Please solve in python, use a text file of 40 numbers first

Question 3 Sensor Frequency A scientist has done an experiment and collected a whole bunch of sensor readings. There could be upwards of 1000 readings in the file. The scientist is interested in the difference between the two most frequent readings that show up in the data. Write a program that will search through and analyze the data for him. Some rules: The first line of the file will contain the number of sensor readings. The readings are integer values, stored one per line in a file after that. If there is a tie for the most frequent reading, then use the largest one. If there is a tie for the second most frequent reading, then use the smallest one. If all the entries were unique then the difference is the largest reading subtract the smallest reading. You must design the algorithm yourself. You cannot use any utility in python that was not discussed in the lessons.
