Integers are whole numbers without
decimal
points.
True
A string is a sequence of characters enclosed in
quotes
What is a character data type used for?
Single letters or symbols
What type of data is stored in a float data type?
Numbers with decimal points
Floats require more memory than integers.
True
A string is a sequence of characters enclosed in double
quotes
Match the numerical data type with its description:
Integer ↔️ Whole numbers without decimals
Float ↔️ Numbers with decimal points
A float data type stores numbers with decimal
points
What are strings used to store?
Sequences of characters
What type of numbers do integers represent?
Whole numbers
What type of values do characters store?
Single letters, numbers, symbols
What is the primary purpose of integers?
Storing whole numbers
Integers store numbers with decimal points.
False
Strings in Python have
variable
length.
What is the key difference between numerical and character data types in terms of operations?
Mathematical vs text manipulation
Implicit conversion is performed automatically by the compiler.
True
The `type()`
function
is used to check the data type of a variable.
True
A `TypeError` occurs when an operation is applied to an object of the wrong
type
.
What error occurs when trying to access an out-of-bounds index in a sequence?
IndexError
Data types
are categories that classify the kind of values a variable can
hold
Match the data type with its description:
Integer ↔️ Whole numbers without decimal points
Float ↔️ Numbers with decimal points
String ↔️ Text enclosed in quotes
Boolean ↔️ True or false values
Boolean values can only be either True or
False
.
True
An integer is a whole number without
decimals
An integer is a whole number without decimal
points
What type of quotes are used to enclose characters in Python?
Single quotes
Strings can be manipulated using operations like
concatenation
.
True
What type of data is represented by a character data type?
Single text symbols
Integers cannot store values with
decimal
points.
True
Floats are used to store numbers with
decimal
Strings are enclosed in
double quotes
.
True
Floats can store numbers with
decimal
points.
How are floats represented when they are very small?
Scientific notation
Numerical data types are used to represent text.
False
Numerical data types represent numbers, while character data types represent text or
symbols
.
What method is used for explicit data type conversion?
Type conversion functions
Understanding data type conversion is crucial for
compatibility
between different data types.
What is the output of `print(type(10))` in Python?
<class 'int'>
A `ValueError` occurs when a function receives an
argument
with the correct type but an invalid value.
True
