String creation and representation in Python

Introduction

Strings let us store and show words or sentences in programs. They help us work with text like names, messages, or any letters.

When you want to save a person's name in your program.

When you need to display a message to the user.

When you want to store a sentence or paragraph.

When you need to keep track of any text data like addresses or emails.

Syntax

Python

string_variable = 'Hello, world!'
string_variable = "Hello, world!"
string_variable = '''This is a
multi-line string.'''
string_variable = """This is also a
multi-line string."""

You can use single quotes (' ') or double quotes (" ") to create strings.

Triple quotes (''' ''' or """ """) let you write strings that span multiple lines.

Examples

A simple string using single quotes.

Python

greeting = 'Hi there!'
print(greeting)

Using double quotes and escaping inner quotes with backslash.

Python

quote = "She said, \"Hello!\""
print(quote)

A multi-line string using triple single quotes.

Python

multi_line = '''This is line one.
This is line two.'''
print(multi_line)

A multi-line string using triple double quotes.

Python

multi_line2 = """Line one.
Line two."""
print(multi_line2)

Sample Program

This program creates strings using single quotes and triple quotes. It also shows how to insert a variable inside a string using f-strings.

Python

name = 'Alice'
welcome_message = f"Hello, {name}! Welcome to the program."
print(welcome_message)

multi_line_text = '''This program shows how strings work.
You can write text in many ways.'''
print(multi_line_text)

Important Notes

Remember to use backslash (\) to include special characters like quotes inside strings.

Strings are always inside quotes, so forgetting them causes errors.

Triple quotes are great for writing long text or notes inside your code.

Summary

Strings store text inside quotes.

Use single, double, or triple quotes depending on your needs.

Triple quotes help write multi-line text easily.
