.csv file
A .csv (Comma-Separated Values) file is a plain text file format for storing tabular data, where each line represents a row and uses commas to separate values in different columns.
.txt file
A .txt (Text) file is a common file format that contains plain text without specific formatting, making it suitable for storing and editing textual data.
Append
To “append” means to add or attach something to the end of an existing object, typically used in the context of adding data to a file or elements to a data structure like a list in Python.
Attribute
An “attribute” in Python refers to a property or characteristic associated with an object, which can be accessed using dot notation.
Broadcasting in NumPy
Broadcasting in NumPy allows arrays with different shapes to be combined in element-wise operations by automatically extending smaller arrays to match the shape of larger ones, making operations more flexible.
Component
In NumPy, a “component” typically refers to a specific element or value within a multi-dimensional array, which can be accessed using indexing.
Computation
Computation in NumPy involves performing numerical operations on arrays and matrices, making it a powerful library for mathematical and scientific computing in Python.
Data analysis
Data analysis is the process of inspecting, cleaning, transforming, and interpreting data to discover useful information, draw conclusions, and support decision-making.
DataFrames
A DataFrames in Pandas is a two-dimensional, tabular data structure for storing and analyzing data, consisting of rows and columns.
Dependencies
Dependencies in Pandas are external libraries or modules, such as NumPy, that Pandas rely on for fundamental data manipulation and analysis functionality.
File attribute
File attributes generally refer to properties or metadata associated with files, which are managed at the operating system level.
File object
A “file object” in Python represents an open file, allowing reading from or writing to the file.
Grid
In Python, a “grid” typically refers to a two-dimensional structure composed of rows and columns, often used to represent data in a tabular format or for organizing objects in a coordinate system.
Hadamard Product
The Hadamard product is a mathematical operation that involves element-wise multiplication of two matrices or arrays of the same shape, producing a new matrix with each element being the product of the corresponding elements in the input matrices.
Importing pandas
To import Pandas in Python, you use the statement: import pandas as pd, which allows you to access Pandas functions and data structures using the abbreviation “pd.”
Index
In Python, an “index” typically refers to a position or identifier used to access elements within a sequence or data structure, such as a list or string.
Libraries
Libraries in Python are collections of pre-written code modules that provide reusable functions and classes to simplify and enhance software development.
Linspace
In Python, “linspace” refers to a NumPy function that generates an array of evenly spaced values within a specified range.
NumPy
NumPy in Python is a fundamental library for numerical computing that provides support for large, multi-dimensional arrays and matrices, as well as a variety of high-level mathematical functions to operate on these arrays.
One dimensional NumPy
A one-dimensional NumPy array is a linear data structure that stores elements in a single sequence, often used for numerical computations and data manipulation.
Open function
In Python, the “open” function is used to access and manipulate files, allowing you to read from or write to a specified file.
Pandas
Pandas is a popular Python library for data manipulation and analysis, offering data structures and tools for working with structured data like tables and time series.
Pandas library
Pandas library in Python refer to the various modules and functions within the Pandas library, which provides powerful data structures and data analysis tools for working with structured data.
Plotting Mathematical Functions
Plotting mathematical functions in Python involves using libraries like Matplotlib to create graphical representations of mathematical equations, aiding visualization, and analysis.
