Python Program for Odd-Even Sort / Brick Sort
In this article, we will learn about the solution to the problem statement given below.Problem statement − We are given an array, we need to sort it using brick sort.Here we have two phases: Odd and Even Phase. In the odd phase, bubble sort is performed on odd indexed elements and in the even phase, bubble sort is performed on even indexed elements.Now let’s observe the solution in the implementation below−Exampledef oddEvenSort(arr, n): # flag isSorted = 0 while isSorted == 0: isSorted = 1 temp = 0 ...
Read MorePython Program for Merge Sort
In this article, we will learn about the solution to the problem statement given below.Problem statement − We are given an array, we need to sort it using the concept of merge sortHere we place the maximum element at the end. This is repeated until the array is sorted.Now let’s observe the solution in the implementation below −Example#merge function def merge(arr, l, m, r): n1 = m - l + 1 n2 = r- m # create arrays L = [0] * (n1) R = [0] * (n2) # Copy data to arrays ...
Read MoreHow do I disable log messages from the Requests Python module?
You can disable logging from the requests module using the logging module.ExampleYou can configure it to not log messages unless they are at least warnings using the following code:import logging logging.getLogger("requests").setLevel(logging.WARNING)If you want to go a level higher and only want to log messages when they are errors or critical, you can do replace logging.WARNING with logging.ERROR and logging.CRITICAL respectively.
Read MoreHow to extract subset of key-value pairs from Python dictionary object?
Use dictionary comprehension technique.We have dictionary object having name and percentage of students>>> marks = { 'Ravi': 45.23, 'Amar': 62.78, 'Ishan': 20.55, 'Hema': 67.20, 'Balu': 90.75 }To obtain dictionary of name and marks of students with percentage>50>>> passed = { key:value for key, value in marks.items() if value > 50 } >>> passed {'Amar': 62.78, 'Hema': 67.2, 'Balu': 90.75}To obtain subset of given names>>> names = { 'Amar', 'Hema', 'Balu' } >>> lst = { key:value for key,value in marks.items() if key in names} >>> lst {'Amar': 62.78, 'Hema': 67.2, 'Balu': 90.75}
Read MoreHow to use remote python modules?
There are ways to import Python modules remotely. It is not recommended to do so though as it will slow down your app. You can use the knockout module to achieve this. To install knockout use:$ pip install knockoutNow in order to import modules remotely, you can use knockout like:>>> from knockout import urlimport >>> urlimport.register() Url importing enabled. Add urls to sys.path.A valid url looks like this: http://example.com/path/to/repository/#packagenameThis stuff is experimental, use at your own risk. Enjoy.>>> import sys >>> sys.path.insert(0, 'http://www.crummy.com/software/BeautifulSoup/download/3.x/BeautifulSoup-3.0.8/#BeautifulSoup') >>> import BeautifulSoup ... >>> BeautifulSoup If you are not able to install modules on a machine(due ...
Read MoreLogic Gates in Python
In this article, we will learn about Logic Gates in Python. Let’s look at each of the logic gates in Python in detail with some easy examples.All of us are quite familiar while implementing logic gates in the processing of electrical signals and are widely used in the electrical and electronics industry. They are used in the diodes and transistors so that we can design by proper alignment of these electronic devices. In this article we will learn about the implementation of some basic gates ‘and‘, ‘or‘ ,’not‘ , ‘nand‘ ,’nor‘ in Python 3.x or earlier.These gates can be implemented ...
Read MoreFind average of a list in python?
Python provides sum function for calculating n number of element. Here we use this function and then calculate average. Algorithm Step 1: input “size of the list” Step 2: input “Element” Step 3: using sum function calculate summation of all numbers. Step 4: calculate average. Example code # Average of a list A=list() n=int(input("Enter the size of the List ::")) print("Enter the number ::") for i in range(int(n)): k=int(input("")) A.append(int(k)) sm=sum(A) avg=sm/n print("SUM = ",sm) print("AVERAGE = ",avg) Output Enter the size of the List ::5 Enter the number:: 10 20 30 40 50 SUM = 150 AVERAGE = 30.0
Read MorePython program maximum of three.
Given three number a b and c, our task is that we have to find the maximum element in among in given number. Example Input: a = 2, b = 4, c = 3 Output: 4 Algorithm Step 1: input three user input number. Step2: Add three numbers to list. Step 3: Using max() function to find the greatest number max(lst). Step 4: And finally we will print maximum number. Example Code def maximum(a, b, c): list = [a, b, c] return max(list) # ...
Read MorePrint powers using Anonymous Function in Python?
Here we used anonymous (lambda) function inside the map() built-in function. In Python, anonymous function is defined without name, its defined using lambda keyword. Algorithm Step 1: input n Step 2: input p Step 3: use anonymous function. Step 4: display result. Example Code # To display the powers of any number using anonymous function n = int(input("Enter how many terms want to display??")) p = int(input("Enter the number want to calculate power ::")) # use anonymous function cal = list(map(lambda i: p ** i, range(n))) # display the result print("The total terms is ::>", ...
Read MoreSecond most repeated word in a sequence in Python?
The string is given, our task is to find out the second repeated word. Here we Counter(iterator) for creating dictionary which contains word as key and its frequency as value. Algorithm Step 1: Create user define list. Step 2: Then convert list into a dictionary. Step 2: Next get the values and sort them in descending order. Step 3: Then the second element is the second largest value. Step 4: Next again traverse whole dictionary and display key whose value is equal to second largest element. Example code # To print Second most repeated word in a ...
