Python 3 Program - Write another program to read data from a file named Precipit

Question

Python 3 Program - Write another program to read data from a file named Precipitation.txt. The program will ask the user two questions and then will search through the data from the file (use lists) to pull only the data that applies. 1. The program will ask the user to select a month to determine maximum precipitation and then it will print the user’s month selection, the date of maximum precipitation in that month, and the amount of precipitation for that date as read from the data in the file. 2. The program will ask the user to select a month and will then determine the total and average precipitation for the month selected by the user. The program will print the month selected by the user, the average amount of precipitation during that month (formatted to 2 decimal places) and the total amount of precipitation during that month (formatted to 2 decimal places).

Explanation / Answer

'''

CODE IN PYTHON 2.7

FORMAT OF PRECIPITATION.TXT

YYYY-MM-DD:precipitation_value

Sample data of file:

2018-10-10:13.0444

2018-10-13:33.0334

2018-01-12:344.0

2018-02-12:12.0

2018-03-19:30.0
