Question

Python code question - you are given the grand prize(in USD) and the winning numbers.

Your program will read multiple tickets (6 selected numbers in each ticket) from the input file.

For each ticket, the program calculates its prize won, and outputs the prize (in USD) to the output file.

How to Play the Game?

In each ticket, the player selects five numbers from a set of 69 white balls (numbered 1 to 69)

and one number from 26 red balls (numbered 1 to 26).

The red ball number can be the same as one of the white balls, but a white ball can only be selected once.   

The order of selection does not matter.

The numbers in each ticket is not guaranteed to be sorted in any way.

Prize Rule:

The prize rule is given the figure below.

A ‘o means a white ball match and ‘x’ means the red ball match.

ooooox Grand Prize

ooooo $1,000,000

oooox $50,000

oooo     $100

ooox     $100

ooo       $7

oox       $7

ox          $4

x            $4

Input File: The input file is a text file (.txt).   

The first line contains only one number which is the grand prize.   

The second line contains exactly five numbers, separated by space characters, which are the five winning white balls.

The third line contains only one number which is the winning red ball.

Starting from the fourth line, each line contains exactly six numbers, separated by space characters, which represents a ticket.

The first five numbers are the selected white balls and the last number is the selected red ball.

You cannot assume how many tickets are in the input file.

No matter how many tickets are in the file, your program should read and process all of them.

The output file is a text file (.txt).

The first line contains a single number which is the calculated prize for the first ticket in the input file;

the second line contains a single number which is the calculated prize for the second ticket in the input file; and so on.

Since the prizes are represented in USD, you need to add a '$' before each number.

You can assume that the input file is error-free.

You do not need to consider how to deal with invalid inputs.

The input file is guaranteed to have no empty lines.

Code

def main():
winnigNumbers=[]
ticketNumbers=[]
# Open the file with read only permit
f = open('input.txt')
fw = open("output.txt", "w")
# use readline() to read the first line
grandPrice = f.readline().rstrip('\n\r')
lineNum=f.readline().split()
for num in lineNum:
winnigNumbers.append(int(num.rstrip('\n\r')))
winnigNumbers.append(int(f.readline().rstrip('\n\r')))
line= f.readline()
while line:
ticketNumbers=[]
lineNum=line.split()
countWhileMatchBall=0
for num in lineNum:
ticketNumbers.append(int(num.rstrip('\n\r')))
for i in range(len(ticketNumbers)-1):
for j in range(len(winnigNumbers)-1):
if(ticketNumbers[i]==winnigNumbers[j]):
