Print Single and Multiple variable in Python

In Python, printing single and multiple variables refers to displaying the values stored in one or more variables using the print() function.

Let's look at ways how we can print variables in Python:

Printing a Single Variable in Python

The simplest form of output is displaying the value of a single variable using the print() function.

Example:

x = 42

print(x)

42

Explanation: x stores the value 42, and print(x) displays it on the console.

Printing Multiple Variables

Python allows printing multiple variables in various ways. Let’s explore three common techniques:

1. Using Commas (default way)

a = 10
b = 20
c = 30

print(a, b, c)

10 20 30

Explanation: When variables are separated by commas, Python prints them with a space between each.

2. Using f-strings (formatted string literals)

name = "Prajjwal"
age = 23

print(f"My name is {name} and I am {age} years old.")

My name is Prajjwal and I am 23 years old.

Explanation:

• f-strings are prefixed with the letter f before the opening quote.
• Inside the string, curly braces {} act as placeholders for variables or expressions.
• Python automatically replaces each {} with the value of the corresponding variable.

Note: f-strings is compatible with latest Python versions (Python 3.6+).

3. Using .format() Method

lang = "Python"
ver = 3

print("You are learning {} version {}.".format(lang, ver))

You are learning Python version 3.

Explanation:

• In the string, the curly braces {} act as placeholders.
• .format() method replaces the {} in the string in order with the values passed to it.

Note: .format() is compatible with older Python versions and still widely used in legacy code.
