Sourcery refactoring id: remove-str-from-fstring

Section titled “Sourcery refactoring id: remove-str-from-fstring”

Description

Section titled “Description”

Remove unnecessary calls to str() within formatted values in f-strings

Before

Section titled “Before”
def description(name: str, age: int):
    return f"Name: {str(name)}, Age: {str(age)}"

After

Section titled “After”
def description(name: str, age: int):
    return f"Name: {name}, Age: {age}"

Explanation

Section titled “Explanation”

Calls to str() are normally unnecessary within the formatted values of f-strings, since this conversion is already implicitly made. Removing them tidies up the code slightly and will yield a small performance improvement. You do need to call str() on some types with custom __repr__() methods, so this refactoring only triggers where Sourcery has inferred the type to be suitable.
