Implement a python program to generate all possible permutations of a given string.

Question

Sure, here is a Python program to generate all possible permutations of a given string:
Python
def permutations(string):
  """
  Generates all possible permutations of a given string.
  Args:
    string: The string to generate permutations for.
  Returns:
    A list of all possible permutations of the string.
  """
  if len(string) == 0:
    return ['']
  permutations_list = []
  for i in range(len(string)):
    first_character = string[i]
    remaining_string = string[:i] + string[i + 1:]
    permutations_for_remaining_string = permutations(remaining_string)
    for permutation in permutations_for_remaining_string:
      permutations_list.append(first_character + permutation)
  return permutations_list
if __name__ == "__main__":
  string = "abc"
  permutations_list = permutations(string)
  print(permutations_list)
This program works by first checking if the string is empty. If the string is empty, then the program returns an empty list.
Otherwise, the program iterates through the characters in the string and calls the
permutations() function recursively. The permutations() function recursively generates all possible permutations of the remaining string. The program then appends each permutation to the
permutations_list.
Finally, the program returns the permutations_list.
To run the program, you can save it as a Python file and then run it from the command line. For example, if you save the program as
permutations.py, you can run it by typing the following command into the command line:
Code snippet
python permutations.py
This will print the list of all possible permutations of the string to the console.
Here is an example of the output of the program:
Code snippet
$ python permutations.py
['abc', 'acb', 'bac', 'bca', 'cab', 'cba']
As you can see, the output of the program is a list of all possible permutations of the string "abc", which is a total of 6 permutations.
