A Data frame is a two-dimensional data structure, i.e., data is aligned in a tabular fashion in rows and columns. And it is stored at a location – C:\Users\Owner\Documents\json.json, Converting this json file into a csv file is a single line of code –, Series is a one-dimensional labelled ndarray. Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric Python packages. import os import pandas Domain = ["IT", "DATA_SCIENCE", "NETWORKING"] domain_dict = {'Domain': Domain} data_frame = pandas.DataFrame(domain_dict) So, we use pandas.DataFrame() function to create a data frame out of the passed data values in the form of Dictionary as seen above. Understanding file extensions and file types – what do the letters CSV actually mean? Pandas Cleaning Data Cleaning Empty Cells Cleaning Wrong Format Cleaning Wrong Data Removing Duplicates.
