How to Print on the Same Line in Python

Printing output on the same line is a common formatting requirement in Python.

This guide explores various techniques to achieve this, focusing on the print() function, iterable unpacking, str.join(), and combining printing with input on the same line.

Printing on the Same Line with end Argument​

The print() function's end argument controls what's printed at the end of the output, defaulting to a newline character (\n). Setting it to a space (' ') prints items on the same line, separated by spaces.

my_list = ['tutorial', 'reference', 'com']

for item in my_list:
    print(item, end=' ')  # Output: tutorial reference com
note

This method is useful when iterating over an iterable and printing its elements horizontally.

Printing with Iterable Unpacking​

The iterable unpacking operator (*) unpacks an iterable's items as arguments to a function. This provides a concise way to print items on the same line, separated by spaces:

my_list = ['tutorial', 'reference', 'com']
print(*my_list)  # Output: tutorial reference com
  • The * operator unpacks the items in my_list as separate arguments to print().
note

You can control the separator with the sep argument:

my_list = ['tutorial', 'reference', 'com']
print(*my_list, sep='')     # Output: tutorialreferencecom
print(*my_list, sep='-')    # Output: tutorial-reference-com

Printing with str.join()​

The str.join() method efficiently concatenates a list of strings into a single string, allowing you to print them on the same line with a separator.

my_list = ['tutorial', 'reference', 'com']
result = ' '.join(my_list)
print(result) # Output: tutorial reference com

The str.join() method is called on the desired separator string (' ' for a space), and its argument is the list of strings to join.

To print numbers horizontally, convert them to strings:

my_list = [2, 4, 8]
result = ' '.join(str(number) for number in my_list)
print(result) # Output: 2 4 8

Combining print() and input() on the Same Line​

To print a message and take user input on the same line, pass the prompt directly to the input() function:

username = input('Enter your username: ')
print(username) # Prints on a new line

If you want to keep both the print() and input() on the same line, you can pass a prompt argument to the input function, and print the result on the same line using the sep and end arguments:

print(
    'Your username is: ',
    input('Enter your username: '),
    sep='',
    end=''
)

Alternatively, you can achieve the same using an f-string.

print(f'Your name is: {input("Enter your name: ")}')
