In this case, we know that the duplicates are based on having the same Name, Department, and Salary values. So our output displays three rows of different ids, which tells us that there are three duplicate reco
Ideally, duplicates should always be identified before they are removed; this way, you do not mistakenly erase some useful data. Microsoft Excel offers various approaches to detect and highlight duplicate values in a given set of data. Method 1: Implementing Conditional Formatting Conditional formatti...
Add to Python Dictionary Without Overwriting Values Using the=assignment operator overwrites the values of existing keys with the new values. If you know that your program might have duplicate keys, but you don’t want to overwrite the original values, then you can conditionally add values using...

For example, you can hash the ID column using SHA-256 and then encrypt the hash value using AES-256. Check for duplicates: You can try checking for duplicates in the ID column before hashing. If there are duplicates, you can add a unique identifier to each duplicate value before ha...
The keys and values of your dictionary are string objects. You can add new pairs to the dictionary using the dict[key] = value syntax.Note: To learn more about dictionaries, check out the Dictionaries in Python tutorial.You can also create new dictionaries using the dict() constructor:...
Because the keys need to be hashable, you can’t use mutable objects as dictionary keys.On the other hand, dictionary values can be of any Python type, whether they’re hashable or not. There are literally no restrictions for values. You can use anything as a value in a Python ...
