Strings in Python are compared with Show
Often, when you’re working with strings in Python, you may want to compare them to each other. For example, you may want to compare a user’s email address against the one you have stored in a database when you are asking them to reset their password. Find Your Bootcamp Match

Python includes a number of comparison operators that can be used to compare strings. These operators allow you to check how strings compare to each other, and return a True or False value based on the outcome. This tutorial will discuss the comparison operators available for comparing strings in Python. We’ll walk through an example of each of these operators to show how they work, and how you can use them in your code. If you’re looking to learn how to compare strings in Python, this article is for you. Python String is and is Not Equal ToStrings are sequences of characters that can include numbers, letters, symbols, and whitespaces. Strings are an important data type because they allow coders to interact with text-based data in their programs. When you’re working with a string, you may want to see whether a string is or is not equal to another string. That’s where the The It’s important to note that string comparisons are case sensitive. So, lowercase letters and uppercase letters will affect the result of the comparisons you perform in your Python program. Let’s say that you are building a game that tests players on their knowledge of state capitals. In order to earn points, players must correctly answer a question. So, a player may be given the state California, and in order to gain points, they would need to enter that the capital is Sacramento into the program. Here’s an example of this guessing game application that compares a user’s answer to the answer stored by the program: random_state = "Delaware" message = "What is the capital of ", random_state user_answer = input(message) state_capital = "Dover" if user_answer == state_capital: print("You are correct!") else: print("The capital of ", random_state, "is", state_capital) Here’s what happens when we run our guessing game and correctly guess the state capital of Delaware is Dover: What is the capital of Delaware Dover You are correct! Our strings are equal, so our What is the capital of Delaware Denver The capital of Delaware of Dover Let’s break down our code. On the first one, we declare our random state, which in this case is
Delaware. Then, we use the user Our program then declares the state capital is Dover, and uses an When we entered Python is OperatorThe most common method used to compare strings is to use the The difference between Let’s use an example. Say that we have the scores of two users stored as a string, and we want to see whether or not they are the same. We could do so using the following code: player_one_score = "100" player_two_score = "100" if player_one_score is player_two_score: print("Player #1 and #2 have the same number of points.") else: print("Player #1 and #2 do not have the same number of points.") Our code returns: Player #1 and #2 have the same number of points. In the above code, we could also have used the The statement print(id(player_one_score)) print(id(player_two_score)) Our code returns: 140239618130992 140239618130992 As you can see, our objects are the same, and so the Python Other Comparison OperatorsIn addition, you can compare strings in lexicographic order using Python. Lexicographic order refers to ordering letters based on the alphabetical order of their component letters. To do so, we can use the other comparison operators offered by Python. These are as follows:
Let’s say we were creating a program that takes in two student names and returns a message with whose name comes first in the alphabet. We could use the following code to accomplish this task: student_one = "Penny" student_two = "Paul" if student_one > student_two: print("Penny comes before Paul in the alphabet.") elif student_one < student_two: print("Paul comes before Penny in the alphabet.") Our code returns: "Career Karma entered my life when I needed it most and quickly helped me match with a bootcamp. Two months after graduating, I found my dream job that aligned with my values and goals in life!" Venus, Software Engineer at Rockbot Paul comes before Penny in the alphabet. Let’s break down our code. On the first two lines, we declare two variables that store our student names. In this case, these names are Penny and Paul. Then, we create an if statement that uses the We also create an
In this case, Paul’s name comes before Penny’s in the alphabet, so the code in our ConclusionComparing two strings is an important feature of Python. For instance, you may be creating a login form that needs to compare the password a user has entered with the password they have set for their account. Python comparison operators can be used to compare strings in Python. These operators are: equal to ( You’re now ready to start comparing strings in Python like a pro! How do you compare letters in a string in Python?String comparison in python can be made both case sensitive(using == or !=) or case insensitive(using lower() or upper().
How do you compare letters in alphabet in Python?To compare strings alphabetically in Python, you can use the < (less than), > (greater than), <= (less than or equal to), and >= (greater than or equal to) operators. Note that uppercase letters come before lowercase letters. When working with strings, sometimes it can be useful to compare strings alphabetically.
How do you compare characters in Python list?Use sort() method and == operator to compare lists
The sorted list and the == operator are used to compare the list, element by element.
How do I find the difference between two characters in Python?How to get the difference between two strings in Python. string1 = "abc". string2 = "cdef". first_set = set(string1). second_set = set(string2). difference = first_set. symmetric_difference(second_set). print(difference). |
