Print Statement

What Is the print() Statement?

🔹 Simple Meaning

The print() function is used to:

display output to the screen.

It is usually the first Python function beginners learn.

Example:

print("Hello, world!")

Output:

Hello, world!

So:

👉 print() = show something on the screen

Why print() Is Important

We use print() to:

• see results of our code
• test if our program works
• display messages to users
• debug (find errors)

Basic Syntax

print(value)

You can print:

• text
• numbers
• variables
• results of calculations

Printing Different Data Types

print("Python")   # string
print(10)         # integer
print(3.5)        # float

Printing Variables

name = "Ada"
print(name)

Output:

Ada

Printing Multiple Items

print("My name is", "Ada")

Output:

My name is Ada

Python automatically adds a space between them.

Important Parameters of print()

| Parameter | Meaning (Simple)                              | Example                          |
|-----------|-----------------------------------------------|----------------------------------|
| sep       | Separates multiple values                     | print("A","B", sep="-")          |
| end       | What is printed at the end                    | print("Hello", end="!")          |
| file      | Sends output to a file                        | print("Hi", file=f)              |

The sep Parameter

Default separator is a space.

Example:

print("2026", "02", "23", sep="-")

Output:

2026-02-23

The end Parameter

By default, print() ends with a new line.

Example:

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

Output:

Hello World

Printing Calculations

print(5 + 3)

Output:

8

Formatting Output

This is the modern and best way.

name = "Ada"
age = 20

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

Different Ways to Format Strings

| Method        | Example                                  | Recommended? |
|---------------|--------------------------------------------|--------------|
| Comma         | print("Age:", age)                         | ✅ Good       |
| f-string      | print(f"Age: {age}")                       | ⭐ Best       |
| format()      | print("Age: {}".format(age))               | 👍 Good       |
| % formatting  | print("Age: %d" % age)                     | ❌ Old style  |

Printing Quotes

If your text contains quotes:

print("She said 'Hello'")

OR

print('She said "Hello"')

Printing on Multiple Lines

print("Line 1")
print("Line 2")

OR

print("""Line 1
Line 2
Line 3""")

Using print() for Debugging

You can check what is happening in your code:

x = 5
print(x)

This helps you:

• track values
• find errors

Common Beginner Mistakes

| Mistake                         | Why It Happens                     | Fix                                  |
|----------------------------------|------------------------------------|---------------------------------------|
| Missing quotes                   | Python thinks it’s a variable      | print("Hello")                        |
| Wrong case (Print)               | Python is case-sensitive           | print() not Print()                   |
| Missing parentheses              | Using Python 3                     | print()                               |
| Space in variable name           | Invalid syntax                     | use underscore                        |

print() in Python 2 vs Python 3

| Python 2        | Python 3        |
|-----------------|-----------------|
| print "Hello"   | print("Hello")  |

Python 3 uses parentheses ✅

Real-Life Uses of print()

| Use Case              | Example                                  |
|------------------------|------------------------------------------|
| Showing results        | Display total price                      |
| User messages          | Welcome screen                           |
| Debugging              | Checking variable values                 |
| Learning Python        | Understanding program flow               |

Final Summary

In one sentence:

print() is used to display output to the screen in Python.

The most important things to remember:

✔ It shows results

✔ It can print text, numbers, and variables

✔ It supports formatting (f-strings are best)

✔ It helps in debugging

Most Important Example for Beginners

name = "Danny"
age = 25

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