Intro Python- Printing in Python
Summary
TLDRThis video tutorial introduces viewers to the foundational concept of creating a basic Python program that displays text on the console. It explains how to use the 'print' statement, emphasizing the necessity of enclosing the text within parentheses and quotation marks to form a string. The video demonstrates the sequential execution of multiple 'print' statements, illustrating how the Python interpreter processes each line upon running the program. It encourages learners to practice using the 'print' statement in their own Python programs.
Takeaways
- 💻 The video teaches how to create a basic Python program that displays text on the screen.
- 📝 The text is displayed in a console window when the program is run.
- 🔑 The print statement is used in Python to display text, and it's enclosed within parentheses.
- 📑 Quotation marks are necessary around the text to be printed, and they can be either single or double.
- 🔡 A sequence of characters surrounded by quotes is referred to as a string in Python.
- 👀 The Python interpreter executes the program starting from the first line when the Run button is clicked.
- 🔄 If there are multiple print statements, they are executed in the order they appear in the code.
- 💡 A program is a sequence of instructions that the interpreter follows to perform actions.
- 📝 The video encourages viewers to practice using the print statement in their own Python programs.
Q & A
What is the purpose of the video?
-The purpose of the video is to teach viewers how to create a basic Python program that displays text on the screen.
What is the console window?
-The console window is where text appears when a Python program is executed, also known as the console.
How do you print text in Python?
-In Python, you print text using the print statement, which requires a set of parentheses and quotation marks around the text.
What is the significance of the word 'print' in Python?
-The word 'print' in Python is used to output text to the console and is the first part of the print statement.
Why are parentheses used in the print statement?
-Parentheses in the print statement are used to enclose the text or variables that are to be printed to the console.
What are quotation marks used for in the print statement?
-Quotation marks are used in the print statement to define the text string that should be printed to the console.
Can you use single quotes instead of double quotes in the print statement?
-Yes, you can use single quotes, but for consistency throughout the course, double quotes are used.
What is a string in Python?
-A string in Python is a sequence of characters surrounded by quotes, which can be either single or double.
How does the Python interpreter execute a program?
-The Python interpreter executes a program by jumping to the first line and executing it, then moving to the next line in order.
What happens when there are multiple print statements in a Python program?
-When there are multiple print statements, the Python interpreter executes them in the order they appear in the program.
What is the final instruction given to the viewers at the end of the video?
-The final instruction is to encourage viewers to try using the print statement in their own Python programs.
Outlines
💻 Introduction to Python Programming
This paragraph introduces the viewer to the basics of Python programming. It explains how to create a simple Python program that displays text on the screen, specifically in the console window. The paragraph demonstrates the use of the 'print' statement, which is fundamental in Python for outputting text. It details the syntax of the 'print' statement, emphasizing the need for parentheses and quotation marks to define the string that will be displayed. The paragraph also touches on the sequential execution of instructions in a Python program, showing how multiple 'print' statements are executed one after the other. Finally, it encourages the viewer to try using the 'print' statement in their own Python programs.

hi in this video you'll learn how to
make the most basic Python program one
which displays text on the screen when
you run these programs you'll see the
text appear on your screen in what is
called the console window or just the
console you can print in python using
the print statement it looks like this
first you have to start with the word
print this is pretty self-explanatory
you then need to include a set of
parentheses anything to be printed
should be included inside the
parentheses you need quotation marks
around the thing you want to print note
that you can use single or double quotes
but we'll be using double quotes
throughout this course the important
thing here is that the quotation marks
need to match a sequence of characters
surrounded by quotes is called a string
you'll learn more about strings later so
here we have your program or code on the
left and your console window on the
right when you click the Run button the
Python interpreter will jump right to
the first and in this case only line in
your program it executes that line and
you see hello world appear on your
console a program is essentially a
sequence of instructions if we have two
prints in our program instead of one
they will be executed in order the
interpreter executes s' the first one
and then it executes the second one now
it's your turn to try using the print
statement in your own Python programs
