myFile = open("file.txt", "r")  
li = []
# Reading the file line by line and storing it in a list
for x in myFile:
    li.append(x.split(" "))

# Calculating sum of grades and printing name and sum.
for i in li:
    print("Name: ", i[0])
    index = 1
    sum = 0
    while (i[index] != "-999\n"):
        sum += int(i[index])
        index += 1
    print("Grade Sum: ", sum)

# Closing the file.
myFile.close()
