PYTHON STRINGS

In Python, a string is a sequence of characters enclosed in quotes (either single quotes ' or double quotes "). Strings are an important data type in Python and are used to represent text-based data, such as names, addresses, and other types of information.

Here are some examples of creating strings in Python:

makefile
x = "Hello, World!" 
y = 'Hello, World!' 
z = "42"

String concatenation is the process of combining two or more strings into a single string. In Python, you can concatenate strings using the + operator. For example:

makefile
x = "Hello" 
y = "World" 
z = x + ", " + y + "!" 
print(z)  # outputs "Hello, World!"

String formatting is the process of inserting values into a string. In Python, you can format strings using the format() method. The format() method allows you to substitute placeholders with values, which can make it easier to create dynamically generated strings. For example:

python
name = "John" 
age = 30 
print("My name is {} and I am {} years old.".format(name, age))
# outputs "My name is John and I am 30 years old."

In Python, you can assign a string to a variable just like any other data type. For example:

makefile
x = "Hello, World!"

In Python, strings are immutable, which means that once a string is created, you cannot change its contents. However, you can create a new string based on an existing string. For example:

lua
x = "Hello, World!" 
y = x.upper() 
print(y)  # outputs "HELLO, WORLD!"

There are many methods available in Python for manipulating and transforming strings, such as upper(), lower(), replace(), strip(), and many others. These methods allow you to perform operations such as converting a string to uppercase or lowercase, replacing parts of a string, or removing whitespace from the beginning or end of a string.
