A sequence of characters enclosed in single or double quotes. It can represent text, words, and sentences.

A data type in Python that represents whole numbers without any decimal places.

A data type in Python that represents numbers with decimal points.

A data type that represents either True or False.

A value that never changes throughout the program's execution.

A named storage location that holds a value which can be changed during program execution.

A sequence of instructions that tells a computer how to perform a specific task.

Translating a program written in a programming language into machine-readable code (object code or machine code).

Errors detected during program execution, caused by instructions the computer cannot understand or execute.

Errors that occur when the program logic is incorrect, resulting in unexpected or incorrect results.

A set of steps or rules used to solve a problem or complete a task.

The process of writing the instructions for a program in a specific programming language.

Steps involved in creating a computer program, from understanding requirements to testing and deployment.

A method used to calculate the factorial of a number, involving repeated multiplication of consecutive integers.

A program is akin to a recipe. Variables are like ingredients, and statements are like instructions telling the computer how to manipulate those variables.

A high-level programming language is more human-readable and easier to understand compared to low-level languages.

Low-level languages, like assembly language, are closer to the computer's native language and harder for humans to understand.

A compiler, interpreter, or assembler translates code written in a programming language into machine language - the computer's native language.

A statement is an instruction written in a high-level programming language. It directs the computer to perform a specific action.

An expression in programming represents a value. It combines symbols according to the language's rules.

Operands are values, and operators are symbols that define actions. An expression must have at least one operand and one operator.

Expressions are used in various applications like programming, database systems, and spreadsheets. For example, in databases, they are used in queries to retrieve specific data.

The process of assigning a value to a variable using an equal sign ('='). It connects a variable name to a specific value.

In Python, you can create a variable by assigning a value directly without declaring its data type. The interpreter automatically determines the data type based on the value.

In some languages (like C/C++), you need to declare the data type of a variable explicitly before using it. This tells the compiler what kind of data the variable can hold.

The operation that calculates the remainder after dividing two numbers. For example, 14 % 4 equals 2 (because 14 divided by 4 leaves a remainder of 2).

A type of division where the result is always an integer (whole number), discarding any decimal part. In Python, '//' represents integer division (e.g., 14 // 4 equals 3).

A control structure that executes statements in the order they are written, following a linear path.

A process that allows the program to choose between different paths of execution based on conditions or parameters.

A control structure that uses selection logic, allowing the program to make choices based on conditions.

A statement that transfers the control of the program to a different part of the code, altering the default sequential flow.

A programming construct that allows a section of code to be executed repeatedly, as long as a certain condition is met.

A type of iteration where the code block is executed a specific number of times. It is often used to perform repetitive tasks for a fixed count.

A type of iteration where the code block is executed repeatedly until a specific condition is met, checking the condition after each iteration. It is often used for tasks requiring the execution to continue until a specific criterion is achieved.

A special statement used to immediately exit the current loop iteration, skipping the remaining code within the loop for that particular iteration, but continuing with the next iteration if there is one.

A programming structure that allows a program to choose between different actions based on a condition. It executes a specific block of code if the condition is true, and optionally executes another block if the condition is false.

A type of conditional statement that allows a program to execute one block of code when a condition is true, and does nothing if the condition is false. It consists of the 'if' keyword followed by the condition and the code block to be executed if the condition is true.

A type of conditional statement that allows a program to choose between two different blocks of code based on a condition. It consists of the 'if' keyword followed by the condition and the code block to be executed if the condition is true, and the 'else' keyword followed by the code block to be executed if the condition is false.

A type of conditional statement that allows a program to choose between multiple blocks of code based on multiple conditions. It consists of the 'if' keyword followed by the first condition, the code block executed if the first condition is true, and then subsequent 'else if' statements with their respective conditions and code blocks. It may also include a final 'else' statement with its code block to be executed if none of the previous conditions are true.

Keywords used in Python to define conditional structures: 'if', 'elif' (short for 'else if'), and 'else'.

The if statement, if...else statement, and switch statement (or if-else if in Python).

The process of evaluating the truth or falsity of a condition in a conditional statement. It determines which block of code to execute based on the result of the evaluation.

The block of code that is executed if the corresponding condition in a conditional statement is true. The code may contain any valid Python instructions, including variable assignments, function calls, and other conditional statements.
