I want to get a subarray in python 3. I have tried the following.

a = ['abcdefgh', 'abcdefgh' , 'abcdefgh'] print (a[0][3:6]) print (a[1][2:6]) print (a[0:2][3:6])

I get the first two results as expected. But I am not able to obtain the desired result for the 3rd print statement.

Output :

def cdef []

Desired Output :

def cdef ['def', 'def']

Can anyone tell me how to obtain it

Use list comprehension for this

print ([i[3:6] for i in a[0:2]])
0

This will work. It will iterate over elements at index 0 and 1 and will slice the array as expected. 

[x[3:6] for x in a[0:2]]
