Sometimes we come forward to the problem in which we receive a list that consists of strings and characters mixed and the task we need to perform is converting that mixed list to a list consisting entirely of characters. Let’s discuss certain ways in which this is achieved.
Here is an example Python program that converts a list of strings and characters to a list of characters:
def convert_to_char_list(lst): """ This function takes a list of strings and characters and returns a list of characters. Args: lst (list): A list of strings and characters. Returns: list: A list of characters. """ char_list = [] for item in lst: if isinstance(item, str): char_list += list(item) else: char_list.append(item) return char_list
The convert_to_char_list
function takes a single argument lst
, which is the list that needs to be converted. It initializes an empty list called char_list
, which will be used to store the converted characters.
The function then loops through each item in lst
. If the item is a string, the list
function is used to convert it to a list of characters, which are then added to char_list
using the +=
operator. If the item is not a string, it is simply appended to char_list
.
Finally, the function returns char_list
, which is the converted list of characters.
Here is an example usage of the function:
>>> lst = ['hello', 'world', '!', 'a', 'b', 'c'] >>> converted_lst = convert_to_char_list(lst) >>> print(converted_lst) ['h', 'e', 'l', 'l', 'o', 'w', 'o', 'r', 'l', 'd', '!', 'a', 'b', 'c']
In this example, the lst
contains a mixture of strings and characters. The convert_to_char_list
function is used to convert the list to a list of characters, which is then printed to the console.
