From the three Sentences find the word whose number of the letters is given
On this page: .split(), .join(), and list().
Splitting a Sentence into Words: .split()Below, mary is a single string. Even though it is a sentence, the words are not represented as discreet units. For that, you need a different data type: a list of strings where each string corresponds to a word. .split() is the method to use:>>> mary = 'Mary had a little lamb' >>> mary.split() ['Mary', 'had', 'a', 'little', 'lamb'] Show
Splitting on a Specific SubstringBy providing an optional parameter, .split('x') can be used to split a string on a specific substring 'x'. Without 'x' specified, .split() simply splits on all whitespace, as seen above.String into a List of Characters: list()But what if you want to split a string into a list of characters? In Python, characters are simply strings of length 1. The list() function turns a string into a list of individual letters:>>> list('hello world') ['h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd']More generally, list() is a built-in function that turns a Python data object into a list. When a string type is given, what's returned is a list of characters in it. When other data types are given, the specifics vary but the returned type is always a list. See this tutorial for details. Joining a List of Strings: .join()If you have a list of words, how do you put them back together into a single string? .join() is the method to use. Called on a "separator" string 'x', 'x'.join(y) joins every element in the list y separated by 'x'. Below, words in mwords are joined back into the sentence string with a space in between:>>> mwords ['Mary', 'had', 'a', 'little', 'lamb'] >>> ' '.join(mwords) 'Mary had a little lamb'Joining can be done on any separator string. Below, '--' and the tab character '\t' are used. >>> '--'.join(mwords) 'Mary--had--a--little--lamb' >>> '\t'.join(mwords) 'Mary\thad\ta\tlittle\tlamb' >>> print('\t'.join(mwords)) Mary had a little lambThe method can also be called on the empty string '' as the separator. The effect is the elements in the list joined together with nothing in between. Below, a list of characters is put back together into the original string: >>> hi = 'hello world' >>> hichars = list(hi) >>> hichars ['h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd'] >>> ''.join(hichars) 'hello world' This article is based on Free Code Camp Basic Algorithm Scripting “Find the Longest Word in a String”. In this algorithm, we want to look at each individual word and count how many letters are in each. Then, compare the counts to determine which word has the most characters and return the length of the longest word. In this article, I’m going to explain three approaches. First with a FOR loop, second using the sort() method, and third using the reduce() method. Algorithm ChallengeReturn the length of the longest word in the provided sentence. Provided test cases
1. Find the Longest Word With a FOR LoopFor this solution, we will use the String.prototype.split() method
We will need to add an empty space between the parenthesis of the split() method,
which will output an array of separated words:
If you don’t add the space in the parenthesis, you will have this output:
Without comments:
2. Find the Longest Word With the sort() MethodFor this solution, we will use the Array.prototype.sort() method to sort the array by some ordering criterion and then return the length of the first element of this array.
In our case, if we just sort the array
we will have this output:
In Unicode, numbers come before upper case letters, which come before lower case letters. We need to sort the elements by some ordering criterion,
where the length of the second element is compared to the length of the first element in the array.
Without comments: 03. Find the Longest Word With the reduce() MethodFor this solution, we will use the Array.prototype.reduce().
reduce() executes a callback function once for each element present in the array. You can provide an initial value as the second argument to reduce, here we will add an empty string “”. 1 2Without comments: 3I hope you found this helpful.
