Python Strings

Python Strings

Strings in Python are arrays of bytes representing Unicode characters. However, Python does not have a character data type, a single character is simply a string with a length of 1.

Creating Strings

Strings can be created by enclosing characters inside single quotes, double quotes, or triple quotes:

# Single quotes
x = 'Hello'

# Double quotes
y = "World"

# Triple quotes for multiline
z = """This is a
multiline string"""

String Operations

You can use the + operator to concatenate strings:

a = "Hello"
b = "World"
c = a + " " + b
print(c)  # Hello World

String Methods

Python has a set of built-in methods that you can use on strings:

# Upper case
txt = "Hello World"
print(txt.upper())  # HELLO WORLD

# Lower case
print(txt.lower())  # hello world

# Strip whitespace
txt = " Hello World "
print(txt.strip())  # "Hello World"

# Replace string
print(txt.replace("H", "J"))  # Jello World

# Split string
print(txt.split())  # ['Hello', 'World']

String Formatting

Python uses format() method to format strings:

age = 36
txt = "My name is John, and I am {}"
print(txt.format(age))  # My name is John, and I am 36
