1.1.3 Input and output

• What is input in programming?

  Data received by the program
• What is the primary way to take input from a user in Python?

  `input()` function
• The `input()` function returns data as a string
• Variables are used to store input data and results before displaying them.
• What is the purpose of data type conversion in Python?

  Ensures data is in correct format
• Match the input/output function with its purpose and data type:

  `input()` ↔️ Takes user input, returns a string

  `print()` ↔️ Displays output, data type can be any
• What are input streams in programming?

  Channels through which data enters
• Keyboard input allows users to enter data directly via the keyboard
• File input reads data from files stored on a system.
• Arrange the common types of input streams by their data source:

  1️⃣ Keyboard Input: Keyboard

  2️⃣ File Input: Files

  3️⃣ Network Input: Networks
• What is the syntax for using the `input()` function in Python?

  $variable =$$input("Prompt")$
• The `input()` function always returns data as a string
• Data type conversion ensures that data matches the program's requirements.
• What is the purpose of an input function in programming?

  Receives data from users
• What is the purpose of the `input()` function in Python?

  Takes user input
• The `print()` function in Python can display data of any type
• Python uses `input()` for input and `print()` for output.
• What data type does the `input()` function return in Python?

  String
• The `print()` function in Python can display data of any type
• The `input()` function in Python always returns data as a string.
• What is the purpose of the `print()` function in Python?

  Displays output
• The `input()` function in Python returns data as a string
• What data type can the `print()` function display in Python?

  Any
• The `print()` function in Python can output data to the console.
• The `input()` function in Python returns data as a string
• What is the primary use of the `print()` function in Python?

  Displays output
• The `input()` function in Python receives data from external sources.
• Which data type does the `input()` function return in Python?

  String
• An input stream is a channel that data enters a program from external sources
• What are the three common types of input streams in Python?

  Keyboard, file, network
• Match the input stream with its data source and use case:

  Keyboard Input ↔️ Keyboard, user interaction

  File Input ↔️ Files, reading configurations

  Network Input ↔️ Networks, real-time data updates
• Variables and data types are essential for handling data received through input streams.
• What is the primary purpose of input functions in programming?

  Receive data
• The `input()` function in Python returns data as a string
• Data type conversion is necessary when the input data is not in the required format.
• What calculation is performed in the example code to calculate the area of a rectangle?

  Length * Width
• An input function receives data from users or external sources
• The `input()` function in Python always returns data as a string.
• What operation is performed in the example code to calculate the area of a rectangle?

  Multiplication
• An output stream is a channel through which a program sends data to an external destination
