Python Strings

Creating Strings with Quotes

You can create a string using single quotes or double quotes — Python treats them the same way. Use whichever is convenient, especially when your text itself contains one type of quote.

greeting = 'Hello there'
name = "Aisha's friend"
print(greeting, name)

String Indexing

Each character in a string has a position, called an index, starting from 0. You can access a single character using square brackets, and negative indexes count backward from the end.

word = "Python"
print(word[0])   # P
print(word[5])   # n
print(word[-1])  # n (last character)
print(word[0:3]) # Pyt (slicing)

String Concatenation

You can join, or "concatenate", strings together using the + operator. Remember that + only works between strings, so numbers must be converted first.

first = "Learn"
second = "Python"
combined = first + " " + second
print(combined)

f-strings — Formatted Strings

f-strings are the modern, preferred way to build strings that include variable values. Add an f before the opening quote, then place variables directly inside curly braces.

name = "Sanya"
age = 23
message = f"{name} is {age} years old"
print(message)

Multiline Strings

Wrap text in triple quotes to create a string that spans multiple lines, which is useful for paragraphs or docstrings.

bio = """Hi, I'm learning Python.
It is my first programming language.
I'm excited to build real projects!"""
print(bio)
