+# Bus Fare Challenge - Week 1
+
+## Challenge
+
+Write a program that does the following:
+
+1. gets today's date and stores it in a variable `'date'`
+2. uses today's date to get the name on the day of the week written in short form with the first letter capitalized eg. `'Fri'` if today were Friday and assigns it a variable `'day'`
+3. uses if statements to determine the today's fare following these bus fare schedule:
+
+   - monday - friday --> 100
+   - saturday --> 60
+   - sunday --> 80
+4. Prints the results in this format  
+    >Date:    2021-01-05  
+    >Day:     Tue  
+    >Fare:    100  
+
+## Evaluation
+
+Run the [Checker](checker.py) file to evaluate your code. If all tests pass, your code will be the correct solution. If any fail, check the error messages and make changes to your code and repeat.
+
+## Note
+
+1. Your solution must be written in the [bus_fare_challenge](bus_fare_challenge.py) file and its name should never be changed.  
+2. Your program must make use of the following variable names:
+   - `'date'`
+   - `'day'`
+   - `'fare'`  
+*Failure to which all your tests will fail.*  
+3. The **Checker** file should **never** be **altered** at any cost.

 # CSV Files and Jupyter Notebooks
 
-CSV files are comma separated variable file. CSV files are frequently used to store data. In order to access the data in a CSV file from a Jupyter Notebook you must upload the file. 
+The so-called **CSV** (Comma Separated Values) format is the most common import and export format for spreadsheets and databases. The CSV format was used for many years prior to attempts to describe the format in a standardized way.
+
+Python has an in-built csv module which implements classes to read and write tabular data in CSV format.
+
+```python
+# format example
+>>> import csv
+>>> with open('./airports.csv') as file:
+...     data = csv.reader(file)
+...     for row in data:
+...     print(*row) # * is used to unpack lists
+Name City Country
+Seattle-Tacoma Seattle USA
+Dulles Washington USA
+Heathrow London United Kingdom
+Schiphol Amsterdam Netherlands
+Changi Singapore Singapore
+Pearson Toronto Canada
+Narita Tokyo Japan
+```
+
+A this module has a lot more features, checkout [more details](https://docs.python.org/3/library/csv.html).
