python string template example

in python, the string module provides a flexible template class for string manipulation called template. this module allows you to create string templates with placeholders, making it easy to substitute values into the template. in this tutorial, we'll explore the basics of using the template class with code examples.
the template class uses a dollar sign ($) followed by an identifier as a placeholder in the template string. to substitute values into the template, you use the substitute method.
output:
if your template string contains a literal dollar sign, you need to escape it by using two dollar signs ($$).
output:
if a placeholder in the template is not provided with a value during substitution, a keyerror is raised. to handle this situation gracefully, you can use the safe_substitute method.
output:
you can also use dictionaries or keyword arguments for substitution.
output:
the template class in the string module provides a simple and powerful way to create string templates in python, making it easy to substitute values and customize strings dynamically.
