Question

IN PYTHON PLEASE......

Process bowlers and their 3 bowling scores.

Use my data file below:

bowlers2.txt ( Showed below)

And you can also use a while loop to read your file if you prefer. How to average down an array, which you don’t have to do. In this case that would be the game 1 average for all bowlers for example.

Find the low average and high average.

Start with read the data into arrays/lists and printed out the arrays/lists to just make sure your program was working

You need to add one more array/list capable to holding decimal values. This array/list can be declared at the top of your code with the other arrays or below the previous code. You also need to add decimal variables for highscore and lowscore and string variables for highname and lowname.

Make a loop to go through your arrays one row at a time. Each time through the loop add up the 3 scores of each bowler and divide that total by 3.0 to get the average. Put the average in the new array for that bowler. When you are finished with the loop, each bowler will have an average.

Now find the highest and lowest average. You can use a sequential search. You can’t just sort the average array, because then the averages would not match up with the correct names in the names array and you have to print out the lowest average with that person’s name, and same thing for highest average.

To find ″keith hallmark’s″ average you would have to input ″keith hallmark″ from the keyboard first.(You are assuming you want this to work for any bowler.)

And since the names in the names array are in a variety of cases, I would covert the name entered from the keyboard (keith hallmark) to upper case.

Then I would loop through the name array one row at a time, comparing the name entered from the keyboard to the names in the names array, but you would also have to convert the name in the names array to uppercase before making the comparison. Don’t permanently change the name in the names array, just convert it to uppercase for comparison. Don’t forget that in Java you have to use a function for comparison.

Once you find a match on the keith hallmark, print out his name and average. At that point you could use the break function to exit the loop. If keith hallmark is in row 7 of the names array, his average would be in row 7 of the average array.

You are only printing to the screen, not to a file of any kind.

Answer 1

Source Code in Python:

fin=open('bowlers2.txt','r') #opening file in read mode
names=[] #empty list to store names
averages=[] #empty list to store averages
name=' '
while name!='':
name=fin.readline() #reading a name
if name!='': #if name is not blank
average=(int(fin.readline())+int(fin.readline())+int(fin.readline()))/3 #calculating average for the player
names.append(name[:len(name)-1]) #indexing to remove the \n
averages.append(average)
#calculating minimum and maximum average
max=0
min=0
for i in range(1,len(averages)):
if averages[i]>averages[max]:
max=i
if averages[i]<averages[min]:
min=i
print(names[min],averages[min]) #output
print(names[max],averages[max]) #output

1 fin open("bowlers2 . txt','r') #opening file in read mode 2 names [ #empty List to store names 3 averages-[] #empty List to store averages 4 name 5 while name!' name-fin.readline #reading if name! : #if name is not blank average-(int(fin . readline ( ) ) +int (fin . readline ())+int (fin . readline () ) ) /3 names.append(name [:len (name)-1]) #indexing to remove the In averages.append (average) 6 a name 7 8 #calculating average for the pla 9 10 11 #calculating minimum and maximum average 12 max-e 13 min e 14 for i in range (1, len (averages)) 15 if averages[i] >averages [max] max-i 16 if averages[i]<averages [min]: min-i 17 18 19 print(names [min],averages[min]) #output 20 print(names [max],averages[max]) #output

Output:
