Python also allows more complex formatting of output using f-strings (formatted string literals), str.format(), or the older % operator.

Example 1: Using f-Strings (Python 3.6+)

name = "Harsha"
age = 30
print(f"My name is {name} and I am {age} years old.")

Output:

My name is Harsha and I am 30 years old.

F-strings allow you to embed expressions inside string literals by prefixing the string with f.

Example 2: Using str.format()

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

Output:

My name is Harsha and I am 30 years old.

str.format() is an older method for formatting strings by substituting placeholders ({}) with variable values.

Example 3: Using the % Operator

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

Output:

My name is Harsha and I am 30 years old.

This method is based on C-style string formatting, where %s is used for strings, %d for integers, etc. This approach is considered outdated compared to f-strings and str.format().
