Given a list of elements. If you print the list to the shell using
print([1, 2, 3]), the output is enclosed in square brackets 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 list without enclosing brackets?
Method 1: Unpacking
The asterisk operator
* is used to unpack an iterable into the argument list of a given function. You can unpack all list 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_list) will print the elements in
my_list, empty-space separated, without the enclosing square brackets!
my_list = [1, 2, 3] print(*my_list) # Output: 1 2 3

Method 2: Unpacking with Separator
To print a comma-separated list without enclosing square brackets, the most Pythonic way is to unpack all list values into the
print() function and use the
sep=', ' argument to separate the list elements with a comma and a space. Specifically, the expression
print(*my_list, sep=', ') will print the list elements without brackets and with a comma between subsequent list elements.
my_list = [1, 2, 3] print(*my_list, sep=', ') # Output: 1, 2, 3

print() function in the following video:
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 list to access all characters except the first and last ones—that are the square bracket characters. For example, the expression
print(str([1, 2, 3])[1:-1]) prints the list as
"1, 2, 3" without enclosing square brackets.
my_list = [1, 2, 3] print(str(my_list)[1:-1]) # Output: 1, 2, 3

Method 4: String Join With Generator Expression
You can print a list without brackets by combining the
string.join() method on the separator string
', ' with a generator expression to convert each list element to a string using the
str() built-in function. Specifially, the expression
print(', '.join(str(x) for x in my_list)) prints
my_list to the shell without enclosing brackets.
my_list = [1, 2, 3] print(', '.join(str(x) for x in my_list)) # Output: 1, 2, 3
You can modify the separator string on which you join to customize the appearance of the list:
my_list = [1, 2, 3] print(' '.join(str(x) for x in my_list)) # Output: 1 2 3
string.join(iterable)method concatenates the elements in the given iterable.
str(object)built-in function converts a given object to its string representation.
- Generator expressions or list comprehensions are concise one-liner ways to create a new iterable based by reusing elements from another iterable.
