Find maximum value in each sublist in Python
We are given a list of lists (nested lists). Our task is to find the maximum value in each sublist and return them as a new list. Python provides several approaches to accomplish this efficiently. Using List Comprehension with max() The most Pythonic approach uses list comprehension combined with the max() function to iterate through each sublist ? data = [[10, 13, 454, 66, 44], [10, 8, 7, 23], [5, 15, 25]] # Given list print("The given list:") print(data) # Use max with list comprehension result = [max(sublist) for sublist in data] print("Maximum ...
Read MoreHow to set padding around an element using CSS?
The CSS padding property is used to create space between an element's content and its border. This inner spacing appears inside the element, making the content appear further from the edges. Syntax /* Individual properties */ padding-top: value; padding-right: value; padding-bottom: value; padding-left: value; /* Shorthand property */ padding: value; /* all sides */ padding: vertical horizontal; /* top/bottom left/right */ padding: top horizontal bottom; /* top left/right bottom ...
Read MoreCount tuples occurrence in list of tuples in Python
A list is made up of tuples as its elements. In this article we will count the number of unique tuples present in the list and their occurrences using different approaches. Using defaultdict We treat the given list as a defaultdict data container and count the elements in it using iteration. The defaultdict automatically initializes missing keys with a default value. Example import collections tuple_list = [('Mon', 'Wed'), ('Mon', ), ('Tue', ), ('Mon', 'Wed')] # Given list print("Given list:", tuple_list) res = collections.defaultdict(int) for elem in tuple_list: res[elem] ...
Read MoreCount the sublists containing given element in a list in Python
When working with lists in Python, you often need to count how many times a specific element appears. This article demonstrates three different approaches to count occurrences of a given element in a list. Using range() and len() This method uses a loop with range() and len() to iterate through the list indices. A counter variable tracks how many times the element is found ? days = ['Mon', 'Wed', 'Mon', 'Tue', 'Thu'] target = 'Mon' print("Given list:", days) print("Element to check:", target) count = 0 for i in range(len(days)): if ...
Read MoreDisplay div element on hovering over tag using CSS
CSS can be used to make HTML hidden components visible when hovered over. Using the adjacent sibling selector (+), we can display any HTML element when the user hovers over an tag. This selector targets an element that immediately follows another element in the DOM. Syntax a:hover + element { display: block; } How It Works The technique uses these key components − Hidden element: Initially set to display: none Adjacent sibling selector (+): Targets the element immediately after the anchor :hover pseudo-class: Triggers when mouse hovers ...
Read MoreCount the Number of matching characters in a pair of string in Python
We are given two strings and need to find the count of characters in the first string that are also present in the second string. Python provides several approaches to solve this problem efficiently. Using Set Intersection The set function gives us unique values of all elements in a string. We use the & operator to find common elements between the two strings ? Example strA = 'Tutorials Point' uniq_strA = set(strA) print("Given String:", strA) strB = 'aeio' uniq_strB = set(strB) print("Search character strings:", strB) common_chars = uniq_strA & uniq_strB print("Count of matching ...
Read MoreHow set the shadow color of div using CSS?
The CSS box-shadow property allows you to add shadow effects to any HTML element, including elements. This property creates a visual depth effect by adding shadows with customizable colors, positions, and blur effects. Syntax selector { box-shadow: h-offset v-offset blur spread color; } Property Values ValueDescription h-offsetHorizontal shadow position (positive = right, negative = left) v-offsetVertical shadow position (positive = down, negative = up) blurOptional. Blur radius − higher values create more blur spreadOptional. Spread radius − positive values expand, negative values shrink colorShadow color (hex, rgb, rgba, ...
Read MoreCount of elements matching particular condition in Python
In this article, we will see how to count elements in a Python list that match a particular condition. We'll explore different approaches to filter and count elements based on specific criteria. Using Generator Expression with sum() This approach uses a generator expression with an if condition inside the sum() function. The expression generates 1 for each element that matches the condition ? Example days = ['Mon', 'Wed', 'Mon', 'Tue', 'Thu'] # Given list print("Given list:") print(days) # Count elements that are 'Mon' or 'Wed' count = sum(1 for day in days if ...

Read MoreCount occurrences of an element in a list in Python
In this article we are given a list and a string. We are required to find how many times the given string is present as an element in the list. Python provides several methods to count occurrences, each with different advantages. Using count() Method The count() method is the most straightforward approach. It takes the element as a parameter and returns the number of times it appears in the list ? days = ['Mon', 'Wed', 'Mon', 'Tue', 'Thu'] element = 'Mon' # Given list and element print("Given list:", days) print("Given element:", element) count = ...
