Converting each element in a list to a string: Employ list comprehension Using list comprehensions lets you convert each element in the list to a string. num_list = [1, 2, 3] str_elements = [str(element) for element in num_list] print(str_elements) # Output: ['1', '2', '3']...
We can convert it to the list of characters using list() built-in function. When converting a string to list of characters, whitespaces are also treated as characters. Also, if there are leading and trailing whitespaces, they are part of the list elements too. s = 'abc$ # 321 ' ...
