💡 Problem Formulation: When working with dates in Python, it’s common to need to check whether a given date falls on a weekend. This is crucial for applications that require different logic for weekdays versus weekends, such as scheduling software or automated reports that only run on business days. For example, given a date input, … Read more
💡 Problem Formulation: You want to sort a Python dictionary whose keys are datetime objects to organize entries chronologically. For instance, given a dictionary {datetime(2021, 3, 1): “a”, datetime(2021, 2, 1): “b”} the goal is to sort it to get {datetime(2021, 2, 1): “b”, datetime(2021, 3, 1): “a”}, arranging the keys from the earliest to … Read more
💡 Problem Formulation: When working with Python’s datetime module, developers often need to display the current datetime in a specific format. For example, one might need the current date and time as ‘YYYY-MM-DD HH:MM:SS’ or just the date ‘YYYY-MM-DD’. This article explains various methods to format the output of the datetime.now() function suitably for different … Read more
💡 Problem Formulation: In Python programming, you may encounter the need to modify a datetime object by adding an hour. Whether you’re dealing with log timestamps, scheduling events, or simply manipulating time, the requirement is clear: given a datetime object representing a certain moment, how can you calculate the time one hour later? For instance, … Read more
💡 Problem Formulation: Manipulating date and time is a common task in software development. For example, you might need to add a specific number of seconds to a datetime object in Python to calculate an expiry time or to delay a particular action. The input would be a datetime object and the number of seconds … Read more
💡 Problem Formulation: When working with file operations in Python, it’s a common requirement to name files with a timestamp. This ensures a unique filename and can preserve the history of file creation. The problem at hand involves appending a datetime string to a file’s base name. For instance, given an input filename ‘report.csv’, we … Read more
💡 Problem Formulation: Often, Python developers encounter the need to manipulate dates and times, including adding a specific duration to the current moment. For instance, you may want to calculate what the datetime will be in 2 hours, 30 minutes from now as an input, and obtain the future datetime as your output. This article … Read more
Converting Python Date-Time to Just Date 💡 Problem Formulation: You’ve got a Python datetime object and you want to strip away the time part, leaving you with just the date. For example, you might have a datetime like 2023-04-01 14:30:00 and you want to get just 2023-04-01. Let’s explore various methods to achieve this. Method … Read more
💡 Problem Formulation: GPS timestamps are measured from a different epoch and may not account for leap seconds, making them differ from Coordinated Universal Time (UTC). This article aims to solve the problem of converting GPS time, typically represented in weeks and seconds since January 6, 1980, to the more widely-used UTC format. For example, … Read more
💡 Problem Formulation: When working with dates and times in Python, a common task is to convert ISO formatted time strings to Unix epoch time. This article demonstrates how to translate an ISO 8601 datetime string such as “2021-12-25T12:34:56+0000” into the equivalent epoch timestamp, a number representing the total seconds since January 1, 1970 (UTC), … Read more
💡 Problem Formulation: When working with JSON data in Python, dates and times are commonly represented as strings. However, for date manipulations and comparisons, it’s essential to convert these string representations into proper Python datetime objects. Assume we’re given a JSON string formatted as { “timestamp”: “2023-03-15T12:45:00Z” } and we want to convert the timestamp … Read more
💡 Problem Formulation: When working with times in Python, developers often need to convert local time to Greenwich Mean Time (GMT). For instance, you may have a local timestamp ‘2023-03-18 15:30:00’ and want to convert it to the equivalent GMT ‘2023-03-18 14:30:00’. This article will explore five methods to perform this conversion efficiently. Method 1: … Read more
