    print(lines)


fns = fn.replace('.txt', '_out.txt')
print(fns)

with open(fns, 'w+') as fs:
    print('name', 'sum', 'avg', file=fs)
    for l in lines:
        if l.startswith('name'):
            continue
        cols = l.split()
        name = cols[0]
        sum = float(cols[1])+float(cols[2])+float(cols[3])
        print(name, sum, sum/3, file=fs)
