Write a program that reads the provided file station.csv text file for reading. It then scans the file for lines where the "DrainageAreaMeasure/MeasureValue" column IS NOT EMPTY, and writes those lines out to output file stations-filtered.csv file. Submit your source code and the filtered file. (station.csv file contains data with comma in the double quotes. Use this file, station_cleaned.csv for this problem.)

Write a program that reads in the file stations-filtered.csv and computes the average of the "DrainageAreaMeasure/MeasureValue" column and writes it to output file drainage-area-avg.txt

Write a program encodes a text file (a sample file) using a caesar cipher. It should take as input a shift value from 1-26 and the name of a text file, and write the encoded text to output fileciphertext.txt.To encode the file, add the shift value to the unicode value for each character, INCLUDING punctuation and whitespace. You are not required to decode the ciphertext version, but it does help for testing purposes.
