AI (artificial intelligence) is the ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings.

Application development, or app development, is the process of planning, designing, creating, testing, and deploying a software application to perform various business operations.

Arithmetic operations are the basic calculations we make in everyday life like addition, subtraction, multiplication and division. It is also called as algebraic operations or mathematical operations.

Set of numbers or objects that follow a pattern presented as an arrangement of rows and columns to explain multiplication.

Assignment operator is a type of Binary operator that helps in modifying the variable to its left with the use of its value to the right. The symbol used for assignment operator is “=”.

Symbol “* “ used to perform various operations in Python.

A backslash is an escape character used in Python strings to indicate that the character immediately following it should be treated in a special way, such as being treated as escaped character or raw string.

Denoting a system of algebraic notation used to represent logical propositions by means of the binary digits 0 (false) and 1 (true).

A colon is used to represent an indented block. It is also used to fetch data and index ranges or arrays.

Link (things) together in a chain or series.

Data engineers are responsible for turning raw data into information that an organization can understand and use. Their work involves blending, testing, and optimizing data from numerous sources.

Data Science is an interdisciplinary field that focuses on extracting knowledge from data sets which are typically huge in amount. The field encompasses analysis, preparing data for analysis, and presenting findings to inform high-level decisions in an organization.

Data type refers to the type of value a variable has and what type of mathematical, relational or logical operations can be applied without causing an error.

Symbol “ “ used to represent strings in Python.

An escape sequence is two or more characters that often begin with an escape character that tell the computer to perform a function or command.

An expression is a combination of operators and operands that is interpreted to produce some other value.

Python float () function is used to return a floating-point number from a number or a string representation of a numeric value.

Symbol “/“ used to perform various operations in Python

Denoting an underlying basis or principle; fundamental.

Immutable Objects are of in-built datatypes like int, float, bool, string, Unicode, and tuple. In simple words, an immutable object can’t be changed after it is created.

An integer is the number zero (0), a positive natural number (1, 2, 3, and so on) or a negative integer with a minus sign (−1, −2, −3, and so on.)

Is the process of modifying a string or creating a new string by making changes to existing strings.

A mathematical convention is a fact, name, notation, or usage which is generally agreed upon by mathematicians.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
