Python Print Without New Lines

In Python, the built-in print() function is commonly used to display output on the console. By default, it appends a new line character (\n) after each call. However, there are situations where you might want to print without a new line.

Using the end parameter of the print() function

The print() function in Python has an optional end parameter that determines what character(s) are used to separate consecutive calls. By default, end='\n', which adds a new line after each print statement. To print without new lines, you can change the end parameter to an empty string:

print("Hello", end='')
print("World", end='')
print("!", end='')

Output:

HelloWorld!

As seen in the above example, the print statements are concatenated without new lines because the end parameter is set to an empty string.

Using the sep parameter of the print() function

Apart from the end parameter, the print() function also has a sep parameter. It specifies the separator between multiple objects printed by one print() statement. By default, sep=' ' adds a space character between objects. To print without new lines, you can set sep to an empty string:

print("Hello", "World", "!", sep='')

Output:

HelloWorld!

By setting sep to an empty string, the objects are concatenated without any separator, resulting in a single string without new lines.

Using the sys.stdout.write() function

Another way to print without new lines is to use the sys.stdout.write() function. This function writes a string to the standard output without appending a new line:

import sys

sys.stdout.write("Hello")
sys.stdout.write("World")
sys.stdout.write("!")

Output:

HelloWorld!

Note that the sys.stdout.write() function does not automatically add a new line, so you need to manually include spaces or new lines if needed.

Conclusion

In this guide, we explored various methods to print without new lines in Python. You can achieve this by modifying the end parameter of the print() function to an empty string, setting the sep parameter to an empty string, or using the sys.stdout.write() function. Choose the method that best suits your requirements and coding style.
