Why not use a one-liner?

>>> source = [[4, 1, False], [4, 2, False], [4, 3, False], [4, 4, False], [4, 5, False]]
>>> result = [x[1] for x in source]
>>> print result
[1, 2, 3, 4, 5]

hey priyanka
do one think :

list=[[4, 1, False], [4, 2, False], [4, 3, False], [4, 4, False], [4, 5, False]]
m=[]
for i in range(0,len(list)):
m.extend(list[0])
m=[4, 1, False, 4, 2, False, 4, 3, False, 4, 4, False, 4, 5, False]

thanks

Hi;

list= [[4, 1, False], [4, 2, False], [4, 3, False], [4, 4, False], [4, 5, False]]
my_list=[]
for object in list :
my_list.append(object[1])

print my_list # give [1, 2, 3, 4, 5]
