Using Python: Part 1: Console Input and Output
Summary
TLDRThis Python tutorial focuses on console input and output, essential for interacting with the command line interface. It introduces the 'input' function to capture user text and the 'print' function to display text back to the console. The video demonstrates how to use these functions to receive and show information, highlighting their importance in console-based Python programming.
Takeaways
- 💻 The video is about using Python for console input and output.
- 🔑 The console is a non-graphical user interface, also known as the command line.
- 📝 The 'input' function in Python is used to take textual input from the console.
- 📢 The 'print' function in Python is used to display text on the console.
- 🔍 The input function captures whatever is typed on the console and returns it.
- 📌 The print function takes an argument and displays it on the console.
- 💬 The video demonstrates how to use 'input' and 'print' functions in a Python script.
- 🎥 The presenter runs a Python script to show how input is echoed back using the 'input' function.
- 🔧 Both 'input' and 'print' are essential for working with the console in Python.
- 📚 The video concludes by emphasizing the importance of input and output in console-based Python programming.
Q & A
What is the primary purpose of using Python's console input and output?
-The primary purpose is to interact with users by taking input from the console and displaying output back to it, facilitating communication between the user and the Python program.
What is the function used in Python to get input from the console?
-The function used in Python to get input from the console is `input()`.
How does the `input()` function work in Python?
-The `input()` function in Python takes the text entered by the user on the console and returns it as a string, which can then be stored in a variable.
What is the function used in Python to display output on the console?
-The function used in Python to display output on the console is `print()`.
How does the `print()` function display information on the console?
-The `print()` function takes the arguments provided to it and displays them on the console as output, which can be text or values of variables.
What happens when you run a Python script that uses the `input()` function?
-When you run a Python script with the `input()` function, the program execution pauses, waiting for the user to enter text and press Enter before proceeding.
Can the `input()` function be used to get non-textual input from the console?
-No, the `input()` function is designed to receive textual input. If numerical input is needed, it must be converted from the string returned by `input()`.
What is the significance of the line number mentioned in the script when discussing the `input()` function?
-The line number mentioned in the script refers to the specific location in the code where the `input()` function is used to demonstrate how to capture user input.
Can the `print()` function be used to display multiple pieces of information on the console?
-Yes, the `print()` function can be used to display multiple pieces of information by passing multiple arguments separated by commas.
What is the practical application of using `input()` and `print()` functions in Python?
-The practical application includes creating interactive programs, taking user commands, processing data based on user input, and providing feedback or results to the user.
How can you ensure that the user input is of the expected type when using the `input()` function?
-To ensure the user input is of the expected type, you can use type conversion functions like `int()`, `float()`, or `str()` to convert the input string to the desired data type.
Outlines
💻 Introduction to Python Console I/O
This paragraph introduces the topic of console input and output in Python. The speaker explains the need for taking textual input from the console, which is the non-graphical user interface or command line, and displaying text back to it. Two primary functions are highlighted for this purpose: the 'input()' function to receive input from the user and the 'print()' function to display information on the console. The script demonstrates how these functions work by showing a simple example where the user's input is captured and then echoed back using the 'print()' function. The paragraph concludes with a brief acknowledgment of the utility of these functions in working with the console in Python.

Thanks for watching and conclusion of the tutorial
Transcripts
welcome to the toy video on using Python
in this video I'm going to talk about
console input and output when working
with Python sometimes we want the
ability to take input from the console
that is the non graphical user interface
sometimes called the command line we
want to be able to get input usually
textual from that as well as do
something with it and also display text
back to it so working with the console
and using input and output there's two
different primary functions we can use
in Python to do that the first to get
input is the helpfully named input
function and you see that right here on
line 3 we see we're using the input
function whatever is typed on the
console will be returned and placed
within this variable so it's a result
will be returned and we're signing it to
the value of this variable secondly to
display something to print something
python has the helpfully named print
function and in fact we're using it in
the previous learning Python series to
show different information on the
console so we use the print function to
print some value to put it on the
console so we can see it and we see that
here at line 6 the print function here
and whatever is supplied to it send as
an argument a parameter to this function
will be then shown on the console so
let's run this I've clicked run if I
type some words and press Enter
wouldn't see that echoed back to us so
we use the input function and python to
get input from the console and we can
use the print function to then display
those values on the console as well
using input and print as part of the
input and output part of working with
the console in Python thanks for
