I am trying to read in a text file called "lines.txt" that holds an entire dictionary of words with multiple words on each line. I am supposed to find the longest word in the file and the line number it is on. So far I know that I am supposed to have a line counter when initializing the first get line() to 1 but I am confused on how to parse through it.
Write a program that computes and prints the average of the numbers in a text file. You should make use of two higher-order functions to simplify the design. Ask the user for the name of the .txt file that contains the list of numbers. Include your code as usual in a .txt AND .py file. Create and use a .txt file to test your code using the numbers 78, 54, 22, 90, 15, 7.
i have already asked this question and the answer did not work for me: Write a program that first reads in the name of an input file and then reads the file using the csv.reader() method. The file contains a list of words separated by commas. Your program should output the words and their frequencies (the number of times each word appears in the file) without any duplicates. Ex: If the input is: input1.csv and the contents of input1.csv are: hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy the output is: hello 1 cat 2 man 2 hey 2 dog 2 boy 2 Hello 1 woman 1 Cat 1 Note: There is a newline at the end of the output, and input1.csv is available to download.
13. Write function quote() that takes as input the name of a file (as a string) and anindex i (as an integer). The file will contain quotes, one per line. The function shouldopen the file, read the file, close the file, and return the i-th quote (i.e. the i-th line in thefile), assuming that the quote numbering starts at 0. Test your solution onfile Wilde_Quotes.txt.>>> quote("Wilde_Quotes.txt", 5)'At twilight, nature is not without loveliness, thoughperhaps its chief use is to illustrate quotations from thepoets.\n'>>> quote("Wilde_Quotes.txt", 0)'A little sincerity is a dangerous thing, and a great dealof it is absolutely fatal.\n'>>> quote("Wilde_Quotes.txt", 23)'Patriotism is the virtue of the vicious. \n'>>>
Q14: The function f(x) = e can be represented in a Taylor series by: ex = -Σ n! 72=0 Write a program in a script file that determines e by using the Taylor series representation. The program calculates e by adding terms of the series and stopping when the absolute value of the term that was added last is smaller than 0.0001. Use the program to calculate e², e05 and eª This problem can be solved by using while - end loop because : ONumber of passes not known OIt is a Taylor series All of the given O Number of passes is predetermined O Estimated error value must be calculated
PYTHON: I need to get the avg statement out of the loop so that the output prints correctly. Any suggestions. Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam…

Note: A input file named "input.txt" is attached with this test. Read the file as input and save the output in the required format in a separate file named “output.txt". Given X is an N-digit odd positive integer such that X is divisible by 3 but not by 9. NOTE: There should not be any leading zeros in X. 003 is not a valid three-digit even integer. Input Format: • The first line of input contains a single integer T, denoting the number of test cases. • The first and only line of each test case contains a single integer N, denoting the numbe of digits in X. Output Format: For each test case, output a single line containing N-digit even positive integer X, such that X is divisible by 3 but not by 9.

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…
Use the functions from the previous three problems to implement a pro-gram that computes the sum of the squares of numbers read from a file. Your program should prompt for a file name and print out the sum of thesquares of the values in the file. Hint: Use readlines ()
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
You are not allowed to use strings, cstrings!!! A C++ Program: We have obtained some files that are encoded with a simple method of writing the text from end to beginning. We therefore need a program that reads a file named codedfile.txt that is 500 chars or less and generates a file call clearfile.txt that has the characters stored in revers order. For example, if codedfile.txt contains the characters dlrow olleh, then after running the program clearfile.txt should contain hello world. Do not use strings or cstrings for reasons explained please!
