​​Papermill

Papermill is a tool for parameterizing, executing, and analyzing Jupyter Notebooks.

Papermill lets you:
* parameterize notebooks
* execute notebooks

This opens up new opportunities for how notebooks can be used. For example:
* Perhaps you have a financial report that you wish to run with different values on the first or last day of a month or at the beginning or end of the year, using parameters makes this task easier.
* Do you want to run a notebook and depending on its results, choose a particular notebook to run next? You can now programmatically execute a workflow without having to copy and paste from notebook to notebook manually.

- Create an app instance.
- A path operation decorator (like @app.get("/")).
- A path operation function - async def root()
- And finally Run the development server uvicorn from command line.

Practice Code: 051

Write a program to return the sum of a series of sequential numbers. The sequence can be
a. 1,2,3,4,5.......n
b. 1,3,5,7,9,11,.....n
c. 2,4,6,8,10,12.....n
d. 35,42,49,56,63....n

Note: Do not use a loop to add the numbers, if that is what your idea is, not use a sum() or similar function to add them.

Write an algorithm that optimally finds the sum total.

Connecting to Amazon Redshift database and Inserting data

import psycopg2
con=psycopg2.connect(dbname= 'dbname', host='host', port= 'port', user= 'user', password= 'pwd')

#once the above code executes and connection is established
# create a cursor
cur = con.cursor()

#now you can execute select statements
cur.execute("SELECT * FROM employee;")

#Next you need to instruct Psycopg how to fetch your data
cur.fetchall()

#Finally, don't forget to close your cursor & connection
cur.close() 
conn.close()
