def four_letter(wordList):
subList=[]#declare an empty list
#itreat through each word in the list
for word in wordList:
if(len(word)==4):#check the word length is 4 if it is 4 then append
the word in sublist

write a function firstLetterWords(words) that takes as a parameter a list of strings named words and returns a dictionary with lower case letters as keys. But now associate with each key the list of the words in words that begin with that letter. For example, if the list is ['ant', 'bee', 'armadillo', 'dog', 'cat'], then your function should return the dictionary {'a': ['ant', 'armadillo'], 'b': ['bee'], 'c': ['cat'], 'd': ['dog']}.

Write a function called most_consonants(words) that takes a list of strings called words and returns the string in the list with the most consonants (i.e., the most letters that are not vowels). You may assume that the strings only contain lowercase letters. For example: >>> most_consonants(['python', 'is', 'such', 'fun']) result: 'python' >>> most_consonants(['oooooooh', 'i', 'see', 'now']) result: 'now' The function that you write must use a helper function (either the num_vowels function from lecture, or a similar function that you...

Write the function deep_contains. It takes as input a number and a list. That list might contain lists as elements, and those lists might contain lists, etc. The deep_contains' function should return a Boolean indicating whether the number is contained inputted list, or a sublist of it, or a sublist of that, and so forth. For example: deep_contains (3, (1,3,5]) returns True deep_contains(3, 11, [3,5]]) returns True deep_contains (3, 1, [[3,4],5),6]) returns True deep_contains (2, (1,3,5]) returns False This function...

Write a recursive function recStringWithLenCount() that takes a
one-dimensional list of strings as a parameter and returns the
count of strings that have at least the length of second parameter
passed into the function that are found in the list. Recall that
you can determine whether an item is a string by writing type(item)
== str. The only list functions you are allowed to use are len(),
indexing (lst[i] for an integer i), or slicing (lst[i:j] for...
