	THURSDAY EXERCISES

1. 
   User Input: ask a user for their favorite number, and save it to a text file.
   
2. 
   Data Dumping: Using the dictionary of following data, save the information to a csv file with the keys as the headers and the values as the rows of data:
   

>>> data = {
'name' : ['Dave', 'Dennis', 'Peter', 'Jess'],
'language': ['Python', 'C', 'Java', 'Python']
}

Today we learned how to work with text and CsV files. There are two methods for working with files, each has their own purpose, but generally the with statement is easier to work with.
Friday: Creating a User Database with CSV Files
For this week’s project, we’ll be building a replica of a user database with CSV files. We’ll be able to take input and allow users to log in/log out/register.
To follow along with this lesson, let’s continue from our previous notebook file
“Week_06” and add a markdown cell at the bottom that says, “Friday Project: Creating a
