print() in Python

The print() function in Python is used to output messages to the screen or any other standard output device.

Syntax:​

print(value(s), sep=' ', end='\n', file=file, flush=flush)

Parameters:​

• value(s): Any value(s) you wish to print. These values will be converted to a string before being printed.
• sep: (Optional) Specifies the separator between multiple values. Default is a space ' '.
• end: (Optional) Specifies what to print at the end. Default is a newline '\n'.
• file: (Optional) An object with a write method. Default is sys.stdout.
• flush: (Optional) A boolean indicating if the output should be flushed immediately (True) or buffered (False). Default is False.

Return Type:​

The print() function does not return a value; it outputs the specified message to the screen or other standard output.

Key Points:​

• No Arguments Required: The print() function can be called without any arguments, but it requires empty parentheses to indicate a function call.
• String Literals: Used for formatting the output.
  • \n: Adds a new line.
  • "": Prints an empty line.

Examples:​

Basic Usage:​

print("Welcome to PrepVerse")

Welcome to PrepVerse

Using \n for New Lines:​

Using end to Control End Character:​

By default, print() ends with a newline character. You can change this using the end parameter.

# Default behavior
print("Welcome to PrepVerse")
print("Learn Python")

# Custom end character
print("Welcome to PrepVerse", end=" ** ")
print("Learn Python")

Welcome to PrepVerse

Welcome to PrepVerse ** Learn Python

Using sep to Control Separator:​

When printing multiple values, the default separator is a space. You can change this using the sep parameter.

print("Python", "is", "fun", sep="-")

Python-is-fun

Conclusion​

The print() function is versatile and allows various customizations for output formatting. Understanding its parameters and how to use them effectively can significantly enhance the way you display information in Python.
