Print a list without the commas and brackets in Python #

To print a list without the commas and brackets:

  1. Use the str.join() method to join the list into a string.
  2. If the list contains numbers, convert them to strings.
  3. Use the print() function to print the string.
main.py
list_of_strings = ['bobby', 'hadz', '.com'] # ✅ Print list of strings without commas, brackets and quotes result = ''.join(list_of_strings) print(result) # 👉️ bobbyhadz.com # --------------------------------------------- # ✅ Print list of integers without commas, brackets and quotes list_of_integers = [7, 21, 44] result = ''.join(str(item) for item in list_of_integers) print(result) # 👉️ 72144

We used the str.join() method to print a list without the commas, brackets and quotes.

The str.join method takes an iterable as an argument and returns a string which is the concatenation of the strings in the iterable.

Note that the method raises a TypeError if there are any non-string values in the iterable.

If your list contains numbers or other types, convert all of the values to strings before calling join().

main.py
list_of_integers = [7, 21, 44] result = ''.join(str(item) for item in list_of_integers) print(result) # 👉️ 72144

We used a generator expression to iterate over the list.

Generator expressions are used to perform some operation for every element or select a subset of elements that meet a condition.

On each iteration, we use the str() class to convert the number to a string.

The string the join() method is called on is used as the separator between the elements.

main.py
list_of_strings = ['bobby', 'hadz', '.com'] result = ' '.join(list_of_strings) print(result) # 👉️ bobby hadz .com # --------------------------------------------- list_of_integers = [7, 21, 44] result = ' '.join(str(item) for item in list_of_integers) print(result) # 👉️ 7 21 44

If you don't need a separator and just want to join the list's elements into a string, call the join() method on an empty string.

You can also use the map() function to convert all items in the list to strings before calling join().

main.py
list_of_integers = [7, 21, 44] result = ''.join(map(str, list_of_integers)) print(result) # 👉️ 72144

The map() function takes a function and an iterable as arguments and calls the function with each item of the iterable.

Alternatively, you can use the sep argument in the call to the print() function.

Print a list without the commas and brackets using sep #

Use the sep argument to print a list without the commas and brackets, e.g. print(*my_list, sep=''). The items in the list will get unpacked in the call to the print() function and will get printed without commas, brackets and quotes.

main.py
list_of_strings = ['bobby', 'hadz', '.com'] print(*list_of_strings, sep='') # 👉️ bobbyhadz.com # --------------------------------------------- list_of_integers = [7, 21, 44] print(*list_of_integers, sep='') # 👉️ 72144
Notice that we used the iterable unpacking * operator to unpack the items of the list in the call to print().

The * iterable unpacking operator enables us to unpack an iterable in function calls, in comprehensions and in generator expressions.

The sep argument is the separator between the arguments we pass to print().

main.py
list_of_strings = ['bobby', 'hadz', '.com'] print(*list_of_strings, sep='') # 👉️ bobbyhadz.com print(*list_of_strings, sep=' ') # 👉️ bobby hadz .com print(*list_of_strings, sep='-') # 👉️ bobby-hadz-.com

By default, the sep argument is set to a space.
