    • 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
