<span>It can be true and is really necessary for this type of things when fittings in ways that prevent tension at joints and terminal screws. So, Flexible cords are finely stranded for flexibility, so straining a cord can cause the strands of one conductor to loosen from under the many joints.</span>

Write a function wordcount() that takes the name of a text file as input and prints the number of occurrences of every word in t
o-na [289]

Answer:

I am writing a Python program. Let me know if you want the program in some other programming language.        

import string  #to use string related functions

def wordcount(filename):  # function that takes a text file name as parameter and returns the number of occurrences of every word in file

   file = open(filename, "r")  # open the file in read mode

   wc = dict()  # creates a dictionary

   for sentence in file:  # loop through each line of the file

       sentence = sentence.strip()  #returns the text, removing empty spaces

       sentence=sentence.lower() #converts each line to lowercase to avoid case sensitivity

       sentence = sentence.translate(sentence.maketrans("", "", string.punctuation))  #removes punctuation from every line of the text file

       words = sentence.split(" ")  # split the lines into a list of words

       for word in words:  #loops through each word of the file

           if len(word)>2:  #checks if the length of the word is greater than 2

               if word in wc:  # if the word is already in dictionary

                   wc[word] = wc[word] + 1  #if the word is already present in dict wc then add 1 to the count of that word

               else:  #if the word is not already present

                   wc[word] = 1  # word is added to the wc dict and assign 1 to the count of that word                

   for w in list(wc.keys()):  #prints the list of words and their number of occurrences

       print(w, wc[w])  #prints word: occurrences in key:value format of dict        

wordcount("file.txt") #calls wordcount method and passes name of the file to that method

Explanation:

The program has a function wordcount that takes the name of a text file (filename) as parameter.

open() method is used to open the file in read mode. "r" represents the mode and it means read mode. Then a dictionary is created and named as wc. The first for loop, iterates through each line (sentence) of the text file. strip() method is used to remove extra empty spaces or new line character from each sentence of the file, then each sentence is converted to lower case using lower() method to avoid case sensitivity. Now the words "hello" and "Hello" are treated as the same word.

sentence = sentence.translate(sentence.maketrans("", "", string.punctuation))  statement uses two methods i.e. maketrans() and translate(). maketrans() specifies the punctuation characters that are to be deleted from the sentences and returns a translation table. translate() method uses the table that maketrans() returns in order to replace a character to its mapped character and returns the lines of text file after performing these translations.

Next the split() method is used to break these sentences into a list of words. Second for loop iterates through each word of the text file. As its given to ignore words of length 2 or less, so an IF statement is used to check if the length of word is greater than 2. If this statement evaluates to true then next statement: if word in wc:   is executed which checks if the word is already present in dictionary. If this statement evaluates to true then 1 is added to the count of that word. If the word is not already present  then the word is added to the wc dictionary and 1 s assigned to the count of that word.

Next the words along with their occurrences is printed. The program and its output are attached as screenshot. Since the frankenstein.txt' is not provided so I am using my own text file.

¿Cómo es la onda percibida por un osciloscopio cuando hablamos de sonido? ¿Qué parámetros podemos observar en ella?
frozen [14]

Answer:

Las ondas de sonido, que es una onda longitudinal, son producidas por la vibración de un objeto de tal manera que (la onda de sonido requiere un medio de viaje, líquido sólido o gas) la dirección del sonido es la misma que la dirección de la vibración y como la el ancho de la vibración (hacia adelante y hacia atrás) aumenta, la amplitud de la vibración aumenta y el sonido es más fuerte

Un micrófono conectado al osciloscopio recoge el medio de aire vibrante de la onda de sonido de la energía de la onda de sonido y lo convierte (produce) señales eléctricas y electrónicas. El osciloscopio, que está diseñado para mostrar señales electrónicas, muestra las señales electrónicas transmitidas por el micrófono en la pantalla con los mismos valores de amplitud y frecuencia que el volumen y el tono de la onda de sonido, respectivamente.

Las características observables son;

1) El volumen o el volumen de la onda de sonido que se muestra como la amplitud) en el cátodo, con una amplitud más alta que representa un sonido más fuerte

2) El tono de la onda de sonido se muestra como el espaciado de onda en el osciloscopio, el sonido de tono más alto se muestra por las ondas que se acercan en la pantalla
