Reading and Writing Files in Python.
JSON is an acronym standing for JavaScript Object Notation. The json library in python can parse JSON from strings or files. The library parses JSON into a Python dictionary or list. We come across various circumstances where we receive data in json format and we need to send or store it in csv format.

This tutorial shows how easy it is to use the Python programming language to work with JSON data.. It is easy for humans to read and write. It is easy for machines to parse and generate.
Python is sometimes described as an object-oriented programming language. This can be somewhat misleading and needs to be clarified. In Python, everything is an object, and can be handled as such. This is what is meant when we say, for example, that functions are first-class objects.
Phillip March 1, 2015 at 11:29 am. I have a strong feeling you are trying to run this using Python 2. The super() method was introduced in Python 3. Depending on how you have Python installed, running python at the command line could open a 2.x.x version and running python3 could open a 3.x.x version. It really depends on how you have things configured.
Writing a lexer and parser is a tiny percentage of the job of writing a compiler. Using a generator will take up about as much time as writing one by hand, and it will marry you to the generator (which matters when porting the compiler to a new platform).
Writing to a string. Sometimes you won’t want to write your SeqRecord object(s) to a file, but to a string. For example, you might be preparing output for display as part of a webpage. If you want to write multiple records to a single string, use StringIO to create a string-based handle.
The first step to writing a parser is to figure out what's in the file and what you want from the file. I usually start by looking at files in the given format and get a feel for what's in them. In this case it looks like a FASTA file contains a set of sequence records and each sequence record has a title line (also called a description line or a comment line) and a sequence, which may be.
