Use the new matrix to create a new matrix again?

I have create a code where it takes numbers from my RangeInKM_Manufacturer array and subtract which each element in a matrix, and then creates a new matrix, this works good!

Now I want to use this new matrix and divide it by RangeInKM_By_Manufacturer and then multiply by 100 to get current percentage battery status, how do I do this?

My code: 

Electric_car = np.array({'Nissan Leaf 24 kWh pack', 'Nissan Leaf 30 kWh pack', 'Volkswagen e-Golf','Tesla Model S 90(D)','BMW i3 22kWh','BMW i3 33 kWh','KIA SOUL','Volkswagen e-Up(2016)','Renault ZOE R90 Z.E 40','Hyundai IONIQ','Mercedes-Benz B250E','Tesla model X 90D'});
RangeInKM_By_Manufacturer = np.array([199, 250, 300, 557, 190, 300, 250, 160, 403, 280, 200, 489])

City =     ['city1',       'city2',     'city3',      'city4',       'city5',  'city6',       'city7',      'city8' , 'city9', 'city10',   'city11','city12', 'city13',      'city14',        'city15',        'city16',    'city17', 'city18', 'city19',     'city20']
distances = [[0,             3.4,         4.5,           4,           5,       12.2,           5.4,          6.1,       5.7,     10.6,      12.8,    7.7,       7.4,           5,               12.4,             12.6,       8.7,      4.2,      3.8,         1.9],

 for EV_Start in RangeInKM_By_Manufacturer:
     for start_Driving in distances:
        Remaining_Range = [EV_Start-start_Driving]
     print(Remaining_Range)

I am thinking of create a new matrix called "SoC", and inside here I have something like this: [(Remaining_Range/RangeInKM_By_Manufacturer) * 100]

Am I thinking correct?

If I have understood it correctly, you want to divide Remaining_Range with RangeInKM_By_Manufacture and I will pick up from where you have left.

Your Remaining_Range looks like:

[array([ 487.1,  487.3,  485.6,  486.7,  485.7,  480.9,  485.2,  483.1,
         483.1,  478.6,  476. ,  480. ,  479.5,  483.3,  475.9,  479.4,
         479.1,  484. ,  484.2,  489. ])]

Since both the arrays you are trying to divide are not equal, let's first get them to a proper format else np.divide throws in errors.

Remaining_Range = np.array(Remaining_Range)
Remaining_Range = Remaining_Range.flatten()
RangeInKM_By_Manufacturer = np.array(RangeInKM_By_Manufacturer)
RangeInKM_By_Manufacturer = np.vstack(RangeInKM_By_Manufacturer)

Now perform the division:

SoC = np.divide(Remaining_Range, RangeInKM_By_Manufacturer)

This gives you values for each value in the Remaining_Range is divided by RangeInKM_By_Manufacturer. For example, 487.1/199, 487.3/199.......489/199. And then the cycle follows with each value from RangeInKM_By_Manufacture.

I am not sure what you mean by percentage but if you simply want to multiply this result by 100, then:

SoC = np.multiply(SoC, 100)

Is this what you expect?
