str’ object has no attribute ‘unique

In this article, we will see how to resolve the object that has no attribute error in Python.

This sought of error usually comes when we try to access the unique() method using the string object. the unique() method is not a standard string method in Python’s built-in string library and due to this, you can’t access the unique() method using the string objects.

To resolve this error find the place where you are trying to use the unique() using the string object and write an alternative to it.

If your intention is just to remove duplicate characters from a string, you can use this approach to convert the string into a set of characters, which automatically removes duplicates. Then, convert the set back to a string if required.

Following is an example:

my_string = "hello"
unique_chars = ''.join(set(my_string))
print(unique_chars)  

# Output: "helo"

If you just want to get the unique elements from a string, then you can use the following example program

my_string = "hello"
unique_chars = set(my_string)
print(unique_chars)  # Output: {'h', 'e', 'l', 'o'}
