Oceanography Install Python There are Python Editors, called as IDE (Integrated Python Versions Development Environment). The major Python IDEs for Execute Python programs Python are Thonny, Pycharm, Netbeans, Spyder and Eclipse. Running the first My preference is Thonny. program Comments in Python Summary Introduction to Python Versions Python What is Python History of Python Python as two major versions Features of Python Applications of 1. Version - 2 Python Python and 2. Version - 3 Oceanography Install Python In Linux, python version 2 is called simply as 'python' but Python Versions Execute Python python version 3 is called as python3. Check the version programs number by executing the commands 'python {version' and Running the first 'python3 {version' in a linux terminal. program Comments in Python It is better to work with the version - 3. So make sure that Summary python3 is installed. Introduction to Execute Python programs Python Method-1: Using Python commandline (in Linux) What is Python Open terminal, type "python3". This will open the python History of Python Features of Python command-line where python commands can be executed one Applications of by one. Python Python and Oceanography Install Python Python Versions Execute Python programs Running the first program Comments in Python Summary Introduction to Python Method-2 : Python IDE What is Python Open the installed python IDE and write the code in the text History of Python editor. Save with file extension as ".py". Run the code. Features of Python Applications of Python Python and Oceanography Install Python Python Versions Execute Python programs Running the first program Comments in Python Summary Method - 3: Outside Python environment Introduction to Python Type python code in a normal text editor. Save file with ".py" as file extension. In a linux terminal and type the What is Python command "python3 file.py" where file.py is the python file. History of Python Features of Python Applications of Python Python and Oceanography Install Python Python Versions Execute Python programs Running the first program Comments in Python Summary Introduction to Running the first program Python What is Python Problem : Write a python program to print "Hello World !" History of Python Features of Python Applications of Code Python Python and Oceanography print("Hello World !") Install Python Python Versions Execute Python (Note that 'print' command is used to display output to programs screen) Running the first program Do the program in all the three ways: Comments in Python 1. In python command-line Summary 2. In Python IDE 3. Outside Python Environment Introduction to Comments in Python Python What is Python History of Python I Comments are plain text written into the program to Features of Python Applications of explain the code. Python I Comments can be used to make the code more readable. Python and Oceanography I Comments can be used to prevent execution of certain Install Python code while testing. Python Versions Execute Python Example programs Running the first program Comments in # This program prints "Hello World" Python print("Hello World !") Summary Introduction to Python Example What is Python History of Python print("Hello World !") # This line ... Features of Python Applications of Python Python and Example (Multi-line comments) Oceanography Install Python Python Versions """ This program prints "Hello World" Execute Python programs This was created on 17-02-2018 Running the first Modified on 12-11-2018 program """ Comments in Python print("Hello World !") Summary Introduction to Summary Python What is Python History of Python Features of Python I Python is one of the most used computer programming Applications of language. Python Python and I Python is used in Oceanography along with Fortran Oceanography Install Python I Python can also be used for data visualization Python Versions (graphics) Execute Python I Use Python IDE for doing programs programs Running the first I In python, 'print' command is used to print outputs. program Comments in I Comments starts with '#' character. Include comments Python in your program.
