Use Python for this question: Write a standalone function partyVolume() that takes accepts one argument, a string containing the name of a file. The objective of the function is to determine the a Volume object that is the result of many people at a party turning the Volume up and down. More specifically: the first line of the file is a number that indicates the initial value of a Volume The remaining lines consist of a single character followed by a space followed by a number. The character will be one of ‘U” or ‘D’ which stand for “up” and “down” respectively. The function will create a new Volume object and then process each line of the file by calling the appropriate method of the Volume object which changes the value of the Volume. The function then returns the final Volume object. Guidelines/hints: This is a standalone function, it should NOT be inside (indented within) the class. It should be listed in the module after the Volume class and without indentation. Note that the first line of the file will be treated differently than all the other lines. Probably the easiest way to do this is to 1) open the file, 2) call the .readline() method (no s!) which reads a single line, the initial value of the Volume, then 3) call the .readlines() method which reads the rest of the lines. Item 2) will be used to set the initial Volume and 3) will be iterated over to represent turning the volume up and down some number of time. Make sure you return the final Volume Returned output for this question: ##### partyVolume ##### >>> partyVolume('party1.txt') Volume(6.35) >>> partyVolume('party2.txt') Volume(3.75) >>> partyVolume('party3.txt') Volume(0.75) # make sure return not print >>> partyVolume('party1.txt')==Volume(6.35) # return not print True >>> partyVolume('party2.txt')==Volume(3.75) True >>> partyVolume('party3.txt')==Volume(0.75) True
