Final answer:
In Python, %r is used for a deb_ugger-friendly representation of an object using repr(), whereas %s provides a human-readable description using str().
Step-by-step explanation:
The difference between %r and %s is found within the Python programming language, specifically when using the string formatting operations. The %s specifier converts any Python object using str(), which means it provides a human-readable representation of the object, ideal for displaying output to users. Conversely, the %r specifier converts the object using repr(), which generates a representation that can be read by the interpreter or would be useful for debugging. This generally means the output of %r can include escape characters and any other symbols that are part of the object's representation.
Here is an example to illustrate the difference:
print("Human-readable format: %s" % 'Hello\\World')
print("Interpreter-readable format: %r" % 'Hello\\World')
The output would be:
Human-readable format: Hello
World
Interpreter-readable format: 'Hello\\World'
