set comprehension
Much like list comprehension, set comprehension also allows to create a set with a single line of code. The only difference is the use of curly brackets
{} instead of [].s = set()
for i in range(10):
s.add(i**3)
print(s)s = {i**3 for i in range(10)}
print(s)Both of the programs will print exactly the same output:
{0, 1, 64, 512, 8, 343, 216, 729, 27, 125}.Challenge
Given
n words, you are asked to print all the unique last letters of those words in increasing order. To sort the set/list you can use the sorted() function.The input contains a single line of space-separated words.
The program should print a single line of space-separated unique letters in increasing order.
Input | Output |
abc def ghi | c f i |
hello, how are you doing? | , ? e u w |
Important: Use set comprehension to solve this challenge.
Can you solve this in a single line 😎?
