Python 'end' Parameter in print()

The "end" parameter of the print() function is a useful feature in Python programming for formatting output. Many programmers find it essential. This article will explain the 'end' parameter, its syntax, and its uses.

Understanding the 'end' Parameter

By default, the print() function in Python adds a newline character at the end of each print statement, moving the cursor to the next line. The 'end' parameter allows us to change this behavior. It lets us control what character or sequence of characters follows the printed text.

Benefits of Using the 'end' Parameter

The 'end' parameter in Python offers several advantages:

Prevent Automatic Newlines: You can use 'end' to skip the automatic insertion of newlines after each print statement, ensuring your output stays on the same line.
Custom Formatting: 'end' empowers you to insert custom characters, such as spaces, commas, or newlines ('\n'), between print statements. This customization can greatly enhance the readability and aesthetics of your output.

Syntax of the 'end' Parameter

The syntax for using the 'end' parameter is simple:

print("Your text here", end="Your custom character or sequence here")

Within the double quotes of the 'end' parameter, you can specify the character(s) you want to append to your output, tailoring it to your specific needs.

Examples of 'end' Parameter Usage

Let's explore some practical examples to grasp the full spectrum of 'end' parameter utility:

1. Preventing a Space or Newline

Python Code

print("Py", end="")
print("thon")

Output

Python

2. Adding a Space and No Newline

Python Code

print("This is a tutorial on", end=" ")
print("\"end\" parameter.")

Output

This is a tutorial on "end" parameter.

3. Inserting a Comma, a Space, and No Newline

Python Code

print("Hello", end=", ")
print("Programmer")

Output

Hello, Programmer

4. Customizing Newlines

Python Code

print("Hey", end="!\n\n")
print("What's Up", end="\n")
print("Great to see you learning Python here.", end="\n\n\n\n")
print("Thank You!")

Output

Hey!

What's Up
Great to see you learning Python here.



Thank You!

5. User-Interactive Input

Python Code

print("Enter anything: ", end="")
val = input()
print("You've entered:", val)

Output

Enter anything: 10
You've entered: 10

6. Printing List Items in a Single Line

Python Code

nums = [1, 2, 3, 4, 5]
for n in nums:
    print(n, end=" ")

Output

1 2 3 4 5

The 'end' parameter is a versatile tool that allows you to take control of your Python program's output, ensuring it aligns perfectly with your specific requirements. Whether you need to format lists, create user-friendly interactive input prompts, or simply adjust the spacing between print statements, 'end' has got you covered. Happy coding!
