We are developing a sports application. Our program should allow players to enter their names and score. The program will print player name and his average score. Output must meet the following requirements:The user name must be left-aligned. If the user name is fewer than 20 characters, additional space must be added to the right. The average score must be 3 places to the left of the decimal point and one place to the right of the decimal point ( like YYY.Y).

name=input('Enter Your Name:')
score=0
count=0
sum=0
while(score != -1):
score=int(input('Enter your scores: (-1 to end)'))
if score==-1:
break
sum+=score

break
else:
index += 1
