![]() Using strptime() Format Tokens to Convert String to Different Datetime Format August is the 8th month, and is zero-padded to 08). Note: All of these tokens, except the year, are expected to be zero-padded (i.e. Some of the commonly used ones, that we've also used earlier are: The list of supported tokens is extensive enough to enable various formatting. It's worth taking a moment to understand format tokens - the "%Y-%m-%d %H:%M:%S.%f" from before.Įach token represents a different part of the date-time, like day, month, year, day of month or week, etc. As you can see from the output, it prints the 'date' and 'time' part of the input string! Format Tokens Since this is a datetime object, we can call the date() and time() methods directly on it. The returned datetime value is stored as date_time_obj. In our example, " 10:27:03.929149" is the input string and "%Y-%m-%d %H:%M:%S.%f" is the format of our date string. The return value is of the type datetime. ![]() Specifying the format like this makes the parsing much faster since datetime doesn't need to try and interpret the format on its own, which is much more expensive computationally. Here, we use the strptime() method, which accepts two arguments: Running it will print the date, time, and date-time: If our input string to create a datetime object is in the same ISO 8601 format or if you know the format you'll be receiving upfront, we can easily parse it to a datetime object: import datetimeĭate_time_str = ' 10:27:03.929149' # strptime(input_string, input_format)ĭate_time_obj = (date_time_str, '%Y-%m-%d %H:%M:%S.%f') When no custom formatting is given, the default string format is used, i.e. Running this code would result in: Current date/time: 10:27:03.929149 The date object holds the date, time holds the time, and datetime holds both date and time! import datetime The datetime module consists of three different object types: date, time, and datetime. In this guide - we'll take a look at how to convert a string date/time into a datetime object in Python, using the built-in datetime module, but also third-party modules such as dateutil, arrow and Maya, accounting for time zones. ![]() One of the most common sources of string-formatted datetimes are REST APIs that return agnostic strings, that we can then convert to other formats.Īdditionally - time zones are a common headache when it comes to working with datetime objects, so we'll need to think about that while converting too. However, to work with these dates and times in an arithmetic fashion (such as calculating time differences, adding or removing time, etc.) - we need to convert them to a datetime object. strftime() method.Data can be represented in various forms - and a convenient way to represent dates and times are strings. The following is an example code, to ISO date in string format using the. Here as we know that ISO format is YYYY-MM-DD so we convert it into this format by using the following format code- “%Y-%m-%dT%H:%M:%S.%f%z”. This string is converted into an ISO format string by using the. In this method, we get the current date and time from the local CPU by using the datetime.now() method. Where, format is used to specify the required format of the output. The syntax of strftime() is described below. We use time.gmtime(0) to get the epoch on a given platform. The epoch is January 1, 1970, 00:00:00 (UTC) on Windows and most Unix systems, and leap seconds are not included in the time in seconds since the epoch. It is also used to convert datetime to epoch.Įpoch is the starting point of time and is platform-dependent. Here we use the strftime() method to convert a string datetime to datetime. The strftime() method is provided by the datetime module in python. The output of the above code is as follows. In this example code, we get an ISO 8601 date in string format using the. This string is then converted into the ISO format by using the. In this method, we get the current datetime string by using the datetime.now() method which returns the current date and time in time format. Timespec(Optional parameter) − It is the format specifier for timespec. Sep(Optional parameter) − It is a separator character that is to be printed between the date and time fields. isoformat() method returns a string of date and time values of a python datetime.date object in ISO 8601 format. In this article, we will discuss how to get an ISO 8601 date in string format in python. To tackle this uncertainty of various formats ISO sets a format to represent dates “YYYY-MM-DD”.įor example, May 31, 2022, is represented as. ISO 8601 is a date and time format which helps to remove different forms of the day, date, and time conventions across the world. The ISO 8601 standard defines an internationally recognized format for representing dates and times.
