What are string formatting options?

In Python, string formatting options allow you to create formatted strings by embedding values within a string. Here are some common methods for string formatting:

1. f-strings (formatted string literals) (Python 3.6+):

   name = "Alice"
   age = 30
   formatted_string = f"My name is {name} and I am {age} years old."

2. str.format() method:

   name = "Alice"
   age = 30
   formatted_string = "My name is {} and I am {} years old.".format(name, age)

3. Percent formatting (older style):

   name = "Alice"
   age = 30
   formatted_string = "My name is %s and I am %d years old." % (name, age)

4. Using format specifiers:
   You can control the width, precision, and alignment of the output using format specifiers:

   value = 123.456
   formatted_string = "Value: {:.2f}".format(value)  # Output: Value: 123.46

5. Using str.format() with named placeholders:

   formatted_string = "My name is {name} and I am {age} years old.".format(name="Alice", age=30)

6. Padding and alignment:
   You can specify padding and alignment:

   formatted_string = "{:<10} | {:>10}".format("Left", "Right")  # Left-aligned and right-aligned

These methods provide flexibility in formatting strings to meet various output requirements.
