Remove Str From Fstring¶

Sourcery refactoring id: `remove-str-from-fstring`¶

Description¶

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

Before¶

def description(name: str, age: int):
    return f"Name: {str(name)}, Age: {str(age)}"

After¶

def description(name: str, age: int):
    return f"Name: {name}, Age: {age}"

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.
