Creating a virtual environment (Optional)

Note that by creating virtual environment you need to install all the required modules again. Also everything you do in the terminal must be done after activating the virtual environment

Run the following command in terminal

python -m venv name_of_environment
# Example:
python -m venv virt

Activating a virtual environment

# In git bash
source name_of_environment/Scripts/activate
# In this example:
source virt/Scripts/activate

# In cmd
name_of_environment\Scripts\activate
# In this example:
virt\Scripts\activate

Deactivating a virtual environment

just run the command: deactivate

Installation of flask

pip install flask

Starting with coding and Starter code

Firstly let us create a file named app.py in the current directory. And then write/paste the below code in it.

from flask import Flask

app = Flask(__name__)

@app.route('/')
def home():
    return 'myCODEnotein is best'

if __name__=="__main__":
    app.run(debug=True) # True only while development
