convert multi list to one list !

[evilcode1]

hello all ...
this is my code :

#qassam = raw_input()


def loop():
        
    for i in range(12):
        qan = "Key.f{}".format(i+1)
        print qan.split()
'''
    if qassam in qan:
        print "yes"

    else:
        print "no"
'''





loop()

output :

Output:
['Key.f1']
['Key.f2']
['Key.f3']
['Key.f4']
['Key.f5']
['Key.f6']
['Key.f7']
['Key.f8']
['Key.f9']
['Key.f10']
['Key.f11']
['Key.f12']

i need to convert them to one list like [ 'Key.f1' , 'Key.f2' , 'Key.f3' ....ect ]
