Project in PythonWrite a program, world_cup.py, which reads in the results of the games in a particular group in the world cup in soccer and prints the results along with the table of standings (points, goals and goal difference) in the group. An example input file, groupA.txt,

isQatar;Ecuador;0;2

Senegal;Netherlands;0;2

Netherlands;Ecuador;1;1

Qatar;Senegal;1;3

Ecuador;Senegal;1;2

Netherlands;Qatar;2;0

Here can be seen, e.g., that Ecuador won Qatar 2-0, Netherlands and Ecuador made a draw 1-1, and Netherlands won Qatar 2-0.

The program starts by displaying the results in the following manner:

Enter filename: groupA.txt

Qatar 0:2 Ecuador

Senegal 0:2 Netherlands

Netherlands 1:1 Ecuador

Qatar 1:3 Senegal

Ecuador 1:2 Senegal

Netherlands 2:0 Qatar

Here, the first line is input. In the output that follows, the name of the first team is printed in a right-justified field of width 13.

When the results have been shown, the program asks if the table of standings should also been displayed. If the user does not answer with "y", then the program does not display anything more, but if the answer is "y", the table of standings is shown in the following manner:

When the results have been shown, the program asks if the table of standings should also been displayed. If the user does not answer with "y", then the program does not display anything more, but if the answer is "y", the table of standings is shown in the following manner:

Show standings? (y/n): y

Netherlands 7 5:1 4

Senegal 6 5:4 1

Ecuador 4 4:3 1

Qatar 0 1:7 -6

Three points are awarded for a win, one point for a draw, and 0 points for a loss. Here, it can be seen that Netherlands has seven points (2 wins and one draw), has scored five goals and conceded one, and its goal difference is four goals. The name of the team is printed in a left-justified field of width 13, the points in a right-justified field of width 2, the goals (x:y) in a right justified field of width 6, and the goal difference in a right-justified field of width 3. The input and output given the input file groupA.txt is then:

Enter filename: groupA.txt

Qatar 0:2 Ecuador

Senegal 0:2 Netherlands

Netherlands 1:1 Ecuador

Qatar 1:3 Senegal

Ecuador 1:2 Senegal

Netherlands 2:0 Qatar

Show standings? (y/n): y

Netherlands 7 5:1 4

Senegal 6 5:4 1

Ecuador 4 4:3 1

Qatar 0 1:7 -6
