Concept explainers

Operations

In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.

Basic Operators

An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.

Division Operator

We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:

Modulus Operator

Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.

Operators

In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.

Question

You are given a file consisting of students’ names in the following form: lastName, firstName middleName. (Note that a student may not have a middle name.) Write a program that converts each name to the following form: firstName middleName lastName. Your program must read each student’s entire name in a variable and must consist of a function that takes as input a string, consists of a student’s name, and returns the string consisting of the altered name. Use the string function find to find the index of ,; the function length to find the length of the string; and the function substr to extract the firstName, middleName, and lastName.

1. Write a function in python to count the number of lines from a text file "story.txt" which is not starting with an alphabet "T". Example: If the file "story.txt" contains the following lines: A boy is playing there. There is a playground. An aeroplane is in the sky. The sky is pink. Alphabets and numbers are allowed in the password. The function should display the output as 3 5.2.pdf
Write a Python script that extracts and prints a single record from an input file in which the data is organized by line. Each line contains the name of a person (possibly containing multiple words) followed by the year of his birth. Abbas ibn Firnas ibn Wirda: 809 Muhammad ibn Musa al-Khwarizmi: 780 Abu Al-Walid Muhammad Ibn Alımad Ibn Rushd: 1126 The program uses function extractDataRecord with the specification: @param infile the input text file object @return parts a list containing the name (string) in the first element and the year of birth (int) in the second element.

Write a program that creates a function to read multiple DNA sequences from the user and writes them in “Sequence.txt” file. Create another function that takes a string of DNA as argument and returns its transcribed sequence. Now read each sequence from Sequence.txt file, transcribe it, calculate its length & nucleotides frequencies. Store this modified information in a formatted way in another file named as “ModifiedSequences.txt”. In the end display contents of both the files. ***coding language python use bio python necessarily for solving this question***don't use arrays or pointers keep the program as basic as possible*** paste the scereenshots of input and output and also copy paste the program Write comments on each and every line of program

The file text.txt contains a sentence text written in all small letters and does not have any punctuation marks, no numbers, no symbols except for spaces. You are required to write a program which accepts an operation code, and zero to two inputs depending on the operation code. Based on the operation code, you will call three versions of the overlaoded function textProcessing as follows: ● Operation 0: The function removes all vowels from the ORIGINAL sentence. The vowels considered are the small letters (a, e, i, o, u y, and w). • Operation 1: The code further asks for one lowercase letter to be input by the user. If the character is not a lower case letter, the code outputs Invalid.The function returns the distance (difference) between the letter first occurence and last occurence in the text. If the letter does not occur in the sentence, it returns 0. • Operation 2: The code asks for two lowercase letters to be input by the user. If the characters are not lower case letters, the…

Please use Python for this question. Please format code properly when answering the question. Write a standalone function partyVolume() that takes accepts one argument, a string containing the name of a file. The objective of the function is to determine the Volume object that is the result of many people at a party turning the Volume up and down. More specifically: the first line of the file is a number that indicates the initial value of a Volume The remaining lines consist of a single character followed by a space followed by a number. The character will be one of ‘U” or ‘D’ which stand for “up” and “down” respectively. The function will create a new Volume object and then process each line of the file by calling the appropriate method of the Volume object which changes the value of the Volume. The function then returns the final Volume object. Guidelines/hints: This is a standalone function, it should NOT be inside (indented within) the class. It should be listed in…
