To dump a Python object to JSON string, you can use the json.dumps() method of the built-in json module. The json.dump() paired method (without the "s") converts the Python object to JSON string and writes it to a file. By passing indent and sort_keys parameters to the json.dum...
This code illustrates how to use the `pickle.dumps()` and `pickle.loads()` functions in Python to serialize and deserialize data, respectively. The example involves a dictionary, showcasing the process of converting Python objects to byte streams and reconstructing the original data from those st...
Python's standard library even includes the json module, making it simple to parse and generate JSON without installing third-party packages. Why Does JSON Work Well With APIs? JSON’s ease-of-use and universally accepted structure are important for APIs because APIs are responsible for efficient...
We can also convert back these CSV files back to JSON files where the process is just opposite to the above process. Firstly we will read CSV data values and then write these data values in JSON format. In Python, we use DictReader() function to read CSV files and use the dump() and...
Concatenating Strings in Python To concatenate two strings in Python, you can use the "+" operator (only works with strings). To concatenate strings and numbers, you can use the operator "%". To concatenate list items into a string, you can use the string.join() method. The string.for...

To save objects to file in Python, we typically go through the following steps: Import thepickle module. Get a file handle in write mode that points to a file path. Usepickle.dumpto write the object that we want to save to file via that file handle. ...
I usually use xxd when looking for “fun” characters in files, and that tool is reversible for data files; you can hex dump a data file (or a text file) and then edit the hex dump, and then xxd to convert the patched file back to the original file format. The hexdump or other ...
abstract:This document provides how-to instructions for the pyparsing library, an easy-to-use Python module for constructing and executing basic text parsers. The pyparsing module is useful for evaluating user-definable expressions, processing custom application language commands, or extracting data from...
