Python Programming Language
Python programming language is one of the most used programming languages, as it is used widely in the field of software and data analysis, web development, etc. It is said to be a user-friendly programing language, as the syntax for it is very simple to write and easy to understand for a beginner programmer. Python programming language is rich in libraries that can be imported easily and used to perform many different operations. In the year 1989, Guido van Rossum is the one who introduced python programming language. It is also used in web applications; web applications like the Django and Flask frameworks are created using python. Compared to any programming language, the syntax in python is much easier.
Python programming language is most widely used language in today’s technology. Many colleges and institutions have introduced python in their syllabus so that the students need to learn python. The biggest advantage of the python programming language is that it has a good collection of libraries widely used in machine learning, web frameworks, test frameworks, multimedia, image processing, and many more application. Python supports multiple programming paradigms, including object-oriented, imperative, functional, and procedural. The ISO 8601 date, time, and duration parsing is implemented in this module. Only the date and time formats mentioned in the ISO8601:2004 standard are used in the implementation. Anything that isn't specified there is assumed to be nonexistent and isn't an option.
The ISO 8601 date, time, and duration parsing is implemented in this module. Only the date and time formats mentioned in the ISO8601:2004 standard are used in the implementation. Anything that isn't specified there is assumed to be nonexistent and isn't an option.
For instance, 2 digit years are never mentioned in ISO8601:2004.Therefore, this module is not intend to support years with two digits. (While it is possible that it is still valid as an ISO date because it is not expressly prohibited.) Another illustration is that a time should be read as local time rather than UTC when no time zone information is provided for it.All potential ISO 8601 dates and times cannot be converted because this module only converts ISO 8601 dates and times to normal Python data types like date, time, datetime, and timedelta. For instance, the Python date and datetime classes do not support dates from before 0001-01-01.
Additionally, microseconds are the only form of fractional seconds. That implies that the parser will round nanoseconds to microseconds if it is found. Since timedelta does not support years and months but ISO 8601 allows for it, this module offers a Duration class that may be used almost like a timedelta object (with some limitations). A Duration object can be changed into a timedelta object, though.
For all supported data types, ISO formatting techniques are also available. A format parameter can be used with any xxx isoformat method. The enlarged ISO 8601 format is always the default. The format is the same as what datetime uses. isoformat:
The time isoformat command is used to generate ISO time strings in the hh:mm:ssZ format by default.
Create ISO date strings with the default format of yyyy-mm-dd using date isoformat.
Create ISO date-time strings with the default format of yyyy-mm-ddThh:mm:ssZ using datetimeisoformat.
To construct ISO duration strings with the default format PnnYnnMnnDTnnHnnMnnS, use the duration isoformat function.
Creates ISO time zone strings using the hh:mm format by default.
A re-implementation of Python's strftime that only supports the format strings that can also be used for dates before 1900 is called strftime. Additionally, this function is capable of formatting instances of DateTime and Duration
The ISO 8601 standard states that a number of date and time representations are invalid, however the parser accepts them.
- This parser supports both basic and extended formats for date and time combined. For instance, the date could be in basic format, while extended format for the time is acceptable. Short dates and times may also be used in date-time strings.
- The first day is picked for dates that are not complete. For instance, the 19th century yields the date 1901-01-01.
- Negative Duration and timedelta value do not yet have complete support.
