date_str = "2020-01-01"
date = datetime.strptime(date_str, "%Y-%m-%d")
new_date = date + timedelta(days=1)
new_date_str = new_date.strftime("%Y-%m-%d")
print(new_date_str)  # Output: 2020-01-02
  1. If you just want to add one day to a date represented as a string, and you don't need to do any other date parsing or manipulation, you can simply extract the year, month, and day from the string, add one to the day, and then create a new date string. For example:
date_str = "2020-01-01"
year, month, day = map(int, date_str.split("-"))
day += 1
new_date_str = f"{year:04d}-{month:02d}-{day:02d}"
print(new_date_str)  # Output: 2020-01-02
