Python program to check a sentence is a pangrams or not.
Given a sentence. Our task is to check whether this sentence is pan grams or not. The logic of Pan grams checking is that words or sentences containing every letter of the alphabet at least once. To solve this problem we use set () method and list comprehension technique. Example Input: string = 'abc def ghi jkl mno pqr stu vwx yz' Output: Yes // contains all the characters from ‘a’ to ‘z’ Input: str='python program' Output: No // Does not contains all the characters from ‘a’ to 'z' Algorithm Step 1: create a string. Step 2: ...
Read MorePrint m multiplies of n without using any loop in Python.
Given a number n, print m multiplies of n without using any loop. Here we use recursive function. Examples Input: n = 15 Output: 15 10 5 0 5 10 15 Algorithm Step 1: Given n. Step 2: If we are moving back toward the n and we have reached there, then we are done. Step 3: If we are moving toward 0 or negative. Step 4: If m is greater, then 5, recursive function with true flag else recursive function is false. Step 5: If m is not greater than 5 then flag is false. ...
Read MoreZip function in Python to change to a new character set.
Given a 26 letter character set, here we are using a new character set. And another character set just like alphabet set (a, b, c........z), then our task is to make a relation between new character set and that alphabet set. Example New character set: qwertyuiopasdfghjklzxcvbnm Input: "wwmm" Output: bbzy Algorithm Step 1: Given a new character set and input the string to make a relation. Step 2: and the original character set also given below. Step 3: Create a dictionary, we use here map technique, we map the English character set and new given character set, ...
Read MorePython program to find the length of the largest consecutive 1's in Binary Representation of a given string.
Given the number, find length of the longest consecutive 1's in its binary representation. Example Input: n = 15 Output: 4 The binary representation of 14 is 1111. Algorithm Step 1: input the number. Step 2: use one counter variable c=0. Step 3: Count the number of iterations to reach i = 0. Step 4: This operation reduces length of every sequence of 1s by one. Example code # Python program to find # length of the longest # consecutive 1s in # binary representation of a number. def maxlength(n): # ...
Read MorePython program to print all the common elements of two lists.
Given two lists, print all the common element of two lists. Examples − Input : L1 = [5, 6, 7, 8, 9] L2 = [5, 13, 34, 22, 90] Output : {5} Explanation The common elements of both the list is 5. Algorithm Step1 : create two user input lists. Step2 : Convert the lists to sets and then print set1&set2. Step3 : set1 and set2 returns the common elements set, where set1 is the list1 and set2 is the list2. Example Code # Python ...
Read MorePython program multiplication of two matrix.
Given two user input matrix. Our task is to display the addition of two matrix. In these problem we use nested List comprehensive. Algorithm Step1: input two matrix. Step 2: nested for loops to iterate through each row and each column. Step 3: take one resultant matrix which is initially contains all 0. Then we multiply each row elements of first matrix with each elements of second matrix, then add all multiplied value. That is the value of resultant matrix. Example Code # Program to multiply two matrices A=[] n=int(input("Enter N for N x N matrix: ")) ...
Read MorePython program to calculate BMI(Body Mass Index) of your Body
We have to enter our height and weight. Our task is to calculate BMI using formula. Algorithm Step 1: input height and weight of your body. Step 2: then applying the formula for calculation BMI. Step 3: display BMI. Example Code height = float(input("Enter your height(m): ")) weight = float(input("Enter your weight(kg): ")) print("Your BMI is: ", round(weight / (height * height), 2)) Output Enter your height (m): 5.8 Input your weight (kg): 64 Your body mass index is: 1.9
Read MorePython GNU readline Interface
The readline is UNIX specific module. It defines a number of functions to read and write history files in easier way from python interpreter. We can use this module directly or using the rlcompleter module. This module settings may affect the built-in input() method prompt and also the interactive prompt. For the MAC based system (on MAC OS X) this readline module can be implemented using the libedit library. The libedit configuration is different from GNU readline. To use this module, we need to import the readline module in the python code import readline Some methods of ...
Read MoreGenerate Secure Random Numbers for Managing Secrets using Python
To generate secure random numbers cryptographically we can use the secrets module in python. This module is helpful to create secure password, account authentication, security tokens or some related secrets. To use the classes and modules of the secrets module, we should import that module into our code. import secrets Random Numbers The secrets module is used to access some secure source of randomness. That is provided by the operating systems. Classes and functions, related to random numbers of the secrets modules are − Class secrets.SystemRandom It is a class to generate random numbers, by using some highest ...

To display web based documents to users by using python, there is a module called webbrowser. It provides high level interface to handle web documents. On UNIX based system, this module supports lynx, Netscape, Mosaic etc browsers. For Windows and Macintosh, it uses the standard browsers. To use this module, we need to import the following module. import webbrowser The webbrowser module has different methods, and exceptions, these are as follows − Exception webbrowser.Error This error will raise when there is an error in the webbrowser interface. Method webbrowser.open(url, new=0, autoraise=True) This method is used to display the ...
