solution s
A computer program consists of basic instructions such as:
|! |! |! |! |! |! |! |!
Input: A program gets data, perhaps from a file, keyboard, touchscreen,
|! |! |! |! |! |! |! |! |! |! |!
network, etc. |!
Process: A program performs computations on that data, such as adding two
|! |! |! |! |! |! |! |! |! |! |! |!
values like x + y. |! |! |! |!
Output: A program puts that data somewhere, such as to a file, screen, or
|! |! |! |! |! |! |! |! |! |! |! |! |! |!
network.
What is Python? |! |!
a high-level general-purpose programming language.
|! |! |! |!
Is Python an interpreted language?
|! |! |! |!
Yes, Python is an interpreted language. An interpreted language is a
|! |! |! |! |! |! |! |! |! |! |!
programming language that executes instructions directly by an interpreter. |! |! |! |! |! |! |! |!
When was Python originally released?
|! |! |! |!
1991
Python 1.0 was released in what year?
|! |! |! |! |! |!
, 1994
Why was it named Python? |! |! |! |!
The name Python came from Guido van Rossum (the creator) being a fan of
|! |! |! |! |! |! |! |! |! |! |! |! |! |!
the TV show Monty Python.
|! |! |! |!
The Python interpreter is
|! |! |!
a computer program that directly executes code written in the Python
|! |! |! |! |! |! |! |! |! |! |!
programming language. |!
Code is a common word for |! |! |! |! |!
the textual representation of a program (and hence programming is also
|! |! |! |! |! |! |! |! |! |! |!
called coding). |!
What is a statement? |! |! |!
A statement is a program instruction. A program mostly consists of a series of
|! |! |! |! |! |! |! |! |! |! |! |! |!
statements, and each statement usually appears on its own line.
|! |! |! |! |! |! |! |! |! |!
What is an expression? |! |! |!
Expressions are any code that return a value when it is evaluated by the |! |! |! |! |! |! |! |! |! |! |! |! |! |!
program; for example, the code "5 + 6" is an expression that computes a
|! |! |! |! |! |! |! |! |! |! |! |! |! |!
number by adding two values. |! |! |! |!
A new variable is created by
|! |! |! |! |!
performing an assignment statement using the = symbol, such as |! |! |! |! |! |! |! |! |! |!
favoritecolor = red |! |!
What character denotes comments in Python?
|! |! |! |! |!
The character '#' denotes comments
|! |! |! |!
For example: |!
# this is a comment
|! |! |! |!
