Formatted text in Linux Terminal using Python
In this section, we will see how to print formatted texts in Linux terminal. By formatting, we can change the text color, style, and some special features. Linux terminal supports some ANSI escape sequences to control the formatting, color and other features. So we have to embed some bytes with the text. So when the terminal is trying to interpret them, those formatting will be effective. The general syntax of ANSI escape sequence is like below − \x1b[A;B;C A is the Text Formatting Style B is the Text Color or Foreground Color C is the Background ...
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 ...
Read MorePython program to find Union of two or more Lists?
Union operation means, we have to take all the elements from List1 and List 2 and all the elements store in another third list. List1::[1, 2, 3] List2::[4, 5, 6] List3::[1, 2, 3, 4, 5, 6] Algorithm Step 1: Input two lists. Step 2: for union operation we just use + operator. Example code # UNION OPERATION A=list() B=list() n=int(input("Enter the size of the List ::")) print("Enter the Element of first list::") for i in range(int(n)): k=int(input("")) A.append(k) print("Enter the Element of second list::") for i in range(int(n)): ...
Read MorePython program to find Intersection of two lists?
Intersection operation means, we have to take all the common elements from List1 and List 2 and all the elements store in another third list. List1::[1, 2, 3] List2::[2, 3, 6] List3::[2, 3] Algorithm Step 1: input lists. Step 2: first traverse all the elements in the first list and check with the elements in the second list. Step 3: if the elements are matched then store in third list. Example code #Intersection of two lists def intertwolist(A, B): C = [i for i in A if i in B] ...
Read MorePython program to convert an array to an ordinary list with the same items
The array is given. Our task is to convert an array to an ordinary list. We solve this problem with the help of tolist() function. This function return the array as a (possibly nested) list. Algorithm Step 1: Given an array. Step 2: convert the array to a list using tolist() function. Step 3: Display list Example Code #Python program to convert an array to an ordinary #list with the same items from array import * def arraytolist(A): lst = A.tolist() # list print("The List Is ::>",lst) # Driver code A= array('i', [20,30,60]) # array arraytolist(A) Output The List Is ::> [20, 30, 60] The List Is ::> [20, 30, 60]
Read MoreInplace operator in Python
Definition - In-place operation is an operation that changes directly the content of a given linear algebra, vector, matrices(Tensor) without making a copy. The operators which helps to do the operation is called in-place operator. Eg: a+= b is equivalent to a= operator.iadd(a, b) There are some operators are used for In-place operation. iadd() This function is used to assign the current value and add them. This operator does x+=y operation. In case of strings, numbers assigning is not performed. Example a =operator.iadd(1, 3); print ("The result after adding : ", end="") print(a) Output ...
Read MorePython program to generate all possible valid ID address from given string
String is given. String contains only digit. Our task is to check all possible valid IP address combinations. Here first we check the length of the string then split by ".". Then we check the different combination of ".". Example Input : "255011123222" It's not a valid IP address. Input : 255011345890 Valid IP address is 255.011.123.222 Algorithm Step 1: First check the length of the string. Step 2: Split the string by ".". We will place 3 dots in the given string. W, X, Y, and Z are numbers from 0-255 the numbers cannot be ...
