There is no point in adding unused strings to the code. If the first line of a function or a class is a string, it's considered documentation, but otherwise short strings (enclosed in single quotes ``'`` or double quotes ``"``) that aren't either assigned to variables or used in function calls or expressions are considered confusing cruft, and should be removed.


== Noncompliant Code Example

----
def fun():
    'documentation string'    # Compliant
    print('Hello, world')
    'Hello, world'    # Noncompliant; has no effect
    ''' Long strings are ignored '''   # Compliant
----


== Compliant Solution

----
def fun():
    'documentation string'    # Compliant
    print('Hello, world')
    ''' Long strings are ignored '''   # Compliant
