F-strings and string splicing are both methods for creating formatted strings in Python. However, they have distinct approaches and use cases:

1. F-Strings (formatted string literals):

• Introduced in Python 3.6, f-strings are a powerful and concise way to embed expressions directly within strings.
• They use an f prefix before the opening quotation mark.
• Here's the basic syntax:

f"Hello, my name is {name} and I am {age} years old."

• In this example, name and age are variables. The curly braces {} around them indicate that their values will be inserted at those positions in the string.
• F-strings can also include more complex expressions and formatting options:

radius = 5.2
formatted_area = f"The area of the circle is approximately {3.14 * radius**2:.2f} square units."

Advantages of F-strings:

• Readability: The code is more readable as the formatting and variables are integrated within the string.
• Flexibility: You can include complex expressions and formatting options within the curly braces.
• Conciseness: F-strings eliminate the need for separate string manipulation steps.

2. String Splicing:

• String splicing involves creating a new string by combining smaller string literals and variables using the + operator.
• Here's an example:

name = "Alice"
age = 30
greeting = "Hello, " + name + "! You are " + str(age) + " years old."

• In this case, we use string concatenation (+) to join the string literals and convert the age variable (an integer) to a string using str().

Advantages of String Splicing:

• Simpler for basic formatting: For very basic string concatenation, splicing might be slightly simpler to read.

When to Use Each Method:

• Generally, f-strings are preferred due to their readability, flexibility, and avoidance of extra string conversions.
• Use string splicing for situations where f-strings might be less readable, such as when concatenating multiple strings with no variable insertion:

file_path = "data/" + filename
