💡 Problem Formulation: Python developers often need to write byte data directly to a binary file. This task is common when handling binary formats or low-level file interaction. For instance, you might have a list of bytes, like [0x15, 0x1C, 0xFE], and want to write it as binary data to a file named “output.bin”. The … Read more
💡 Problem Formulation: In many programming scenarios, there’s a need to write binary data, such as a list of bytes, to a file. This could be for purposes such as persisting serialized data or storing multimedia content. For instance, we might want to convert a list of byte values [112, 121, 116, 104, 111, 110] … Read more
💡 Problem Formulation: In various computing scenarios, there is a need to perform an exclusive OR (XOR) operation on a list of bytes. This bitwise operation takes two bit patterns of equal length and performs the logical XOR operation on each pair of corresponding bits. For example, given a list of bytes [0b0101, 0b1100], performing … Read more
💡 Problem Formulation: In Python, dealing with dates and times is a common task. One often needs to modify a datetime object by adding a specific amount of time to it, such as several hours, minutes, or even microseconds. For example, given the input datetime.datetime(2023, 3, 14, 9, 26) one might want to add 90 … 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
💡 Problem Formulation: When working with time data in Python, you might encounter the need to round time objects to the nearest 10-minute mark. For instance, if you have an input time of 12:43, you’d expect the rounded output to be 12:40. Conversely, an input of 12:46 should round to 12:50. In this article, we’ll … Read more
