The Python json.decoder.JSONDecoder.parse_constant attribute is used to specify a custom function for handling special constant values in JSON, such as Infinity, -Infinity, and NaN.By default, Python converts t

In python, the PySpark module provides processing similar to using the data frame. A lit function is used to create the new column by adding constant values to the column in a data frame of PySpark. It helps interfacing RDDs, which is achieved using a library of py4j. Pyspark is nothing...
This plugin folds enumerated constants to their names upper case constants to their values for better readability in Python.
