Python's most efficient way to choose longest string in list?
From the Python documentation itself, you can use max:
>>> mylist = ['123','123456','1234']>>> print max(mylist, key=len)123456
What should happen if there are more than 1 longest string (think '12', and '01')?
Try that to get the longest element
max_length,longest_element = max([(len(x),x) for x in ('a','b','aa')])And then regular foreach
for st in mylist: if len(st)==max_length:...
def longestWord(some_list): count = 0 #You set the count to 0 for i in some_list: # Go through the whole list if len(i) > count: #Checking for the longest word(string) count = len(i) word = i return ("the longest string is " + word)or much easier:
max(some_list , key = len)
