Implement a program called genes. py that does the following: a. Reads a DNA sequence t as command-line argument b. Reads strings (one by one) representing genes from standard input until EOF (use the functions stdio. isEmpty() and stdio. readString()), and for each string s i. Constructs a Gene object g from s ii. Writes g iii. Writes whether g contains the DNA sequence t or not c. Writes the percentage of genes that contain t, up to two decimal places

Following are the code to this question:

import sys#import package sys

class Gene:#defining a class Gene

   gString = ""#defining a string variable

   def __init__(self, gString):#defining a constructor

       self.gString = gString#defining object to hold string value

gCount = 0#defining integer variable

mCount = 0#defining integer variable

t = input();#input value from user end

for s in sys.stdin:#defining for loop to check input value

   g = Gene(s)#defining g variable to pass value in class parameter

   gCount +=1#incrementing the value of gCount variable

   if(t in s):#defining if block to check input

       mCount +=1#incrementing the matchCount value

       print( g.gString,"True")#print value True

   else:#else block

       print( g.gString,"False")#print value False

   print("{:.2f}".format(mCount*100/gCount))#print percentage value

Output:

Explanation:

In the code, a class Gene is declared, that defines a string variable geneString, and creates its constructor, and store the string variable value.

In the next step, a three-variable gCount, mCount, and t defined, in which variable "t" is used for an input value, and inside the for loop, it uses the conditional statement, that checks its value and increments the integer value, and print true or false as a message.
