- File Iteration: Introduction A text file is essentially a sequence of lines. Here is a typical coding pattern for processing each line of a file in turn: Open the file for reading. Use a for loop to iterate over the lines of text, executing a block of one or more statements to process each line. Close the file. Finish processing (print, return, etc.) if needed NOTE: You will need to use this pattern, or some variation of it, to solve the remaining coding problems in this assignment. As the following for loop iterates through each line of the file, the loop variable (`line`) represents the current line of the file as a string of characters. myFile = open("someTextFile.txt", "r") for line in myFile: do something on each iteration do a second thing on each iteration etc... myFile.close() PROBLEM: Read a string from standard input using python. Then, iterate over a text file called "cards.txt" and, for each line of the file that starts with the string read from standard input,…arrow_forwardC++ A teacher is requiring her students to line up in alphabetical order, according to their first names..For example, in one class Chapel, Christine would be at the front and Uhura, Nyota would be last. The program will get the names from a file using getline since the file name includes spaces. The names should be read in until there is no more data to read. The program should prompt the user for the file name and read the data from the file. Note that these names might include spaces; handle your input accordingly. The expected output is two names; do not show the entire file. Do not use arrays or sorting for this problem.arrow_forwardC++ A teacher is requiring her students to line up in alphabetical order, according to their first names..For example, in one class Chapel, Christine would be at the front and Uhura, Nyota would be last. The program will get the names from a file. The names should be read in until there is no more data to read. The program should prompt the user for the file name and read the data from the file. A suitable file of names (List of Random Names) is provided on Moodle. Note that these names might include spaces; handle your input accordingly. The expected output is two names; do not show the entire file (or you will regret that code when you do the associated programming quiz that processes thousands of names).

- JAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…arrow_forwardcan someone help me with this problem in C and explain how to do it step by steparrow_forwardThis Python Lab 9 Lab: Write a file copying program. The program asks for the name of the file to copy from (source file) and the name of the file to copy to (destination file). The program opens the source file for reading and the destination file for writing. As the program reads each line from the source file and it writes the line to the destination file. When every line from the source file has been written to the destination file, it close both files and print “Copy is successful.” In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that both “add-copy.py” is identical to “add.py” because “add-copy.py” is a copy of “add.py”. Sample run: Enter file to copy from: add.py Enter file to copy to : add-copy.py Copy is successful. Source file: add.py print("This program adds two numbers") a = int(input("Enter first number: ")) b = int(input("Enter second number: ")) print(f"{a} + {b} = {a+b}") Destination file:…arrow_forward
- #Problem #1 Searching for a Item in a File Write a program named SearchFile.py that reads in a list of items from a text file and looks for the presence of one that the user enters from the keyboard. During the search, have a loop that ends when they type in DONE for the word. For ours, we will search for a bird name but the idea would be applicable for any searching in a file.arrow_forwardProgram 5: Word Frequencies (Concordance) Use a text editor to create a text file (ex: myPaper.txt) It should contain at least 2 paragraphs with around 200 or more words. Write a Python program (HW19.py) that asks the user to provide the name of the text file. Be SURE to check that it exists!Do NOT hard-code the name of the file! Use the entry provided by the user! read from the text file NOTE: (write your program so that it ONLY works if it reads from the file specified by the user). Your program will produce a dictionary of words with the number of times each occurs. It maps a word to the number of times the word occurs Key: a word Value: the number of times the word occurs in the text. The report should be an ALPHABETIZED output table, listing the word and the number of occurrences. NOTES: The input sequence can be words, numbers or any other immutable Python object, suitable for adict Ignore case – apple is the same as Apple is the same as APPLE, etc. Discard all…arrow_forwardWrite in python.arrow_forward

Help him to make a program to search a name in lines of names. Format Input The input consists of several lines in testdata.in file. The first line of the input will consist of an integer T denoting the number of test cases. Each test case will start with an integer N. The next N lines will consist of a string S denoting the K-th name. After N lines of names will consists of a string F, a name that needs to be found. Format Output For each test case, print "Case #X: Y" where X is the number of test case starting from 1, and Y is the index where the name is. If the name isn’t found, Y will be “Not found” without quotation. If there are repeated names in 1 test case, then output the first found name's index.

Complete the modify function to change the brightness of the image. The parameter m is a multiplication factor. modify will will multiply each pixel by m - that means you need to multiply the red, green, and blue channels by m, create a new pixel with new red, green, and blue values, and replace the old pixel with the new pixel. Be sure none of the red, green, and blue values exceed 255 (if a value is greater than 255, set it to 255). Your program should work for images of any size. A good example is the sepia tone exercise. Do not change the main function, except to try different values for the multiplication factor.
