How to Print a Tuple Without Parentheses in Python?

Problem Formulation

Given a tuple of elements. If you print the tuple to the shell using print((1, 2, 3)), the output is enclosed in parentheses like so: (1, 2, 3). But you want the list without brackets like so: 1, 2, 3.

print((1, 2, 3))
# Output: (1, 2, 3)
# Desired: 1, 2, 3

How to print the tuple without enclosing parentheses?

Method 1: Unpacking

The asterisk operator * is used to unpack an iterable into the argument list of a given function. You can unpack all tuple elements into the print() function to print each of them individually. Per default, all print arguments are separated by an empty space. For example, the expression print(*my_tuple) will print the elements in my_tuple, empty-space separated, without the enclosing parentheses!

my_tuple = (1, 2, 3)
print(*my_tuple)
# Output: 1 2 3

Method 2: Unpacking with Separator

To print a comma-separated tuple without enclosing parentheses, the most Pythonic way is to unpack all tuple values into the print() function and use the sep=', ' argument to separate the tuple elements with a comma and a space. Specifically, the expression print(*my_tuple, sep=', ') will print the tuple elements without parentheses and with a comma between subsequent tuple elements.

my_tuple = (1, 2, 3)
print(*my_tuple, sep=', ')
# Output: 1, 2, 3

Method 3: Slicing String Representation

Slicing is a concise way to access a subsequence from an original sequence. You can use slicing on the string representation of a tuple to access all characters except the first and last ones—that are the opening and closing parenthesis characters. For example, the expression print(str((1, 2, 3))[1:-1]) prints the tuple as "1, 2, 3" without enclosing parentheses.

my_tuple = (1, 2, 3)
print(str(my_tuple)[1:-1])
# Output: 1, 2, 3

Method 4: String Join With Generator Expression

You can print a tuple without parentheses by combining the string.join() method on the separator string ', ' with a generator expression to convert each tuple element to a string using the str() built-in function. Specifially, the expression print(', '.join(str(x) for x in my_tuple)) prints my_tuple to the shell without enclosing parentheses.

my_tuple = (1, 2, 3)
print(', '.join(str(x) for x in my_tuple))
# Output: 1, 2, 3

You can modify the separator string on which you join to customize the appearance of the tuple:

my_tuple = (1, 2, 3)
print('-'.join(str(x) for x in my_tuple))
# Output: 1-2-3

Where to Go From Here?

Enough theory. Let’s get some practice!

Coders get paid six figures and more because they can solve problems more effectively using machine intelligence and automation. To become more successful in coding, solve more real problems for real people. That’s how you polish the skills you really need in practice. After all, what’s the use of learning theory that nobody ever needs?

You build high-value coding skills by working on practical coding projects!

Do you want to stop learning with toy projects and focus on practical code projects that earn you money and solve real problems for people?

If your answer is YES!, consider becoming a Python freelance developer! It’s the best way of approaching the task of improving your Python skills—even if you are a complete beginner.
