## Finishing the Matrix

Today, we finished the assignment over a matrix (2-dimensional array) in Python by calculating the ranking points for the teams in the FIRST Tech Challenge El Dorado League of North Texas for the 2017/2018 season.

As you may recall from the previous post titled “Continuing the Matrix“, when there is a tie in the qualifying points, the 3 highest ranking points for each team are summed together to break the tie. The team with the higher sum wins the tie-break.

I am going to remove lines 147 to 157 from last class, which was a test print and am going to replace them with the following to calculate the sum of the 3 highest ranking points.

```teams[0][13] = (teams[0][5] + teams[0][7] + teams[0][9] + teams[0][11]) - min(teams[0][5], teams[0][7], teams[0][9], teams[0][11])
teams[1][13] = (teams[1][5] + teams[1][7] + teams[1][9] + teams[1][11]) - min(teams[1][5], teams[1][7], teams[1][9], teams[1][11])
teams[2][13] = (teams[2][5] + teams[2][7] + teams[2][9] + teams[2][11]) - min(teams[2][5], teams[2][7], teams[2][9], teams[2][11])
teams[3][13] = (teams[3][5] + teams[3][7] + teams[3][9] + teams[3][11]) - min(teams[3][5], teams[3][7], teams[3][9], teams[3][11])
teams[4][13] = (teams[4][5] + teams[4][7] + teams[4][9] + teams[4][11]) - min(teams[4][5], teams[4][7], teams[4][9], teams[4][11])
teams[5][13] = (teams[5][5] + teams[5][7] + teams[5][9] + teams[5][11]) - min(teams[5][5], teams[5][7], teams[5][9], teams[5][11])
teams[6][13] = (teams[6][5] + teams[6][7] + teams[6][9] + teams[6][11]) - min(teams[6][5], teams[6][7], teams[6][9], teams[6][11])
teams[7][13] = (teams[7][5] + teams[7][7] + teams[7][9] + teams[7][11]) - min(teams[7][5], teams[7][7], teams[7][9], teams[7][11])
teams[8][13] = (teams[8][5] + teams[8][7] + teams[8][9] + teams[8][11]) - min(teams[8][5], teams[8][7], teams[8][9], teams[8][11])
teams[9][13] = (teams[9][5] + teams[9][7] + teams[9][9] + teams[9][11]) - min(teams[9][5], teams[9][7], teams[9][9], teams[9][11])
teams[10][13] = (teams[10][5] + teams[10][7] + teams[10][9] + teams[10][11]) - min(teams[10][5], teams[10][7], teams[10][9], teams[10][11])```

Let’s take a look at what we have going on here by just taking a look at the first line in this code segment:

`teams[0][13] = (teams[0][5] + teams[0][7] + teams[0][9] + teams[0][11]) - min(teams[0][5], teams[0][7], teams[0][9], teams[0][11])`

As you can see, we start by saying that we are going to populate column with 13 with some data. That data is the value of columns 5, 7, 9, & 11 added together and then the smallest of those values subtracted from that sum.

Remember, only the top 3 scores are used in the calculation and it we add the 4 scores together and then subtract the smallest (min) from that total, we get the data we need.

We now need to display our data.

```print(teams[0][0] + " - " + teams[0][1] + " - " + str(teams[0][12]) + " (" + str(teams[0][13]) + ")")
print(teams[1][0] + " - " + teams[1][1]  + " - " + str(teams[1][12]) + " (" + str(teams[1][13]) + ")")
print(teams[2][0] + " - " + teams[2][1]  + " - " + str(teams[2][12]) + " (" + str(teams[2][13]) + ")")
print(teams[3][0] + " - " + teams[3][1]  + " - " + str(teams[3][12]) + " (" + str(teams[3][13]) + ")")
print(teams[4][0] + " - " + teams[4][1]  + " - " + str(teams[4][12]) + " (" + str(teams[4][13]) + ")")
print(teams[5][0] + " - " + teams[5][1]  + " - " + str(teams[5][12]) + " (" + str(teams[5][13]) + ")")
print(teams[6][0] + " - " + teams[6][1]  + " - " + str(teams[6][12]) + " (" + str(teams[6][13]) + ")")
print(teams[7][0] + " - " + teams[7][1]  + " - " + str(teams[7][12]) + " (" + str(teams[7][13]) + ")")
print(teams[8][0] + " - " + teams[8][1]  + " - " + str(teams[8][12]) + " (" + str(teams[8][13]) + ")")
print(teams[9][0] + " - " + teams[9][1]  + " - " + str(teams[9][12]) + " (" + str(teams[9][13]) + ")")
print(teams[10][0] + " - " + teams[10][1]  + " - " + str(teams[10][12]) + " (" + str(teams[10][13]) + ")")```

Let’s take a look at what we have going on here by just taking a look at the first line in this code segment:

`print(teams[0][0] + " - " + teams[0][1] + " - " + str(teams[0][12]) + " (" + str(teams[0][13]) + ")")`

Here, we are displaying a concatenation of the team number from column 0, with a space/hyphen/space, with the team name from column 1, with a space/hyphen/space, with the sum of the qualifying points for the team from column 12, with a space, with the sum of the three highest ranking points in parenthesis from column 13.

The output should look like the following:

```Python 3.6.1 (default, Dec 2015, 13:05:11)
