💡 Problem Formulation: JSON data exchange format doesn’t natively support datetime objects from Python. Developers often need to serialize these objects into a string when saving to JSON and then deserialize them back into datetime objects upon retrieval. For example, one aims to convert datetime.datetime(2023, 4, 1, 15, 30) into a JSON-compatible string and vice … Read more
💡 Problem Formulation: You’re given a Python datetime object, and your goal is to convert it to a Julian day number. For instance, you want to transform the input ‘2023-03-23 12:00:00’ into the Julian day number ‘2459652’. This conversion is handy for astronomers, historians, and certain types of data scientists. Method 1: Using the datetime … Read more
💡 Problem Formulation: When working with dates and times in Python, you may often need to compare two datetime objects to determine which one is more recent, or “bigger”. For instance, comparing a user-inputted expiry date to the current date to validate if an offer is still valid. The desired output is a Boolean value … Read more
💡 Problem Formulation: When working with Python’s datetime objects, users often need to retrieve only the date part, excluding the time component. This is common when logging events, summarizing data, or comparing dates across records. The desired output would be to take a datetime object like datetime.datetime(2023, 4, 10, 18, 45) and extract just the … Read more
💡 Problem Formulation: Working with dates and times can be surprisingly complex. In particular, you might need to find out the calendar week number from a specific date in Python, such as converting ‘2023-04-12’ into the 15th week of the year. This article guides you through 5 different methods to achieve this, using Python’s powerful … Read more
💡 Problem Formulation: When working with dates in Python, a common requirement is to extract just the month and year from a datetime object. For instance, given the input datetime.datetime(2023, 4, 5), the desired output might be “April 2023”. This article will explore various methods to achieve this output efficiently. Method 1: Using strftime() Method … Read more
💡 Problem Formulation: When working with date and time in Python, it is a common task to compare datetime objects to determine which is earlier, later, or if they are equivalent. For example, given two datetime objects, datetime1 and datetime2, how do we ascertain whether datetime1 is before, after, or the same as datetime2? This … Read more
💡 Problem Formulation: When working with dates and times in Python, you may encounter situations where you need to isolate just the year from a datetime object. For instance, given the datetime ‘2023-04-01 15:23:00’, the desired output is simply ‘2023’. This article aims to explore various methods to achieve this extraction in a Pythonic way. … Read more
💡 Problem Formulation: Working with dates and times is common in many Python applications. For example, you might receive date information as a string from user input or a file and need to convert it to a datetime object for further manipulation. Given an input string like “2023-03-01”, how do we convert this into a … Read more
💡 Problem Formulation: When working with dates in Python, one might need to determine whether a specific year is a leap year. This is a common requirement for calendar applications, scheduling software, and any system that depends on accurate date calculations. The desired outcome is to input a year and receive a boolean output indicating … Read more
💡 Problem Formulation: In Python, handling datetime conversions across different time zones can be crucial for various applications. Specifically, converting local time to UTC (Coordinated Universal Time) is a common requirement. For instance, you have a datetime object representing local time, ‘2021-12-01 12:45:00’, and you want to convert it to UTC, resulting in ‘2021-12-01 17:45:00’ … Read more
💡 Problem Formulation: When working with dates and times in Python, a common requirement is to compute the difference between two datetime objects in seconds. For instance, given two datetime objects, start_time and end_time, we aim to find the number of seconds that have elapsed between these two points in time. Method 1: Using timedelta.total_seconds() … Read more
