In Python, a string is text: an object of type str that stores a sequence of Unicode characters—names, messages, file paths, and almost every piece of text a program prints or reads.
You create strings with single quotes, double quotes, or triple quotes for multi-line text. Build messages with f-strings (f"Hi, {name}") or +. Strings are immutable: methods return a new string; they never change the original.
This page teaches what a Python string is. The String Methods index lists every method guide (capitalize(), find(), format(), and more).
Write text = text.upper(). Calling text.upper() alone does not update text.
For everyday messages in Python 3.6+, f"..." is clearer than chaining + or older % formatting.
Common ways to create and inspect strings:
literal = "Hello, Python!" # double or single quotes
name = "Ada"
hello = f"Hi, {name}!" # f-string
full = first + " " + last # + concatenation
length = len(text) # number of characters
ch = text[0] # first character (zero-based)
found = text.find("Py") # search (method)Ideas every Python string tutorial builds on:
| Idea | Example | Remember |
|---|---|---|
| Literal | "Hello" or 'Hello' | Single and double quotes are equivalent |
| f-string | f"Hi, {name}" | Embed expressions in braces |
| Concatenation | a + " " + b | Creates a new string |
| Length | len(s) | Built-in function, not a method |
| Indexing | s[0], s[-1] | Zero-based; negatives count from the end |
| Immutability | s.upper() | Returns a new string |
Five short programs that define how strings work in a Python tutorial.
Assign text and display it with print.
language = "Python"
version = 3
print("Language:", language)
print("Version:", version)
print("Ready to learn strings!")Quotes inside strings and multi-line text.
quote = 'She said, "Hello!"'
path = "C:\\Users\\Dev\\project"
lines = """Line 1
Line 2"""
print(quote)
print(path)
print(lines)Build messages the modern Python way.
first = "Hello"
last = "Python"
score = 95
greeting = first + ", " + last + "!"
print(greeting)
print(f"{first}, {last}!")
print(f"Score: {score}"){ }.Measure length and read characters by position.
word = "Hello"
print("length:", len(word))
print("first:", word[0])
print("last:", word[-1])
print("slice:", word[1:4])Everyday method calls you will open next on the methods index.
url = "https://codetofun.com/python/string"
file = "main.py"
print(url.find("/python"))
print(file.endswith(".py"))
print("Checked {0} chars".format(len(url)))-1 if missing).{0} placeholders (f-strings are often clearer).After you know what a string is, open the method index for full tutorials on every essential str method in this Python series.
| Start with | Why |
|---|---|
capitalize() | First character upper, rest lower |
find() | Search for a substring |
format() | Fill template placeholders |
isdigit() | Validate digit-only text |
