Strings in Python - Python Tutorial - w3Schools - Ch#09 English

Strings in python are surrounded by either single quotation marks, or double quotation marks. 'hello' is the same as "hello". Assigning a string to a variable is done with the variable name followed by an equal sign and the string. You can assign a multiline string to a variable by using three quotes Or three single quotes. Strings are Arrays Like many other popular programming languages, strings in Python are arrays of bytes representing unicode characters. 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. Looping Through a String Since strings are arrays, we can loop through the characters in a string, with a for loop. String Length To get the length of a string, use the len() function. Check String To check if a certain phrase or character is present in a string, we can use the keyword in. Check if NOT To check if a certain phrase or character is NOT present in a string, we can use the keyword not in.
