Python – Questions With Comprehensive
Solutions
Python interpreter Correct Answer - a computer program that
executes code written in the Python programming language
Prompt Correct Answer - >>> inticates the interpreter is ready
to accept code
Statement Correct Answer - program instruction
A program mostly consists of a series of statements, and each
statement usually appears on its own line
Comment character Correct Answer - #
Outputting multiple items with one statement Correct Answer -
use a comma to seperate
ex) print('wage: ', wage)
Newline characters Correct Answer - \n
ex) ('1\n2\n3') prints
1
2
3
Print() can also be used to create a newline
What is the purpose of end=' ' Correct Answer - by default in
python each print statement starts a new line, end=' ' indicates that
it should instead put the next print on the same line following a
space
,Input function Correct Answer - input()
Gets input from the user
Converting user input to integer Correct Answer - using int()
ex)
my_string = '123'
my_int = int('123')
Input prompt Correct Answer - Adding a string inside the
parentheses of input() displays a prompt to the user before waiting
for input
ex)
hourly_wage = int(input('Enter hourly wage: '))
will display Enter hourly wage: and wait for input
Default input will be string and only requires input()
Syntax errors Correct Answer - to violate a programming
language's rules on how symbols can be combined to create a
program. An example is putting multiple prints on the same line.
Runtime errors Correct Answer - 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').
IDEs Correct Answer - integrated development environment
embeds a python interpreter so that the reader may experiment
with python programming
IDLE is the official python IDE
How to type a backslash (\) Correct Answer - \\
, One backslash thinks you are going to start a newline
Python 3 reserved words Correct Answer -
Value Correct Answer - a value such as 20, abcdef, or 55
Type Correct Answer - the type of object such as a string or
integer
Identity Correct Answer - identifier that describes the object
Mutability Correct Answer - indicates if the objects value is
allowed to change
Integers and strings are immutable; modifying their values with
assignment statements results in new objects being created and the
names bound to the new object
Must change entire string to change character
ex) alphaber[1] = 'C' is not allowed
Print an objects type Correct Answer - print(type(x))
Print an objects identity Correct Answer - print(id(x))
Prints a large number that is the unique location in memory where
the object is stored
Floating point literal Correct Answer - a fraction of a float
ex) 1.1 or 1.0 or 1.212
Overflow error Correct Answer - Error from attempting to
represent a number that is too large.
