What is a program?

What is an Instructions List?

a predetermined set of known commands

what are the 4 components of a language?

Alphabet, Lexis, Syntax, and Semantics?

What is the “alphabet” component supposed to mean?

symbols to build words

What is the “lexis” component supposed to mean?

set of words the language offers

What is the “syntax” component supposed to mean?

set of rules determining the validity of a sentence

What is the “semantics” component supposed to mean?

what is a high level programming language?

language that can be understood by both humans and computers

What is “source code”?

program written in high programming language

what is “source file”?

file containing the source code

what is “low level programming language”?

language that directly instructs the computer; often used for designing computer systems

what is “compilation”?

Uses a compiler or a translator
The source program is translated once by getting a file containing the machine code.

Each modification must be translated and processed.

Can be distributed worldwide

what is “interpretation”?

Uses an interpreter

“read-check-execute” process

Translates the source program each time it has to be run

Program built using interpreters need its end user to have an interpreter to use it

Slower than compilation

what is a “bytecode”?

a low-level set of instructions that is portable across different platforms

what is “parsing”?

A technique used to analyze and interpret the syntax of a text or program to extract relevant information.

what are “scripts”?

source programs encoded using scripting language

What is “Python”?

a scripting language that is designed to be utilized in the interpretation manner

Requires a Python interpreter

what is the standard Python application that comes with its installation?

Integrated

Development &

Learning

Environment

what is the common Python file extension?

_.py

what are functions?

actions the language already knows how to perform. It causes some effects or evaluates the value and return it as a function’s result.

what are arguments?

value that are sent to the function when it is called

different types of arguments

positional arguments

keyword arguments

what are positional arguments?

values passed into a function during a function call that are assigned to parameters based solely on their position or order in the argument list. The order of the arguments must match the order of the parameters defined in the function signature.

what are keyword arguments?

consists of a keyword identifying the argument, an equal sign, and a value

what are parameters?
