Getting started Python using Visual Studio Code

Check Python is already installed or not

• To check if you have python installed on a Windows PC. Go to the Terminal and type python --version
• If Python is installed, you will see the version of Python installed.
• Otherwise, install python using the following steps.

Installing Python

• Download and install Python from the official website: https://www.python.org/downloads/
• Check python version using the following command in the terminal.

  python --version
  

Sample Output:
Python 3.12.0

• Install the Python extension for Visual Studio Code: https://marketplace.visual studio.com/items?itemName=ms-python.python

Setting up the project

• Open Visual Studio Code
• Click on the “File” menu and select “New File”
• Save the file with the extension “.py”. For example - fibonacc.py
• Write your Python code in the file. Here I write the following code.

# The function fib(n) is defined. This function generates the Fibonacci sequence up to the nth term.
# The function takes an integer n as input and prints the first n Fibonacci numbers separated by spaces.

def fib(n):
    a = 0
    b = 1
    if n == 1:
        print(a)
    else:
        print(a)
        print(b)

        # Run a loop from 2 to n
        for i in range(2,n):
            c = a+b
            a = b
            b = c
            print(c)

n = int(input("Enter the number of fibonacci numbers you want to print "))
fib(n)

• Save the file
• Open the command palette (Ctrl+Shift+P)
• Type “Python: Create Terminal”
• Click on the terminal that opens
• Type python fibonacci.py in the terminal. You will see the ouput.

Or.

• Run the application using Run button on upper right corner of Visual Studio Code.

Or.

• Set a debug point and click Debug python file using upper right corner of Visual Studio Code.
