Question

USING PYTHON IDLE 3.4:

Question #8: You want to determine the distance to lightning strikes during a storm. This can be measured using the time elapsed between seeing the lightning flash and hearing the thunder. You know that the speed of sound is approximately 1,100 ft/second and 1 mile is 5,280 feet. Write a program named q8.py that prompts the user for the number of lightning strikes to analyze and the number of seconds between lightning and thunder. For each value entered, the program should calculate and print the distance to the lightning strike in miles. After all the time values are entered and the distances calculated, your program should display the average distance of all the strikes analyzed. Some example output your formatting might not be exactly as shown but should include the following: 2.5 sec 0.5208333333 333334 miles 1.25 sec 0.2604166666666 667 miles 5.4 sec 1.125 miles Total of 3 strikes, average distance of 0.6354166666666666 miles You may use any additional variable names you need, but your program should assign at least the following: number of lightning strikes total sum of all distance calculations average distance of all strikes average dist calculated distance of a single strike

NEED HELP WITH THIS PLEASE! :(

Solution: #intialize the list num array = list() #get the number of strikes to be analyzed nra inputc"Enter number of ightening atrikes to analyse:") #gets value3 of seconds print Enter the seconds: for i in range (int(n)) #computes the miles trave Iles based on the given second ral = ( (float (raw input (" ") ) ) *0.208) num array.append(float (val)) #displays the values after computing print The corresponding miles travelled: ',num array #calculate3 the average total 0 for elm in num array: total += elm attotal/ (len (num aa 1.0) print The averge miles travelied:avc Output sh-4.3$ python main-py Enter number of lightening strikes to analyse:3 Enter the seconds: 2.5 1.25 The corresponding miles travelled: [0.52, .26, 1.1232] The averge miles travelled: e.6344 sh-4.3

copyable code:

#intialize the list

num_array = list()

#get the number of strikes to be analyzed

n = raw_input("Enter number of lightening strikes to analyse:")

#gets values of seconds

print 'Enter the seconds: '

for i in range(int(n)):

    #computes the miles travelles based on the given second

    val = ((float(raw_input(" ")))*0.208)

    num_array.append(float(val))

#displays the values after computing

print 'The corresponding miles travelled: ',num_array

#calculates the average

total = 0

for elm in num_array:

     total += elm

avg=total/(len(num_array)*1.0)

print 'The averge miles travelled: ',+ avg
