4a06566e4a32/ String: A sequence of characters enclosed within single or double quotes. A string can include any character, including special characters and spaces. Examples: "Hello World!", 'I have $250 cash and a credit card.' Note: Each character in a string falls in a specific position, so we can assign an index (numbering) to each character. Such assignment helps us to perform mathematical operations on strings. Operations: * finding characters by position, length of string, concatenating, replicating, slicing * Back slashes for escape sequences: new line, tab * String methods: upper, replace, substrings, raw strings CSCI 1321: Introduction to Programming Using Python and R
