1. Dictionary Intersection using ‘&’ Operator The simplest method to find the intersection of keys, values or items is to use&(ampersand) operator between two dictionaries. This operator creates a new dictionary containing only the key-value pairs that are common to both dictionaries. In the ...
Pandas Seriesis a one-dimensional array that is capable of storing various data types (integer, string, float, python objects, etc.). We can easily convert the list, tuple, and dictionary into Series using thepandas.Series()function. The row labels of the Series are called theindex. The S...
Tuples in Python are common types of collections that are used commonly for storing data records in python for processing. In fields like data science and AI, we need to process data tuples to extract fruitful information. In this problem, we will create a python program to perform tuple i...

Write a Python program that performs common set operations like union, intersection, and difference of two frozensets. Sample Solution: Code: defmain():frozenset_x=frozenset([1,2,3,4,5])frozenset_y=frozenset([0,1,3,7,8,10])print("Original frozensets:")print(frozenset_x)print(...
2. Frequency dictionary: class Solution: def intersect(self, nums1: List[int], nums2: List[int]) -> List[int]: dict = {} ans = [] # Building the frequency dict for nums1 for i in nums1: if i in dict.keys(): dict[i] += 1 else: dict[i] = 1 # Search in the freqency...
The study of plant photosynthesis is essential for productivity and yield. Thanks to the development of high-throughput phenotyping (HTP) facilities, based on chlorophyll fluorescence imaging, photosynthetic traits can be measured in a reliable, reproduc
