Strings
Explore how to create, manipulate, and format strings using Python’s built-in syntax and string methods.
Strings
Strings are one of the most commonly used data types in Python.
Creating Strings
pythonCopyEditname = "Alice" greeting = 'Hello'
Python supports both single (') and double (") quotes.
Multiline Strings
Use triple quotes for multiline strings:
pythonCopyEditmessage = """This is a multi-line string."""
String Concatenation
pythonCopyEditfirst = "Hello" second = "World" combined = first + " " + second print(combined) # Output: Hello World
String Interpolation
Use f-strings (Python 3.6+):
pythonCopyEditname = "Alice" print(f"Hello, {name}!")
Common String Methods
pythonCopyEdittext = "Python is fun" text.upper() # 'PYTHON IS FUN' text.lower() # 'python is fun' text.startswith("Py") # True text.replace("fun", "awesome") # 'Python is awesome'
String Slicing
pythonCopyEditword = "Python" print(word[0:3]) # 'Pyt' print(word[-1]) # 'n'
Strings are immutable, meaning their content cannot be changed in place.
