Someone know more efficient way to find longest word ?

Question

txt = input().split()
length = {}
x = []
for word in txt:
length[len(word)] = word
x.append(len(word))
print(length[max(x)])

Help me to shorten this code😭😭

Answer 1

txt = input().split()
longest_word = max(txt, key=len)

Note that the key=len specifies that we must obtain the word depending on its length

Answer 2

Jayakrishna🇮🇳 ,

your sample code does not return the longest word as requested.

input of "aaaa xx" returns "xx".
for using max() with strings the result will be calculated lexicographically. so a string that starts with "x" is greater than a string that starts with "a".

for getting the longest word: see the sample of Abdelrahman Tlayjeh

Answer 3

Python has already a pre defined function for same purpose implementation:

print( max(input().split() ) )
edit: # print(max( txt, key=len) )

Answer 4

I seen it actually largest word. Not longest. And for same length string like above both approaches
["ab", "ad", "ac" ]
Op approach returns "ac"
And @Abdelrahman approach returns "ab" . It's fine for longest. But largest is actually "ad".
I only tested on this case. So waiting for response, it it also need largest. Or just need longest is enough.

Yes. I should mention it along.

Answer 5

print(max(input().split(),key=len))
this way you apply the max() function based on the length of the word with key=len
