Python
This is the code we are using:
def main ():
video_file = open ( 'video_times.txt')
list = []
for line in video_file:
run_time = float(line)
list.append (run_time)
print ('Video #', ':', run_time)
print(list)
sum = 0
for i in range(len(list)):
sum = sum + list[i]
video_file.close
main ( )
The following text is read from the video_times.txt file:
Video # 1 : 10.0
Video # 2 : 24.5
Video # 3 : 12.2
Video # 4 : 14.6
Video # 5 : 20.4
Video # 6 : 22.5
Video # 7 : 19.3
Video # 8 : 18.6
Video # 9 : 17.5
Video # 10 : 14.8
Video # 11 : 12.2
How do I change the code so that the total running time and average running time is displayed at the end of this output? We need to sum the times and figure out the average.
The total running time is 186.6 seconds
The average running time is 16.963636363636365
