               ):
    s = list(s
                )
    s.sort()
 
 
    for i in range(len(s) - 1):
        if s[i] == s[i + 1]:
            return 0

# Example formatted using Black

def is_unique(s):
    s = list(s)
    s.sort()

    for i in range(len(s) - 1):
        if s[i] == s[i + 1]:
            return 0
    else:
        return 1

Using Databricks built-in Black support allows the developer to adopt to the PEP8 standard. Keeping your code well-fromatted, clean and readable.

To quote Black’s README:

Black is the uncompromising Python code formatter. By using it, you agree to cede control over minutiae of hand-formatting. In return, Black gives you speed, determinism, and freedom from pycodestyle nagging about formatting. You will save time and mental energy for more important matters.
