Intro To Python D335: Questions With Step-by-
Step Solutions
Nested Loop Correct Answer - A loop inside the body of
another loop.
f string Correct Answer - allows a programmer to create a
string with placeholder expressions that are evaluated as the
program executes
chr() Correct Answer - The chr() function returns the
character that represents the specified unicode. Syntax:
chr(number)
ord( ) Correct Answer - returns the number representing the
unicode code of a specified character. Syntax: ord(character)
Incremental Programming Correct Answer - starting with a
simple version of the program, and growing the program little by
little into a complete version
FIXME comment Correct Answer - attracts attention to code
that needs to be fixed in the future
// Correct Answer - floor division- rounds the result down to
the nearest whole number
break statement Correct Answer - A statement that causes a
loop to terminate early.
continue statement Correct Answer - A statement that causes a
loop to stop its current iteration and begin the next one.
, end=' ' Correct Answer - keeps the next print's output on the
same line separated by a single space
loop else Correct Answer - executes if the loop completes
normally
elif statement Correct Answer - An if statement which can
check for more than one condition. It is designed to stop after the
first match.
logical operators Correct Answer - The AND/OR/NOT
operators can be used to combine Boolean expressions (the
outcomes of relational operators or other logical operators).
function stub Correct Answer - a function definition whose
statements have not yet been written
pass keyword Correct Answer - performs no operation except
to act as a placeholder for a required statement
to return 1 Correct Answer - Good practice is for a stub to
return -1 for a function that will have a return value.
NotImplementedError Correct Answer - In some cases, a
programmer may want a program to stop executing if an unfinished
function is called. Ex: A program that requires user input should not
execute if the user-defined function that gets input is not completed.
raise NotImplementedError
Objects Scope Correct Answer - A variable or function object is
only visible to part of a program
Local Variable Correct Answer - A variable that can only be
accessed from a specific portion of a program
