PYTHON ASSIGNMENT 10 - LIST COMPREHENSION
Write
a list comprehension that prints a list of the cubes of the numbers 1 through
10.
Write
a list comprehension that prints out the possible results of two coin flips (example
- one result would be ’ht’)
Write
a function that takes in a string and uses a list comprehension to return all
the vowels in the string.
Run
this list comprehension in your prompt:
[x+y
for x in [10, 20, 30] for y in [1, 2, 3]]
Write
a function that takes in a list of elements of different types and uses a list
comprehension to return all the elements of the list of type int. (Note: Use the
python isinstance function)

Two
words form a metathesis pair, if you can transform one into the other by
swapping two letters. Example – conserve and converse. Write a program to find
all the metathesis pair in a dictionary.

words are anagrams if you can rearrange the letters from one to spell the
other. Write a program that displays all lists of anagrams from the word list. Example:
[‘silent’,
‘listen’]

words are reverse pair, if each is the reverse of the other. Example: was and
saw. Write a program that finds all the reverse pairs in the word list.

words “interlock” if taking alternate letters from each forms a new word.
Example, “shoe” and “cold” interlock to form “schooled”. Write a program that
finds all pairs of words that interlock.
