There are different ways through which we can print to the console without a newline. Let’s quickly go through some of these methods.<\/p>\n\n\n\n

\n\n\n\n

1. Using print()<\/h2>\n\n\n\n

We can use the print()<\/code> function to achieve this, by setting the end<\/code> (ending character) keyword argument appropriately.<\/p>\n\n\n\n

By default, this is a newline character (\\n<\/code>). So, we must change this to avoid printing a newline at the end.<\/p>\n\n\n\n

There are many options for this choice. We could use a space to print space-separated strings.<\/p>\n\n\n

\na = "Hello"\nb = "from AskPython"\n\nprint(a, end=' ')\nprint(b)\n<\/pre><\/div>\n\n\n
This would print strings a<\/code> and b<\/code>, separated by a single space, instead of a newline.<\/p>\n\n\n\n
Output<\/strong><\/p>\n\n\n
\nHello from AskPython\n<\/pre><\/div>\n\n\n
We could also print them consecutively, without any gap, by using an empty string.<\/p>\n\n\n
\na = "Hello"\nb = "from AskPython"\n\nprint(a, end='')\nprint(b)\n<\/pre><\/div>\n\n\n
Output<\/strong><\/p>\n\n\n
\nHellofrom AskPython\n<\/pre><\/div>\n\n\n
\n\n\n\n
2. Printing list elements without a Newline<\/h2>\n\n\n\n
Sometimes, when iterating through a list, we may need to print all its elements on the same line. To do that, we can again use the same logic as before, using the end<\/code> keyword argument.<\/p>\n\n\n
\na = ["Hello", "how", "are", "you?"]\n\nfor i in a:\n    print(i, end=" ")\n<\/pre><\/div>\n\n\n
Output<\/p>\n\n\n
\nHello how are you?\n<\/pre><\/div>\n\n\n
\n\n\n\n
3. Using the sys module<\/h2>\n\n\n\n
We can also use the sys<\/code> module<\/a> to print without a newline.<\/p>\n\n\n\n
More specifically, the sys.stdout.write()<\/code> function enables us to write to the console without a newline.<\/p>\n\n\n
\nimport sys\nsys.stdout.write("Hello from AskPython.")\nsys.stdout.write("This is printed on the same line too!")\n<\/pre><\/div>\n\n\n
Output<\/strong><\/p>\n\n\n
\nHello from AskPython.This is printed on the same line too!\n<\/pre><\/div>\n\n\n
\n\n\n\n
4. Creating our own C style printf() function<\/h2>\n\n\n\n
We can also create our custom printf()<\/code> function in Python! Yes, this is possible using the module functools<\/code>, which allows us to define new functions from existing ones via functools.partial()<\/code>!<\/p>\n\n\n\n
Let’s use the same logic on the end<\/code> keyword argument on print()<\/code> and use it to create our printf()<\/code> function!<\/p>\n\n\n
\nimport functools\n\n# Create our printf function using\n# print() invoked using the end=""\n# keyword argument\nprintf = functools.partial(print, end="")\n\n# Notice the semicolon too! This is very familiar for a\n# lot of you!\nprintf("Hello!");\nprintf("This is also on the same line!");\n<\/pre><\/div>\n\n\n
Output<\/strong><\/p>\n\n\n
\nHello!This is also on the same line!\n<\/pre><\/div>\n\n\n
We can also combine the semicolon to this (Python compiler will not complain) to bring back our C printf()<\/code> function as it was! <\/p>\n\n\n\n
