Aug 29, 2022 · There's a simple iterator protocol that can be applied to any kind of object to make the for loop work on it. Simply implement an iterator that defines a next() method, and implement an __iter__ method on a class to make it iterable. (the __iter__ of course, should return an iterator object, that is, an object that defines next())

Oct 27, 2024 · The string len() function returns the length of the string. In this article, we will see how to find the length of a string using the string len() method. Example: [GFGTABS] Python s1 = "abcd" print(len(s1)) s2 = "" print(len(s2)) s3 = "a" print(len(s3)) [/GFGTABS]Outpu

Feb 24, 2025 · In this article, I explored g four different methods to get the length of a string in Python, such as using len() function, Iterating with a for loop and the in operator, combining join() and count() methods, and utilizing str.count().

Jan 28, 2025 · Python provides several ways to iterate through a string in Python. Let us see some important methods. Method 1. Use a For Loop. The simplest and most common way to iterate through a string in Python is by using a for loop. This method is simple and efficient. Here’s an example: print(char) Output:

Mar 7, 2021 · Using for loop to Find the length of the string in python. A string can be iterated over easily and directly in for loop. By maintaining a count of the number of iterations will result in the length of the string. counter = 0 . for i in str: . counter += 1. return counter . output:

I want to use for loop to extract string with a specific length before and after 'AAAA'. For example I want my output to be ['dkt', 'kgh', 'hui', 'ncg'] string.split('AAAA') can give me what I want but it does not give me strings with length of 3 character. I need to use for loop to generalize it.

Apr 6, 2018 · Python program to calculate length of a String without using len () function. First we will see how to find the length of string without using library function len (). Here we are taking the input from user and counting the number of characters in the input string using for loop.

May 24, 2023 · By using a for loop, you can iterate over the string and count the characters one by one. Example: my_string = "Fighting dragons is my hobby!" length = 0 for letter in my_string: length += 1 print (f "The length of my_string is {length}") Output:

Find Python String Length Using For Loop & in Operator. Using a for loop along with the in operator is a manual approach to finding the length of a string. This method iterates through each character in the string and counts them one by one.

Dec 22, 2024 · Using a for Loop to Find String Length in Python. An alternate way of finding the length of a string is by using a for loop and a counter variable initialized to 0. The method involves iterating through the string using the for loop and incrementing the counter in each iteration. Example: count = 0 # Iterate through the string. for t in ...
