Swap Elements in a Python Tuple - Data Science Parichay

In this tutorial, we will look at how to swap two elements in a tuple in Python with the help of some examples.

Can you swap tuple elements?

No. Tuples are an immutable data structure in Python and thus cannot be modified after they are created. You can, however, create a new tuple with the required elements swapped.

Highlighted programs for you

Put simply, All Star is in the business of connecting students and schools. We help students find schools that are great matches for their educational needs, personal preferences and lifestyles, and schools pay us for our work.

Here's a quick Q & A of information we think you should know if you choose to use our websites. The main takeaways: Using our services is free, but starting and completing a degree, certificate or diploma program takes commitment and effort and should be considered carefully.

1. How do you provide your services for free?

Schools pay to advertise on our sites. This allows us to offer our service to prospective students like you for free.

Schools place a very high priority on enrolling students who go on to graduate. By using All Star's focused, information-rich services, schools can be more confident that the prospective students we introduce them to are truly committed to their education and to succeeding once they're enrolled in school.

2. How do you differ from your competitors?

There are other companies out there that do what we do. But there is no one that does it with more integrity or respect for our users and their choices. We put you, the student, in control. You get to choose the schools you're interested in, and you get to choose what programs you'd like to learn more about. We will never submit your contact information to a school without your consent.

3. Do you really work with ALL schools?

No. Our listings are not exhaustive, we do not list all schools, but they do include a rich selection of options. We believe this wide variety of options from hundreds of schools meets the needs of most prospective students who visit our sites. We partner with smaller schools that specialize in one particular career field, such as Pima Medical Institute, as well as world-class, multi-discipline institutions like the University of Southern California.

4. Is getting a degree really going to open up doors for me?

We really want you to succeed in the program you choose. So does your school. But we feel compelled to be very frank and upfront: You must work hard and stay committed to graduate. And assuming you do graduate, there is no guarantee you will find a job in your chosen field, or any job for that matter.

Obtaining an education has many personal benefits and can also improve your financial prospects. However, it's important to keep in mind that obtaining an education does not guarantee financial success or even a job. Job markets vary greatly by region, state, and even locally, and are affected by trends in the national economy and even international events. Other factors affecting your job-hunting success may include your job history and experience, and your level of education, degree, or certificate type. Your area of specialization plays a role, too.

5. If I do find a job, what can I expect in terms of salary?

The government publishes a great deal of information related to hundreds of jobs on the Bureau of Labor Statistics (BLS) website. We use this as a resource for many of the articles on the All Star websites. As comprehensive as the BLS information is, it is neither complete nor entirely accurate. The BLS salary information we publish is a national average. Actual salaries for a particular job or skill may be different where you live. For example, if you live in a large city or where the job market for particular skills is especially competitive, such as Silicon Valley in California, you're likely to receive a higher wage or salary for the same job than you would in a rural or economically depressed market. Other factors that can affect salary rates include the size of the employer, union contracts and governmental regulations to name a few.

6. Where are you located? How can I contact you?

All Star Directories is located at P.O. Box 1677 Renton, WA 98057. You can reach us at (206) 436-7500 or at customerservice@allstardirectories.com.

Create a list from the tuple elements.
Swap the relevant elements in the list using their index.
Create a new tuple from the list elements.

This will result in a new tuple with the required elements swapped from the original tuple.

Let’s now look at some examples of using this method.

Examples

Let’s create a tuple with three elements – 1, 2, and 3 and then use the above method to swap elements 2 and 3 and get a new tuple.

# create a tuple
t = (1, 2, 3)
# convert the tuple to list
ls = list(t)
# swap the elements in the list using their index
ls[1], ls[2] = ls[2], ls[1]
# create a new tuple from the list elements
new_t = tuple(ls)
# print the new tuple
print(new_t)

Output:

(1, 3, 2)

You can see that the required elements are swapped in the resulting tuple.

Let’s look at another example. This time we will swap the first two elements of a tuple with string values.

# create a tuple
t = ('Jim', 'Ben', 'Tom', 'Zack')
# convert the tuple to list
ls = list(t)
# swap the elements in the list using their index
ls[0], ls[1] = ls[1], ls[0]
# create a new tuple from the list elements
new_t = tuple(ls)
# print the new tuple
print(new_t)

Output:

('Ben', 'Jim', 'Tom', 'Zack')

The resulting tuple has the first two elements swapped from the original tuple.

FAQs

Can you swap two elements in a Python Tuple?

No. Tuples are immutable and thus cannot be modified after creation. You can create a new tuple with the elements swapped.

How to create a new tuple resulting from swapping two elements in the original tuple?

Create a list from the original tuple values, swap the relevant elements in the list using their index, and create a tuple from the list elements using the tuple() function.
