Strings are ArraysLike many other popular programming languages, strings in Python are arrays of bytes representing unicode characters. Show
However, Python does not have a character data type, a single character is simply a string with a length of 1. Square brackets can be used to access elements of the string. ExampleGet the character at position 1 (remember that the first character has the position 0): a = "Hello, World!" Try it Yourself » I have a text file that consists of some text. I want to import this into an array consisting of characters, Ex: a file containing "Hello" would become

We will use some built-in functions and some custom codes as well. Let's first have a quick look over what is a string in Python. Python StringThe string is a type in python language just like integer, float, boolean, etc. Data surrounded by single quotes or double quotes are said to be a string. A string is also known as a sequence of characters.
Converting a string to a character array basically means splitting each character. This comma-separated character array will be a list of characters. List prints a string into comma-separated values. Each character will represent each index value. Let us look at the different ways below to convert a string to a character array. Example: Convert String to Character Array Using For loopThis example uses for loop to convert each character of string into comma-separated values. It prints a list of characters separated by a comma. It encloses the for loop within square brackets
Example: Convert String to Character Array Using listThis example uses
