 # 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 `]
