when I print longest in workspaces it has set longest to the My grandmother sentence so it is doing what I want
from functools import reduce
strings = [
"Do not take life too seriously. You will never get out of it alive.",
"My fake plants died because I did not pretend to water them.",
"A day without sunshine is like, you know, night.",
"Get your facts first, then you can distort them as you please.",
"My grandmother started walking five miles a day when she was sixty. She's ninety-seven know and we don't know where she is.",
"Life is hard. After all, it kills you.",
"All my life, I always wanted to be somebody. Now I see that I should have been more specific.",
"Everyone's like, 'overnight sensation.' It's not overnight. It's years of hard work.",
]
longest = reduce(lambda sent1, sent2: sent1 if sent1 > sent2 else sent2, [len(b) for b in strings])

But while your solution finds the length of the longest string, the instructions ask you to find the longest string itself.

Full Stack JavaScript Techdegree Student 22,669 Pointsi tried it this way: longest = reduce(lambda sent1, sent2: sent1 if len(sent1) > len(sent2) else sent2, [b for b in strings]) and when i print longest i still print the grandma sentence but it doesn't pass

Full Stack JavaScript Techdegree Student 22,669 Pointsas in print(longest) produces "My grandmother started walking five miles a day when she was sixty. She's ninety-seven know and we don't know where she is."

231,269 PointsWhile your code is meeting the requirements now, the challenge apparently doesn't like the list comprehension.
But since it doesn't do anything now anyway, just replace it with "strings" and you'll pass.
