Comparing Dates in Python
Determining the order or equality of two dates is a common task in programming. In Python, the datetime module provides powerful tools to facilitate date comparison.
To compare two dates, utilize the comparison operators such as < (less than), > (greater than), <= (less than or equal to), >= (greater than or equal to), and == (equality). For instance, to check if the current date (accessible via datetime.now()) is later than a specific past date, employ the operator <.
For more complex comparisons involving durations or time spans, utilize the timedelta class. By subtracting one date from another, you can obtain a timedelta object representing the interval between them. This interval can then be compared using the same operators mentioned earlier.
Example:
Suppose you have a list of holiday dates stored in a file named holiday.txt. To automate the process of notifying an administrator when the current date exceeds the last holiday date, you can follow these steps:
This approach ensures that your system stays updated with the latest holiday information, preventing potential issues related to outdated holiday data.
