We define a paragraph as a string formed by joining a nonempty sequence of nonseparator lines, separated from any adjoining paragraphs by nonempty sequences of separator lines. Each line is terminated with a special character, called the EOL or End of Line. Functions are a convenient way to divide your code into useful blocks, allowing us to order our code, make it more readable, reuse it and save some time. Right now I’m working on my own book aimed at advancing Python programmers. This reduces the length of the URLs needed to refer to related documents, and allows document trees to be accessed via multiple access schemes (e. The command “wc” basically means “word count” and with different optional parameters one can use it to count the number of lines, words, and characters in a text file.
