You can use fractions to tackle computer science’s classic change-making problem, which you might encounter on a job interview. It asks for the minimum number of coins to get a certain amount of money. For example, if you consider the most popular coins of the US dollar, then you could...
Python’s datetime module provides the timedelta class, which you can use to add or subtract a certain number of days from a date. Here’s how you can use it:from datetime import datetime, timedeltacurrent_date = datetime.now()new_date = current_date + timedelta(days=5)print(new_date)...
