The section ends with a discussion of closing a connection, e.g., using connection.close(). Is there also a command connection.open()? Look into the online documentation.

Create and edit a text file, named creds.json file, that follows the pattern in the book, which has a dictionary, and in that dictionary, there are entries for each of the remote or local database connections. Populate this file with the information specific to your environment. If you will only have a single database connection, your creds.json, at the outer level, will only have one element. Your file should be in a “known” location so that you can use it subsequently, like in a data directory for your work, or in the directory/folder where you will be executing your Python exercise code.

Human Resources Management (HRM)
I finished the first deliverable of a project presentation but had no time to finish my second deliverable. The writer revamped my first deliverable and made it much more appealing! Not only was I impressed with the content but I was so grateful for the time they took to redo the background. I have been under a lot of pressure at work and at home so this has been a great service when I have had little time! I appreciate the detail and help! Always on time and always exceeding expectations!

I am beyond eager to write this review for this writer. I received a grade of "Mastered"upon first submission on this assignment. I will shout to the rooftops ENCOURAGING you to hire him. I have used other writers but NONE have delivered such awesome work as this writer and NONE of their prices can compare to his. He does not try to "break the bank" and he works hard; it shows in the final paper and the grade. He is simply,THE BEST HERE!!
