![]() ![]() They are all in the "Central European Time" timezone. Print(today.timestamp()) # 1577104357.558527īecause it is so common to get the timestamp of right now, we can use the time module to get it more easily: import timeĪ timezone is a region where the same standard time is used.įor example, a lot of Western Europe uses the same standard time-Spain, France, Italy, Germany, etc. To get a timestamp you can call the timestamp() method of any datetime object: import datetime The timestamp for "2nd January, 1970, at midnight" would be 86400: the number of seconds in one day. We use timestamps because it is easier to work with a single number (albeit large) than with many numbers each describing a different measurement. The same format strings as we used for strftime can be used in strptime What is a timestamp?Ī timestamp is the number of seconds that have passed since 1st January, 1970, at midnight. User_date = input("Enter today's date: ") strptime to parse a date string into a datetime object: import datetime Clearly this string is in the format "day-month-year". Very similarly to printing dates with a specific format, we can read in dates with a specific format.įor example, let's say your user gives you a string describing today's date: 23-12-2019. This is a good reference for all different things you can pass to strftime: ( ). import datetimeĭoing this does not modify the today object at all, it just creates a string representing the date or time as dictated by the "format string" passed. strftime(), which stands for " string format time". Maybe you only want to print out the date portion. Sometimes you may want more flexibility regarding how you print it out. You can print dates or convert them to strings by using the built-in str() function, so that they'll be shown in this format: import datetime All other arguments will be converted to those (e.g. You can use timedelta with these arguments:īut the object itself will only store days, seconds, and microseconds. A "delta" in mathematics means a "change", so that's where the name comes from. Instead, when you want to change a date-for example by adding a few days to it-we use the timedelta class. For example, what should happen if you add "today" to "today"? import datetime ![]() You can't add two dates together, as that seldom makes sense. This can be unnecessary, but when dealing with computers it can sometimes be useful. Notice that when we're doing this, we get microseconds as well as the other time measures. Also, it does now allow us to give it timezone information (more on that later!) You can also use () to get the current time and date, but it can sometimes be less precise. How to get today's dateīecause getting today's date is so common, the datetime class comes with a method you can use to get a new datetime object for today's date: import datetime This is how we can compare two dates, for example to tell whether something happened in the past. Here we would print False because today is in the past, relative to tomorrow. ![]() In addition to storing data about the specific point in time, it also has methods that help us interact with or process that data in a way that makes sense.įor example, given two datetime objects you can compare them to see which one is further into the future. With all that information, we can use a datetime object to refer to one particular moment in time. Information such as year, month, day, hour, minute, and second. ![]() Put simply, a datetime object is one that stores information about a specific point in time. This usually means that we work with the datetime class inside the datetime module-somewhat confusing, but that's why you'll normally see things like datetime.datetime when looking at Python code that uses this. Inside the module we can find a few classes, but the most used ones are datetime and timedelta. The datetime module is a built-in module in Python that allows us to work with dates and times easily. ![]()
