Python array stores boolean value as an array

Question

I have the following python code which compares two numbers and stores either true or false in the array. However, in stead of storing it like this:

 [True, False, True....]

It stores it like this:

[array([ True]), array([ False]), array([ True])]

Here's the code:

def runSample(file_name):
    samples=open(file_name,'r').readlines()
    result=[]
    check = False
    for line in samples:
        data=json.loads(line);
        check=data[-1]==clf.predict([data[:-1]])
        result.append(check)
    print(result)

Why not perform all predictions at once?? Just filter None's and predict all valid data at once. Your current solution will be slow for a lot of data — yatu

Try

if check is not None:
    result.extend(check)

This will add check items to result

I accept this answer. Though it's a bit slower than append, but it does the job.
