I am writing this machine learning code (classification) to clssify between two classes. I started by having one feature to capture for all my images.

for example:

class A=[(4295046.0, 1), (4998220.0, 1), (4565017.0, 1), (4078291.0, 1), (4350411.0, 1), (4434050.0, 1), (4201831.0, 1), (4203570.0, 1), (4197025.0, 1), (4110781.0, 1), (4080568.0, 1), (4276499.0, 1), (4363551.0, 1), (4241573.0, 1), (4455070.0, 1), (5682823.0, 1), (5572122.0, 1), (5382890.0, 1), (5217487.0, 1), (4714908.0, 1), (4697137.0, 1), (4737784.0, 1), (4648881.0, 1), (4591211.0, 1), (4750706.0, 1), (5067788.0, 1), (7392115.0, 1), (7024501.0, 1), (6590118.0, 1), (6260326.0, 1), (6001223.0, 1), (5513267.0, 1), (5684732.0, 1), (4092011.0, 1), (6634798.0, 1), (6885369.0, 1), (2854799.0, 1), (2642866.0, 1), (2591293.0, 1), (2345370.0, 1), (2353085.0, 1), (2598480.0, 1), (3996284.0, 1), (7536032.0, 1), (7338023.0, 1), (7561037.0, 1), (7529364.0, 1), (7577504.0, 1), (7353176.0, 1), (4057898.0, 1), (4143981.0, 1), (3899129.0, 1), (3830584.0, 1), (3557377.0, 1), (3125518.0, 1), (3197039.0, 1), (3109404.0, 1), (3024219.0, 1), (3066759.0, 1), (2726363.0, 1), (3507626.0, 1), (2531828.0, 1), (2330385.0, 1), (2317570.0, 1), (2444669.0, 1), (2513998.0, 1), (2624739.0, 1), (3555578.0, 1), (2582228.0, 1), (4404128.0, 1), (4307425.0, 1), (4188310.0, 1), (2460042.0, 1), (4387062.0, 1), (2162785.0, 1), (2168945.0, 1), (2304868.0, 1), (2437261.0, 1), (3557410.0, 1), (3830618.0, 1), (3550021.0, 1), (3588758.0, 1), (3447567.0, 1), (3559924.0, 1), (3284499.0, 1), (3595260.0, 1), (4494963.0, 1), (4294039.0, 1), (3849395.0, 1), (3620279.0, 1), (3406951.0, 1), (3578885.0, 1), (3763810.0, 1), (3820821.0, 1)]

rest of my code:

//data is A and B combined

x = [[each[0]] for each in data]
y = [[each[1]] for each in data]
print (len(x), len(y))

x_train, x_test, y_train, y_test = train_test_split(x, y, test_size=0.2, random_state=42)
print (len(x_train), len(x_test))
print (len(y_train), len(y_test))

from sklearn.ensemble import RandomForestClassifier

clf = RandomForestClassifier(n_estimators=100, max_depth=2, random_state=0)
clf.fit(x_train, y_train)

Question:

what to change to add another feature? how the A and B should look like and how the classifier should look like? [Python]
