D335: Introduction to Python (Sections 1-4) questions with
|\ |\ |\ |\ |\ |\ |\ |\
answers
1.Input: A program gets data, perhaps from a file, keyboard, touchscreen,
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
|\ network, etc. |\
2.Process: A program performs computations on that data, such as
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
adding two values like x + y
|\ |\ |\ |\ |\ |\
3.Output: A program puts that data somewhere, such as to a file,
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
screen, or network. |\ |\
4.computational thinking,: creating a sequence of instructions to solve a |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
problem
5.algorithm: A sequence of instructions that solves a problem
|\ |\ |\ |\ |\ |\ |\ |\
6.Python interpreter: a computer program that executes code written in
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the Python programming language.
|\ |\ |\
7.interactive interpreter: a program that allows the user to execute one line
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
|\ of code at a time
|\ |\ |\ |\
8.Code: a common word for the textual representation of a program
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
9.line: row of text
|\ |\ |\
1 |\/

,10.prompt: indicates the interpreter is ready to accept code
|\ |\ |\ |\ |\ |\ |\ |\
11.statement: a program instruction |\ |\ |\
12.Expressions: code that return a value when evaluated |\ |\ |\ |\ |\ |\ |\
13.cariables: named references to values stored by the interpreter
|\ |\ |\ |\ |\ |\ |\ |\
14.print(): function that displays variables or expression values
|\ |\ |\ |\ |\ |\ |\
15.'#": character tha denote comments, which are optional but can
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
be used to explains portions of code to a human reader
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
16.string literal: text enclosed in quotes (single or double) and can
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
contain letters, numbers, spaces, or symbols
|\ |\ |\ |\ |\
17.Why would a programmer add
|\ |\ |\ |\
end=' ' inside of print()?: To keep the output on the same line
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
18.print(variable_name) *without quotes*: to output the value of a variable |\ |\ |\ |\ |\ |\ |\ |\ |\
19.\n: newline character; output can be moved to the next line
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
20.whitespace: any space, tab, or newline |\ |\ |\ |\ |\
21.variable = input(): reads a user-enter string and changes it into a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
variable
22.type: determines how a value can behave
|\ |\ |\ |\ |\ |\
23.int(): converts a string to an integer
|\ |\ |\ |\ |\ |\
24.syntax error: violating a programming language's rules on how
|\ |\ |\ |\ |\ |\ |\ |\ |\
2 |\/
|\19
, symbols can be combined to create a program
|\ |\ |\ |\ |\ |\ |\
25.runtime error: program's syntax is correct, but the program attemps
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
an impos- sible operation, such as dividing by zero or multiplying
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
strings together |\
26.crash: Abrupt and unintended termination of a program
|\ |\ |\ |\ |\ |\ |\
27.SyntaxError: The program contains invalid code that cannot be
|\ |\ |\ |\ |\ |\ |\ |\ |\
understood.
28.IndentationError: The lines of the program are not properly indented.
|\ |\ |\ |\ |\ |\ |\ |\ |\
29.ValueError: An invalid value is used- can occur if giving letter to int().
