Как найти в текстовом файле строку по заданному критерию?

File1=open('file.txt','w')
n=int(input('input count of players\n'))
b=[ 'input number', 'input name', 'input role', input score']
a=[ ]
for i in range(n):
    for j in range(4):
        File1.write(input(b[j])
File1.close()

max=0
c=0
for i in range(n):
    for j in range(4):
        File.seek(4)
        If File.readline()>max:
            max=File.readline()
            c=i
print(c)

with open ('file.txt') as File:
    line_num = 0
    tmp_line = ''
    for line in File:
        line_num += 1
        if line_num % 4 > 0:
            tmp_line += line
        else:
            if line_num == 4 or line > max_l:
                max_l = line
                result = tmp_line + line
            tmp_line = ''
print(result)

def create_file(filename):
    out = open(filename, 'w')
    count = int(input('input count of players: '))
    tips = ['number: ', 'name: ', 'role: ', 'score: ']
 
    for i in range(count):
        data = [input(i) for i in tips]
        out.write('{}\n'.format(' '.join(data)))
    out.close()
 
 
def find_max(filename):
    return max(int(i.split()[-1]) for i in open(filename))
 
create_file('file.txt')
print(find_max('file.txt'))
