expression (number, symbol, or nested list). The Tokenize function gets a series of lexical units that the read works by invoking the Read_from function on these lexical units. Given a list of lexical units, we first look at the first lexical unit; if it is a ', ' then this is a syntax error. If it's a ' (', then we start building an expression list until we read a matching ') '. All other (lexical units) must be symbols or numbers, which themselve

frequency distribution data. I will not introduce those methods here (refer to the probability tutorials listed in references ), it is enough to describe the fuzzy relationship between the expected ones and those you already know (not just the obvious scaling ratio/normalization. Basically, NLTK supports two types of frequency distribution: histogram and conditional frequency distribution ). The nltk. probability. FreqDist class is used to create a histogram. for example, you can create a word

based on these known frequency distributions. NLTK supports a variety of probabilistic prediction methods based on natural frequency distribution data. I will not introduce those methods here (see the probability tutorials listed in resources), as long as there is some ambiguity between what you are sure to expect and what you already know (more than the obvious scaling/normalization). Basically, NLTK supports two types of frequency distribution: histogram and conditional frequency distribution

simple tool: Python's str.split. We just add spaces around the brackets (in the source program), and then call Str.split to get a list of lexical units. Next comes the syntax analysis. We've seen that Lisp's syntax is simple. However, some Lisp interpreters allow you to accept any string representing the list as a program, making parsing easier. In other words, the string (set! 1 2) can be accepted as a syntactically valid program, and only when executed will the interpreter complain that the f
