Массивы? Список? Сохранение значений (x,y) для каждой строки

Question

Есть ли способ на Python создать какой-то массив для присвоения значений x и y каждой строке в файле каждый раз, когда он разбивается?

myArray=[][]?

говорят линии

0.0 0.0 NaN  ( I want this line to have value[1,1]

1.0 0.0 1.0  (and so increasing y by one leaving x alone [1,2]

2.0 0.0 NaN  ---[1,3]

3.0 0.0 NaN---[1,4]

0.0 1.0 2.0---(but when the middle term changes value (increase x by 1 and reset y to 1 leaving [2,1])

1.0 1.0 3.0---[2,2]

2.0 1.0 4.0---[2,3]

3.0 1.0 NaN--- and so on

0.0 2.0 5.0

1.0 2.0 6.0

2.0 2.0 7.0

3.0 2.0 NaN

0.0 3.0 NaN

1.0 3.0 NaN

2.0 3.0 8.0

3.0 3.0 9.0

0.0 4.0 NaN

1.0 4.0 NaN

2.0 4.0 NaN

3.0 4.0 10.0  ---[4,4]

Имеет ли это смысл того, что я спрашиваю? Есть ли способ сделать это?

# read data

new_results = []

value = [0,0]

for row in results:
    if row[1] != middle:
        middle = row[1]
