· A set of languages available in the computer
· A process for getting duplicate values removed from a list
· A list of instructions that the computer has to follow to reach a goal
· A file that gets copied to all machines in the network
Explanation: A computer program may be thought of as a collection of instructions that a computer follows in order to complete a task. It's a string of instructions written in code that tells the computer how to carry out a certain activity or set of operations. Imagine it as a recipe that you provide to your computer, informing it how to process and change data in order to get the result that you want.
2. What’s the syntax of a language?
Answers
· The rules of how to express things in that language
· The subject of a sentence
· The difference between one language and another
· The meaning of the words
Explanation: The term "syntax" is used to refer to the rules that are used in programming languages to determine how programs should be constructed. The syntax of a programming language may be compared to this. The syntax is what specifies the appropriate order of symbols, keywords, and other components that go into the construction of a good program.
3. What’s the difference between a program and a script?
Answers
· There’s not much difference, but scripts are usually simpler and shorter.
· Scripts are only written in Python.
· Scripts can only be used for simple tasks.
· Programs are written by software engineers; scripts are written by system administrators.
Explanation: There is a difference that should be made, despite the fact that the words "program" and "script" are often used interchangeably with one another.
A collection of instructions or code that is developed to do a particular job on a computer is referred to as a program. It is a more general phrase that refers to a wide variety of software, such as applications, system software, and utilities. It covers all of these categories. Before being run, programs are often converted into machine code or an intermediate code. Compilation occurs before execution.
On the other hand, a script is a kind of computer program that is interpreted rather than compiled. Scripts are often used in web-based applications. Scripts are often created in scripting languages such as Ruby, Python, or JavaScript. They are often used for the purposes of automating processes, carrying out duties related to system management, or extending functionality to other applications. Scripts are often understandable by humans and may be modified on the fly, eliminating the need for a separate process to compile the changes.
To reduce it all the way down to its most fundamental level, every program is a script, but not every script is a program. The difference is in the manner in which they are carried out, namely, either via compilation or interpretation.

11. What are functions in Python?
Answers
· Functions let us use Python as a calculator.
· Functions are pieces of code that perform a unit of work.
· unctions are only used to print messages to the screen.
· Functions are how we tell if our program is functioning or not.
Explanation: In Python, a function is a section of code that may be reused and is designed to carry out a certain operation. The def keyword comes first, then the function name, then the arguments encased in parentheses, and finally a colon. This is how functions are defined. The code that will be run whenever the function is invoked may be found in the indented "body" of the function, which is formatted using tabs.
12. What are keywords in Python?
Answers
· Keywords are reserved words that are used to construct instructions.
· Keywords are used to calculate mathematical operations.
· Keywords are used to print messages like “Hello World!” to the screen.
· Keywords are the words that we need to memorize to program in Python.
Explanation: Because they are considered to be part of the syntax of the language, keywords in Python are words that cannot be used as identifiers (variable names, function names, etc.) even if they have specific meanings associated with them. The Python programming language's syntax and semantics are both specified by these terms.

Answers
· A file that gets printed by the Python interpreter.
· The syntax and semantics of a programming language.
· The overview of what the computer will have to do to solve an automation problem.
· Step-by-step instructions on how to complete a set of tasks, to be executed by a computer.
Typically, the goal of developing a computer program is to provide a solution to a certain issue or to automate a particular procedure. It is made up of directives, or statements, as well as functions and algorithms, which lay out the steps that need to be carried out by the computer. The term "program" may refer to anything from a short script that executes a single command to a complex piece of software that consists of a number of interconnected modules.
A computer program's primary function is to mediate communication between the human user and the computer hardware, therefore empowering the latter to carry out the actions specified by the former (the programmer).
