![]() ![]() With these in your toolbox you're 90% of the way toward solving all of the date and time challenges in your next python project. So now you are armed with the five most useful datetime tricks. Be prepared to perform some twisted conversions in order to get all of the data you ingest into that format. However, be warned that there exist a multitude of a date formats in the wild. I highly recommend whenever you are given the choice to format your dates in this way for ease of interpretability and compatibility. (An international standard, ISO 8601, established this in 1988.) In this format, for example, Jwould be ''. In this code snippet, '%Y' represents the year, '%m' the two digit month, and '%d' the two digit day.Īs a side note, there is actually one correct way to represent years, months, and days in dates: 'YYYY-MM-DD'. When making a conversion in either direction, we have to supply a string that specifies the format. To do this, we use the strptime() and strftime() functions. It is also helpful when we want to expose our datetime object to a user, or export it to a text file. This is particularly helpful when we are ingesting data from a text file, and want to turn text dates into datetime objects. New_datetime = (ĭatestr = new_datetime.strftime('%Y-%m-%d')įinally, we come to trick number five, which is converting a date to and from a string. The datetime() class requires three parameters to create a date: year. Example: import datetime epochtime 30256871 datetime (epochtime) print (datetime) In this example I have imported the datetime package and taken the variable as epoch time and value to the variable like the number of seconds and used datetime. # Pass a date string and a code for interpreting it. To create a date, we can use the datetime() class (constructor) of the datetime module. Let us see with the below example on Python epoch to DateTime. The first datetime references the package, the second datetime references the module, and combine() is a function within that module. So when we combine our date and time, we call it with the apparently redundant datetime.datetime prefix. Datetime is the name of the package, a module within the package, and the object. because Python calls the platform C librarys strftime() function. We use the combine() function, and pass it the date object and the time object that we want to build our datetime out of.īecause of the naming convention, calls to datetime can be confusing. The datetime module supplies classes for manipulating dates and times in both simple. Then we create a date by passing the year, month, and day.Ĭreating a datetime is straightforward. Because we didn’t supply the second or the microsecond, these are assumed to be zero. We start by creating a time, passing it the hour of 7 and the minute 0. The first trick for working with datetimes is to be able to create them by combining date and time objects.
