Python's String Formatting Operator %

Question: What is the function of the % operator when applied to strings in Python?

Answer: The % operator is used for string formatting in Python. It allows you to create formatted strings by inserting values into a specified format.

The basic syntax is:

format % values

The format specifier string (format) contains placeholders (%s, %d, etc.), and the values tuple (values) contains the values to be inserted into these placeholders.

For example:

<code class="python">name = "John"
age = 30

formatted_string = "Hi, I'm %s and I'm %d years old." % (name, age)
print(formatted_string)</code>

Output:

Hi, I'm John and I'm 30 years old.

In this example, the %s placeholder is replaced with the value of the name variable, and the %d placeholder is replaced with the value of the age variable.
