# Python | Find mixed combinations of string and list

| |

Method # 1: Using loop + ` enumerate () + replace () `
This task can be accomplished using a combination of the above functions. In this, we simply iterate over each element of the character list and insert each combination using brute force.

 ` # Python3 code to demonstrate how it works ` ` # Mixed combinations of string and list ` ` # using loop + enumerate () + replace () `   ` # initialize list and string ` ` test_list ` ` = ` ` [` ` "a" ` `, ` ` "b" ` `, ` ` "c" ` `] ` ` test_str ` ` = ` ` "gfg" `   ` # print original list and line ` ` print ` ` (` ` "The original list:" ` ` + ` ` str ` ` (test_list)) ` ` print ` ` (` `" The original string: "` ` + ` ` test_str) `   ` # Mixed combinations of line and list ` ` # using loop + enumerate ( ) + replace () ` ` res ` ` = ` ` [] ` ` for ` ` idx, ele ` ` in ` ` enumerate ` ` (test_str): ` ` ` ` res ` ` + ` ` = ` ` [test_str [: idx] ` ` + ` ` test_str [idx:] .replace (ele, k, ` ` 1 ` `) ` ` for ` ` k ` ` in ` ` test_list] `   ` # print result ` ` print ` ` (` ` "The list after mixed Combinations:" ` ` + ` ` str ` ` (res)) `

Output:

The original list: [’a’, ’b’, ’c’]
The original string: gfg
The list after mixed Combin ations: [’afg’, ’bfg’, ’cfg’, ’gag’, ’gbg’, ’gcg’, ’gfa’, ’gfb’, ’gfc’]

Method # 2: Using List Comprehension
The above functionality can be used to accomplish this task. In this, we provide a one-line alternative using comprehension.

 ` # Python3 code to demonstrate how it works ` ` # Mixed combinations of string and list ` ` # using comprehension list `   ` # initialize list and string ` ` test_list ` ` = ` ` [` ` "a" ` `, ` `" b "` `, ` `" c "` `] ` ` test_str ` ` = ` ` "gfg" `   ` # prints the original with squeak and string ` ` print ` ` (` ` "The original list: "` ` + ` ` str ` ` (test_list)) ` ` print ` ` (` ` "The original string:" ` ` + ` ` test_str) `   ` # Mixed combinations of line and list ` ` # using comprehension list ` ` res ` ` = ` ` [test_str [: idx] ` ` + ` ` ele ` ` + ` ` test_str [idx ` ` + ` ` 1 ` `:] ` ` ` ` for ` ` idx ` ` in ` ` range ` ` (` ` len ` ` (test_str)) ` ` for ` ` ele ` ` in ` ` test_list] `   ` # print result ` ` print ` ` (` ` "The list after mixed Combinations:" ` ` + ` ` str ` ` (res)) `

Output:

The original list: [’a’, ’b’, ’c’ ]
The original string: gfg
The list after mixed Combinations: [’afg’, ’bfg’, ’cfg’, ’gag’, ’gbg’, ’gcg’, ’gfa’, ’ gfb ’,’ gfc ’]
