Real cs 5-9 true false

The break statement can be used to exit a loop prematurely

True

It is possible to use the break statement to exit multiple nested loops at once

False

The continue statement skips the rest of the current iteration and moves to the next

True

The sequence from range(n) starts at 1 and goes up to (but not including) n

False

Nested loops require using both for and while loops

False

Infinite loops occur when the loop condition never becomes false or there is no exit statement in the body

True

The body of a while loop is guaranteed to execute at least once

False

A while True loop runs indefinitely until a break or an error occurs

True

The loop condition in a while loop is evaluated before each iteration

True

The loop control variable in for x in range(2) can be accessed outside the loop

True

A function must always have a return statement

False

A variable defined within a function is limited to that function and not accessible outside it

True

You can call a function without passing arguments even if it has parameters with no default value

False

If a function lacks a return statement (or returns without a value) it implicitly returns 0

False

A function can have multiple parameters with the same name as long as they have different default values

False

Keyword arguments are passed by position and positional arguments are specified by name

False

Passing a mutable object to a function allows the function to modify that object

True

break and return are interchangeable

False

A function may have multiple return statements but only one executes per call

True

Functions can return multiple values with a comma-separated return (tuple packing)

True

Python allows creating a class with no attributes or methods

True

Variables defined in init need the self prefix to become instance attributes

True

All user-defined classes in Python are mutable

False

If a class lacks str — you can still print an object of that class

True

You can instantiate a user-defined class without explicitly defining init

True

All attributes of a class can be accessed and modified from outside the class

False

Modifying an attribute of one instance affects that attribute in all other instances

False

When creating a class object you must explicitly provide values for all instance attributes

False

In method definitions — self refers to the instance and lets the method access its attributes

True

You can change an object’s class after it is created

False

If init defines attributes — all instances of the class will have those attributes

True

Characters are a different type from strings in Python

False

If s1 == s2 then s1 in s2 returns False because in checks partial matches

False

You can directly modify a character in a string with s[2] = 'z'

False

To loop over indices of s you can use for i in range(len(s) + 1)

False

Strings are 0-based indexed

True

strip() removes both leading and trailing whitespace

True

Relational operators compare strings by length

False

Strings can be indexed using negative numbers

True

For a string s — min(s) == max(s) is always False

False

islower() · isdigit() · isalpha() are standalone functions (not methods)

False

In for i in s — i refers to a character of s each iteration

True

Comparing two lists of different lengths causes an error

False

It is possible to directly convert a list to a string in Python

True

append() adds an element to the beginning of a list

False

[x for x in range(10) if not x % 2] creates a list of only positive even integers

False

Lists cannot be negatively indexed

False

remove() deletes an element by index

False

You can convert items of other (iterable) types directly to a list

True

Lists can only contain items of the same data type

False

The += operator can concatenate two lists

True

Lists have a fixed maximum size after which you cannot add elements

False

pop() removes and returns the last element of a list (by default)

True
