String formatting using the format() method in Python is a flexible way to insert variables into strings. Here's how it works:

Basic Syntax:
python
Copy code
"Your text here {}".format(value)
The curly braces {} act as placeholders that will be replaced by the values passed to the format() method.

Example 1: Simple Formatting
python
Copy code
name = "Martin"
age = 25
formatted_string = "My name is {} and I am {} years old.".format(name, age)
print(formatted_string)
Output:

csharp
Copy code
My name is Martin and I am 25 years old.
Example 2: Using Positional and Keyword Arguments
Positional Arguments: You can specify the order by placing numbers inside the curly braces.
Keyword Arguments: You can assign names to placeholders and pass values by keywords.
python
Copy code

Positional Arguments

formatted_string = "My name is {0} and I am {1} years old.".format("Martin", 25)
print(formatted_string)

Keyword Arguments

formatted_string = "My name is {name} and I am {age} years old.".format(name="Martin", age=25)
print(formatted_string)
Output for both:

csharp
Copy code
My name is Martin and I am 25 years old.
Example 3: Formatting Numbers
You can also format numbers (e.g., specify decimal places, align text, etc.).

python
Copy code
pi = 3.14159
formatted_pi = "The value of pi is {:.2f}".format(pi) # Rounds pi to 2 decimal places
print(formatted_pi)
Output:

csharp
Copy code
The value of pi is 3.14
Example 4: Padding and Aligning Text
You can pad text with spaces or other characters and align it (left, right, or center).

python
Copy code
formatted_string = "{:<10} | {:^10} | {:>10}".format("left", "center", "right")
print(formatted_string)
Output:

scss
Copy code
left | center | right
In this case:

< means left-align,
^ means center-align,

means right-align.

You can also use several other ways to do it, instead of using .format in the end.

For example:

name = "Martin"

age = 25

formatted_string = "My name is {} and I am {} years old.".format(name, age)

Another way:

name = "Martin"

age = 25

formatted_string = f"My name is {name} and I am {} years old."
