pls code in pythonplagiarism: This Boolean function takes two filenames. If any line occurs in both files, return True.If not, return False. I suggest using nested loops. With nested loops, we call the loop that is in thebody of the other loop, the "inner loop". The loop that contains the inner loop is the "outer loop". Openthe second file inside the outer loop:for line1 in file1:file2 = open(fname2)for line2 in file2:Python only lets you read the file once per open, so you need this order of instructions. Make sure yourreturn False is outside of both loops. Otherwise, you will only compare the first two lines of thefiles. Make sure you close the file that gets read repeatedly after the inner loop but still inside the outerloop.Here is some (more complete) pseudocode to get you started:open file 1for line1 in file 1open file 2for line2 in file 2:if line1 == line2:return Trueclose file 2return False

PYTHON-Assume you have a file that has two columns separated by a comma. The first column contains gene accession numbers, and the second column contain their nucleotide sequence. For example: ABC123, AAGTCTTCCCTAAGCCC... KHJ456, TTCGGTCATACTATTC... NMG789, GCTACTCGATGCTA.... .... The file can contain any number of rows. Write a program that reads in this file (you can create one to test your code with, use TextEdit or Notepad) and creates a dictionary, where the keys are the accession numbers and the values are the sequences. Print out to the screen the dictionary pairs that you created.
python help, fill in the "your response" parts Write function quoteByNum() that takes as input the name of a file (as a string) and an index i (as an integer). The file will contain quotes, one per line. The function should open the file, read the file, close the file, and return the i-th quote (i.e. the i-th line in the file), assuming that the quote numbering starts at 0. Test your solution on file Wilde_Quotes.txt.>>> quote("Wilde_Quotes.txt", 5)'At twilight, nature is not without loveliness, though perhaps its chief use is to illustrate quotations from the poets.\n'>>> quote("Wilde_Quotes.txt", 0)'A little sincerity is a dangerous thing, and a great deal of it is absolutely fatal.\n'>>> quote("Wilde_Quotes.txt", 23)'Patriotism is the virtue of the vicious. \n'>>> def quoteByNum(file, int1): your response (docstring) infile = open(file) # your response content = infile your…
please code in pythonredact_file: This function takes a string filename. It writes a new file that has the same contentsas the argument, except that all of the phone numbers are redacted. Assume that the filename has onlyone period in it. The new filename is the same as the original with '_redacted' added before theperiod. For instance, if the input filename were 'myfile.txt', the output filename would be'myfile_redacted.txt'. Make sure you close your output file.The first hard task in this function is to make the output filename from the input filename that waspassed in. You can break it into two pieces by splitting on the dot or by using the index method andslicing. Then put it back together again using string concatenation.We are also working with files in this one. To open a file with a filename stored in the variable fname,in read mode use the open function as such: fp = open(fname). You will need to open the outputfile in write mode: open(fname, 'w'). Then you can traverse the…
The python function file_first_chars takes one parameter, fname, the name of a text file, and returns a string made up of the first character from each line in the file. You may assume there are no blank lines in the file. Hint: Use a for loop to iterate over the lines of the file and accumulate the string of first characters.
