Are you tired of seeing brackets, commas or quotes every time you print a list of integers? Do you wish there is a simpler way to do it? Well, you’re in the right place! In this article, we’ll teach you how to print integer lists without all the unwanted characters. You’ll be surprised at how easy it is!Firstly, let’s identify the problem. When we print a list of integers in Python, the default output format includes brackets, commas and quotes. While these characters are useful in certain circumstances, they can be quite distracting when you just need a plain list of numbers. Fortunately, Python provides several options to customize the output format of lists, and we’ll show you how to use them step by step.So, get ready to say goodbye to brackets, commas and quotes, and hello to clean and simple integer lists. Whether you’re a seasoned developer or a newbie in Python programming, this guide is for you. Follow along and learn how to impress your colleagues with your newfound knowledge. Don’t miss out on this opportunity to enhance your coding skills!
“How To Print A List With Integers Without The Brackets, Commas And No Quotes? [Duplicate]” ~ bbaz
The Need for Printing Integer List Without Brackets, Commas or Quotes
Printing a list of integers without brackets, commas or quotes is sometimes necessary. This could be because you need to pass the data to a function that expects digits only but not a list object with formatting. It can also be more visually pleasing to have the numbers printed out in a straight line without the clutter of unnecessary formatting. There are different ways to print an integer list without these extras and this guide will walk you through some options.
Using Join() Function
The join() function is a built-in Python function that can be used to concatenate strings. You can use it to convert a list of integers to a single string without formatting characters. To do so, you can simply write:
“`pythonmy_list = [1, 2, 3, 4, 5]print(‘ ‘.join(map(str, my_list)))“`
The output will be:
1 2 3 4 5
Explanation
The join() function takes a separator as an argument, which is a space in this case. The map() function is used to apply the str() function to every element of the list to convert them to strings before they are joined together.
The Commaless Print Statement
You can also use the comma operator in Python’s print statement to print integers without commas.
“`pythonmy_list = [1, 2, 3, 4, 5]print(*my_list)“`
The output will be:
1 2 3 4 5
Explanation
The print() statement accepts multiple arguments which are printed out separated by a space. The asterisk (*) operator here is used to unpack the list, leaving only the individual elements separated by spaces.
The Reduce() Function
The reduce() function from Python’s functools module can be used to convert a list of integers to a single integer value. It works by applying a given function (in this case, lambda x, y: int(str(x) + str(y))) to every element of the list to combine them into a single integer,
“`pythonfrom functools import reducemy_list = [1, 2, 3, 4, 5]print(reduce(lambda x, y: int(str(x) + str(y)), my_list))“`
The output will be:
12345
Explanation
The reduce() function uses a lambda function that converts two elements of the list into strings before concatenating them together and converting the resulting string back to an integer. This process continues until all the elements are concatenated into a single integer.
Time Comparison Table
Here is a table comparing the three methods of printing integers without commas, quotes or brackets:
| Method | Code | Time Complexity |
|---|---|---|
| Join() function | ‘ ‘.join(map(str, [1, 2, 3, 4, 5])) | O(n) |
| Commaless print statement | print(*[1, 2, 3, 4, 5]) | O(n) |
| Reduce() function | reduce(lambda x, y: int(str(x) + str(y)), [1, 2, 3, 4, 5]) | O(nlogn) |
Conclusion
The methods presented in this guide offer a range of options for printing integer lists without commas, quotes or brackets. Though some methods may be more efficient than others, the choice of which method to use may depend on various factors such as readability, space and other requirements of your program.

Printing integer list without brackets, commas, or quotes may seem like a daunting task for some. Below are some common questions people ask about this topic along with their corresponding answers:
-
What is an integer list?
An integer list is a collection of integers, which are whole numbers without decimals or fractions.
-
Why would I want to print an integer list without brackets, commas, or quotes?
There are a variety of reasons why you may want to do this. For example, if you are working with programming languages such as Python or Java, you may need to format your output in a certain way without any extraneous characters.
-
How can I print an integer list without brackets, commas, or quotes?
There are different approaches to achieve this, depending on the programming language you are using. However, one common way is to use a loop to iterate over the elements of the list and concatenate them into a string. For instance, in Python, you could do:
my_list = [1, 2, 3, 4, 5]output = for i in my_list: output += str(i)print(output)This would print:
12345 -
Is there a way to do this without using a loop?
Yes, some programming languages have built-in functions to achieve this. For example, in Python, you could use the join() function to concatenate the elements of a list into a string without any separator. Like this:
my_list = [1, 2, 3, 4, 5]output = .join(map(str, my_list))print(output)This would also print:
12345
