So, they support set operations, such as union, intersection, and difference. You can take advantage of this set-like behavior to filter certain keys from a dictionary.For example, in the code below, you use a set difference to filter out the citrus from your fruits dictionary:...

machine learning, and data engineering. He is passionate about spreading data skills and data literacy throughout organizations and the intersection of technology and society. He has an MSc in Data Science and Business Analytics. In his free time, you can find him hanging out with his cat Louis...
For this purpose, we will usenumpy.intersect1d()method which is used to find the intersection of two arrays. It returns the sorted, unique values that are in both of the input arrays. Let us understand with the help of an example, ...
There are three main approaches to coding in Python. You already used one of them, the Python interactive interpreter, also known as the read-evaluate-print loop (REPL). Even though the REPL is quite useful for trying out small pieces of code and experimenting, you can’t save your code ...
When joining several data frames, you have an option of how to handle the different axes (other than the one being concatenated). To show you how this can be used, take the union of them all,join='outer'. Consider the intersection withjoin='inner'because it causes no information loss an...
How do overloaded operators work in Python? An operator and its operands are interpreted as a cue to a corresponding function. The first operand’s Dunder method is enabled, which receives the other operands as arguments. “Dunder” stands for “double underscore”. Therefore, the plus operator...
Sets in Python are unordered collections of unique items, making them an excellent tool for comparing lists. You can perform set operations like union, intersection, and difference to compare two lists: Intersection This operation returns the common elements in two sets. seq1 = [11, 12, 13, ...
In Python, sets are built-in data structures that store an unordered collection of non-repeating and immutable elements. You can perform common operations from set theory such as union, intersection, and set difference on Python sets. This tutorial will teach you how to compute set difference in...
