One pathway may be from the web (i.e., from an API or a GitHub repository) import pandas as pd The only major argument that it requires is a pathway that outlines where the file exists. Fortunately, in the Pandas library, it has a function that works to convert the data in this format into a DataFrame called pandas.read_csv(). We can find these datasets in multiple types of files, but we most commonly find them in the form of comma separated value files (CSVs). In the real world, a dataset is often read into Python via an external source that curated it.

When it comes to creating a DataFrame, you can either import it from an external file or create it yourself in Python. The principal library used in working with these structures is Pandas. Index - a unique identifier for each data entryĪlthough these can have different names depending on the programming language or application tool being used, in Python, we call these structures DataFrames.Columns - corresponding to a grouping relating to a singular quality of each given data point that are usually titled.Rows - representing a singular data entry point.These structures have several unique qualities: Aggregates of each of these rows, that represent a given data entry, and their properties are formed into a two-dimensional structure where titled columns consist of values of the same property. You are likely already familiar with this if you’ve ever worked with an Excel spreadsheet or a SQL table. For the majority of cases, most data are in tabular form (i.e., data structured into rows representing a single entry). To start, it’s important to know that there are a variety of different structures that data can take. However, what’s often under-appreciated-but-highly-valuable about Python is the ease with which we can manipulate data with flexible data structures. Qualities like its scalability and variety of libraries for data analysis and data science applications make it versatile. Python is a powerful tool when it comes to working with data. This article will look at some of the ins and outs when it comes to working with DataFrames. When it comes to exploring data with Python, DataFrames make analyzing and manipulating data for analysis easy.
