D335 Python Study-Questions and Answers Verified
100% Correct
python interpreter
program that executes code written in python
interactive interpreter
program that allows the user to execute one line of code at a time
line
row of text
prompt
(">>>") indicates the interpreter is ready to accept code
statement
program instruction
expressions
code that return a value when evaluated
variables
named references to values stores by the interpreter
end=' '
A keyword parameter for the print() function that causes the function to NOT add a newline at
the end of the string.
runtime error
wherein a program's syntax is correct but the program attempts an impossible operation, such
as dividing by zero or multiplying strings together (like 'Hello' * 'ABC').
,logic error
An error in a program that makes it do something other than what the programmer intended.
aka a bug
IDLE
official python IDE
basic environment for editing and running programs
PEP 8
The official guidelines for Python code formatting
garbage collection
automated process of deleting unused objects, helps keep memory of the computer less
utilized
name binding
process of associating names with interpreter objects
mutability
indicated whether the objects value is allowed to be changed
immutable
unchangeable, integers and strings are immutable
floating-point number
a real number, like 98.6, 0.0001, or -666.667. The term "floating-point" refers to the decimal
point being able to appear anywhere ("float") in the number. Thus, float is a data type for
floating-point numbers.
floating-point literal
written with the fractional part even if that fraction is 0, as in 1.0, 0.0, or 99.0.
, scientific notation in python
written using an e preceding the power-of-10 exponent, as in 6.02e23 to represent 6.02x1023.
The e stands for exponent. Likewise, 0.001 is 1x10-3, so it can be written as 1.0e-3.
overflow
error that results when the number of bits is not enough to hold the number
symbol for outputting certain number of digits after decimal point
:2f}' (for 2 digits after decimal point)
expression
combination of items, like variables, literals, operators, and parentheses, that evaluates to a
value, like 2 * (x + 1)
literal
specific value in code like 2
operator
symbol that performs a build-in calculation like + which does addition
**
exponent operator
floor division operator
Rounds the quotient down to a whole number after division
module
Python code located in another file. The programmer can import the module for use in their
own file, or in an interactive interpreter. The programmer first imports the module to the top of
a file.
