Formatting in Python

Formatting strings in python is very convenient, mostly because most types have a __str__ method that returns a string representation of the object. Because of this, we can format most types seamlessly.

The most common way to format strings in Python is by using the format method. This method allows you to insert values into a string by using placeholders and passing the values as arguments to the format method.

By using the format method, you can insert values into a string in a specific order defined by the placeholders {}.

name = "Alice"
age = 30

message = "Hello, my name is {} and I am {} years old.".format(name, age)
print(message) # Output: Hello, my name is Alice and I am 30 years old.

From python 3.6 onwards, you can also use f-strings to format strings. F-strings Let you embed expressions inside string literals, using curly braces {}.

name = "Alice"
age = 30

message = f"Hello, my name is {name} and I am {age} years old."
print(message) # Output: Hello, my name is Alice and I am 30 years old.
