Python expressiveness

Here i will post my solution of the first two problems in the qualifying round in the Google Code Jam. Both are easy problems.

The first one is:

https://code.google.com/codejam/contest/2974486/dashboard#s=p0

#!/usr/bin/python

def read_board(row_number):
    for i in xrange(4):
        if i + 1 == row_number:
            row = map(int, raw_input().split(' '))
        else:
            raw_input()
    return row 

ncases = int(raw_input())

for ncase in xrange(ncases):
    first_row_number = int(raw_input())
    first_row = read_board(first_row_number)

    second_row_number = int(raw_input())
    second_row = read_board(second_row_number)
    match_count = 0
    number = 0
    for i in first_row:
        for j in second_row:
            if i == j:
                number = i
                match_count += 1
                break

    answer = 'Case #' + str(ncase + 1) + ': '
    if match_count == 0:
        print answer + 'Volunteer cheated!'
    elif match_count == 1:
        print answer + str(number)
    else:
        print answer + 'Bad magician!'

And the other one was https://code.google.com/codejam/contest/2974486/dashboard#s=p1:

#!/usr/bin/python

ncases = int(raw_input())

for ncase in xrange(ncases):
    data = map(float, raw_input().split(' '))
    C, F, X = tuple(data)

    if X <= C:
        print 'Case #' + str(ncase + 1) + ': ' + str(X/2.0)
    else:
        house_times = [C/2.0]
        cookies_per_second = [2.0]
        min_time = X/2.0

        for i in xrange(int(X)/int(C)):
            new_cookies_per_second = cookies_per_second[i] + F
            new_time = house_times[i] + X/new_cookies_per_second
            house_times.append(house_times[i] + C/new_cookies_per_second)
            cookies_per_second.append(new_cookies_per_second)

            min_time = min(min_time, new_time)

        print 'Case #' + str(ncase + 1) + ': ' + str(min_time)
