q1 You have been asked to write a function that supplies the "reverse lookup" name for the person associated with a phone number. This means that given aphone number, you get the name of the person who is registered with that phone number.

Write a program to read the data from the file and produce the average temperature and average humidity for all the records in the file. This is a very large file - it is the actual temperature and humidity data from our server room. You would spend hours trying to do this manually, with a calculator, and you likely would make mistakes along the way. This is where computers are far superior to humans when dealing with boring, repetitive tasks. The output of the program will look like this: Average Temperature (C): NN.NNNNNNNNNNNNNN Average Humidity (%):…
