  • 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
