#Lisp function to convert string to list how to#

In this guide, we are going to take a deep dive into the world of string manipulation in Lisp. While it might not be as prominent as languages like Python or Java in the current programming landscape, Lisp's influence is widespread, particularly in the fields of artificial intelligence, machine learning, and data science. It's primarily known for its effective symbolic expression and the capability to easily create complex AI algorithms. Developed in the late 1950s, Lisp is one of the oldest high-level programming languages that is still in use today. Our focus in this guide is the Lisp programming language. Whether we're developing complex web applications, performing data analysis, or implementing AI algorithms, string manipulation is an essential skill to have under our belt. A string, simply put, is a sequence of characters. Of these, one that consistently plays a pivotal role across various applications is the ' string'. In the fascinating realm of programming, we constantly come across diverse data types. Common Lisp has both strings and characters in addition to symbols.Welcome to 'Strings Attached: An In-Depth Exploration Of Lisp String Manipulation Techniques'. Historically, very old Lisp implementations did not have strings or characters as types, so symbols were used as a crude substitute. The characters that the programmer typed to refer to this symbol object have gone away by the time your program runs. You can only get the letter 'H' by finding that it is an element of the string which is the name of the symbol. Under the covers it is more like a unique memory address in your Lisp image: a 64-bit number.

You can't open this object up and see letters inside. It is called an 'atom' because it does not really have component parts. Symbols in Common Lisp are called atoms because they are objects on their own, and are usually 'interned' so that the name of the symbol (including the package name) refers to one and only one symbol. Or take you and split you up into characters 'g' 'u' 'm' 'm' 'y' 'b' 'e' 'a' 'r' 'd' 'i' 'e' 't.' Some people have given examples using SYMBOL-NAME, but that is ignoring an important issue by blurring the crucial distinction between a 'thing' and 'the name we call the thing.' It's similar to the idea that you take the number 123 and break it into the digits 1, 2, and 3. Your guess that it is 'contrary to how Lisp works' is a pretty good one.
