how to access and print the value of inner index in python list

I have a list of strings i will like to access and print its inner elements as shown below:

mylist = ['apple', 'balls', 'camera', 'dough', 'eleven']
specified_index = random.choices((range(len(mylist))), k=len(mylist))
print("specified_index =", specified_index)
merged_index = [mylist[tt] for tt in specified_index]
print("merged_index =", merged_index)

The result of merged_index keeps printing the words found at specified_index. Sample Output:

specified_index = [2, 3, 4, 0, 1]
merged_index = ['camera', 'dough', 'eleven', 'apple', 'balls']

What i want instead is to keep printing the corresponding letter of specified_index -not the whole words even if the list is shuffled. #For example: My preferred output == "mgeaa"

specified_index = [2, 3, 4, 0, 1]
merged_index = ['caMera', 'douGh', 'elevEn', 'Apple', 'bAlls']

Note::: I tried

import more_itertools as mit
merged_list = mit.random_product(mylist)

but it doesn't allow me to maintain same specified_index whenever mylist is shuffled #Other answers i found does not really solve this.

Assuming all the words in mylist are longer than or equal to the length of mylist a list comprehension could be used to achieve your desired result:

>>> import random
>>> mylist = ['apple', 'balls', 'camera', 'dough', 'eleven']
>>> specified_index = random.choices((range(len(mylist))), k=len(mylist))
>>> specified_index
[2, 3, 4, 0, 1]
>>> merged_index = [f'{mylist[i][:i]}{mylist[i][i].upper()}{mylist[i][i+1:]}' for i in specified_index]
>>> merged_index
['caMera', 'douGh', 'elevEn', 'Apple', 'bAlls']
>>> merged_word = ''.join(mylist[i][i] for i in specified_index)
>>> merged_word
'mgeaa'

As an aside, since python employs duck typing using Hungarian notation for variables in Python (mylist) is kinda sus ngl... consider using words or something else that doesn't reference the type next time fr fr.

You need to access each element in mylist at the same time as iteration through specified_index. You can do that with zip. Then use ''.join to get the desired result.

mylist = ['apple', 'balls', 'camera', 'dough', 'eleven']
specified_index = random.choices((range(len(mylist))), k=len(mylist))
print("specified_index =", specified_index)
merged_index = ''.join([elem[tt] for elem, tt in zip(mylist, specified_index)])
print("merged_index =", merged_index)

specified_index = [2, 0, 0, 2, 4]
merged_index = pbcue
