- In Python do the following: 1) Reading from Files:Suppose we have a text file (‘readfile.txt’) containing the following lines:Hello!My name is Mary Summers.This is my resume.We want to read its contents into Python. Write a code that will load the entire file into a string.Please know that when you write code to open a file, the file is assumed to be in the same directory asyour program. If it is in a different directory, then you need to specify that.arrow_forwardcan you do it pythonarrow_forwardENGAGE MINDTAP -Using a Counter-Controlled while Loop in Java Using a Counter-Controlled while Loop ? Summary In this lab, you use a counter-controlled while loop in a Java program provided for you. When completed, the program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. The data file contains the necessary variable declarations and some output statements. Instructions 1. Ensure the file named Multiply.java is open. 2. Write a counter-controlled while loop that uses the loop control variable to take on the values O through 10. Remember to initialize the loop control variable before the program enters the loop. 3. In the body of the loop, multiply the value of the loop control variable by 2 and by 10. Remember to change the value of the loop control variable in the body of the loop. 4. Execute the program by clicking Run. Record the output of this program. Grading When you have completed your program, click the Submit button to record your…arrow_forward
- Answer the given question with a proper explanation and step-by-step solution. 1- Write code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 through 100 to the file, then closes the file.arrow_forward(True/False): A file’s directory entry contains the file’s starting sector number.arrow_forwardWhen you open a file for reading, what happens if the file does not exist? When you open a file for writing, what happens if the file already exists?arrow_forward

Comment out each step please!!!arrow_forwardcan you show me this in pythonarrow_forwardObjective:Design and implement a word unscrambler game in Java.Details:Your program should read in a random word from a file called words.txt (note the lack of capitalization) that you provide. There should not be any hard limit on the number of words in the file. If words were added/removed from the file, your program should recognize such changes of the words.txt and handle appropriately next time it runs. The file should contain one word per line. To read a random word you can generate a random number between 1 and the number of lines, and skip n-1 lines before reading the word. Scramble the word by swapping random pairs of letters a random number of times. Display the scrambled word with character indexes on top. Assume that the word is always no more than ten characters (so that index can be within 0-9 range, inclusive).Offer the user a menu with the following choices:• Enter 1 to swap a pair of lettersIf this option is selected prompt the user to enter two indexes and swap the…arrow_forward
