How to split list by certain repeated index in python

I have this list of decimal values

[97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112] // more and more...

How to split it in this way :

[[97,98,99,100],[101,102,103,104],[105,106,107,108],[109,110,111,112]]

then convert the decimal values to string so it can be like this

['abcd','efgh','ijkl','mnop']

>Solution :

You can do it with list comprehension:

a = [97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112]
[''.join(chr(j) for j in a[i:i+4]) for i in range(0, len(a), 4)]

Output:

['abcd', 'efgh', 'ijkl', 'mnop']
