Python Program to Read a List of Words and Return the Length of the Longest One

When it is required to read a list of words and return the length of the longest list, a method can be defined that iterates through the list and gets the length of every string in the list of strings using the ‘len’ method.

Below is a demonstration of the same −

Example

 Live Demo

def longest_length_string(my_string):
   len_str = len(my_string[0])
   temp_val = my_string[0]

   for i in my_string:
      if(len(i) > len_str):

         len_str = len(i)
         temp_val = i

   print("The word with the longest length is:", temp_val, " and length is ", len_str)

my_string = ["three", "Jane", "quick", "lesson", 'London', 'newyork']
print("The list is :")
print(my_string)
print("The method to find the longest string in the list is called")
longest_length_string(my_string)

Output

The list is :
['three', 'Jane', 'quick', 'lesson', 'London', 'newyork']
The method to find the longest string in the list is called
The word with the longest length is: newyork and length is 7

Explanation

• A method named ‘longest_length_string’ is defined.

• It takes a list of strings as a parameter.

• The list is iterated over, and the length of every string in the list is determined.

• The largest of these values is determined and returned as output.

• A list of strings is defined and is displayed on the console.

• The method is called bypassing this list as a parameter.

• The output is displayed on the console.
