Python Program to Print Output Without a Newline

The provided Python code demonstrates how to print output without a newline character using the print() function. By specifying the end parameter with an empty string (''), the function ensures that the default newline character at the end of the printed text is replaced with nothing. In the example, the string “Hello,” is printed first with no newline character appended to it. Then, “world!” is printed, and since there is no newline character at the end of “Hello,” and “world!” is printed, it appears immediately after “Hello,” on the same line. As a result, the output displays both strings consecutively without any newline separation between them. This technique is useful when you want to control the formatting of output, particularly when you want to concatenate multiple strings together on the same line.

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

Description

Here’s a step-by-step breakdown of the provided Python code:

1. Importantly, the code utilizes the print() function, which is used to display output in Python.
2. Within the print() function, there is a string "Hello,", which represents the text that will be printed to the screen.
3. Additionally, there is the end parameter specified within the print() function. This parameter is used to determine what character or string will be printed at the end of the output. In this case, it’s set to an empty string '', indicating that nothing should be printed after the text.
4. The first print() statement executes, displaying the string "Hello," on the screen without any newline character appended to it, as instructed by the end='' parameter.
5. Following the first print() statement, there is another print() statement, which displays the string "world!".
6. Since there is no newline character at the end of the "Hello," string and the end parameter for the first print() statement was set to an empty string, the "world!" string is printed immediately after "Hello," on the same line.
7. The combined effect is that both strings, "Hello," and "world!", are displayed consecutively without any newline separation between them.

Overall, this approach allows for the precise control of output formatting, enabling strings to be concatenated and displayed on the same line when desired.
