collectionsis a Python standard library, and it contains theCounterclass to count the hashable objects. Counterclass has two methods : keys()returns the unique values in the list. values()returns the count of e
Approach:Convert the given list into a set using theset()function. Since a set cannot contain duplicate values, only the unique values from the list will be stored within the set. Now that you have all the unique values at your disposal, you can simply count the number of unique values ...
When you convertmy_listto a set, Python eliminates all duplicate entries. The resulting set,unique_values, contains only the unique elements from the original list. Keep in mind that sets are unordered, so the output might not reflect the original order of elements. If order matters, you mig...

Method 4 – Use the LOOKUP and COUNTIF Formula to Get Unique Values From a Range Steps: Select cellE5. Insert the following formula in it: =LOOKUP(2,1/(COUNTIF($E$4:E4,$B$5:$B$20)=0),$B$5:$B$20) Formula Explanation
You never know who might show up to help out. Real Python hosted open spaces at PyCon in 2019 and 2022. They were great events with existing members and people who didn’t know us very well. We won’t be hosting an open space this year, but you should definitely check out some of...
Use a different hashing algorithm: The crc32 function may not be suitable for generating unique hash values. You can try using a different hashing algorithm such as SHA-256 or MD5. These algorithms are designed to generate unique hash values for different inputs. UUID3 and UUID5 in Pyth...
