- 7. Create timestamp decorator. Instructions: • Create a file named log.py and create decorator inside called timestamp The decorator should print the current time then afterwards print anything the is being decorated (see examples below) Hint: - Use time.ctime() Examples: Input (in file called test.py): from log import timestamp Otimestamp def hi(): print('hi') def main(): hi () main() Output: $ python3 test.py Wed Oct 19 17:27:12 2022 hiInstructions Add a command to this chapter’s case study program that allows the user to view the contents of a file in the current working directory. When the command is selected, the program should display a list of filenames and a prompt for the name of the file to be viewed. Be sure to include error recovery in the program. If the user enters a filename that does not exist they should be prompted to enter a filename that does exist. An example of the program input and output is shown below: /root/sandbox 1 List the current directory 2 Move up 3 Move down 4 Number of files in the directory 5 Size of the directory in bytes 6 Search for a file name 7 View the contents of a file 8 Quit the program Enter a number: 7 Files in /root/sandbox: filesys.py example.txt Enter a file name from these names: example.txt THIS IS CONTENT OF AN EXAMPLE FILE. /root/sandbox 1 List the current directory 2 Move up 3 Move down 4 Number of files in the directory 5 Size of the directory in bytes 6…help with Python.....paste indented code here QUESTION 10 Implement the following with try...except:1) Assign a variable to the filename newFile.txt.2) Remove the file, newFile.txt from the current working directory.3) Prompt "Remove Complete" if the file can be removed. Otherwise, prompt "INCOMPLETE". Example Output (assume newFile.txt does not exist)INCOMPLETE
- Consider the following code segment: done = False while not done : try : filename = input("Enter the file inFile open(filename, "r") %3D except IOError : print("Error: File not found.") It is supposed to keep on prompting the user for file names until the user provides the name of a file that can be opened successfully. What line of code should be placed in the blank to achieve this goal? Select one: done = True done = inFile done = not inFile done = FalseDeadlock on File Requests happens if jobs are allowed to request and hold files for the duration of their execution Select one: O True O FalseWrite a program that writes user input to a text file and then reads the contents from that file. You will need to perform the following steps. Prompt the user for the name of a file to append to and then another prompt for them to enter a sentence. Open the file they requested in append mode and write the user_sentence to this file. Don't forget to close the file when you are done writing to it (explicitly or implicitly). Open the file you just wrote to in read mode and read the contents of the file. Print the complete file contents to the console/shell. Provide comments in your code to explain the logic used. Ensure your program works as expected by testing it with different sentences.
- No files need to be provided , the file foo is just an example.Hello help me writing a program that takes the text file name from the user and reads the contents of that file.All I need is the main.cpp file Programming Specifications: Task: Two files have been provided (wordcounter.h and wordcount.cpp). You must open a text file, read in each word until end of file, add each word to the WordCount library and print the report. Your program must request a filename of a text file that contains words to count. You must check to see if it is a valid file and issue an error message if not and request a new file name until a valid one is entered. You must have at least one function that either passes in a parameter and at least one function that returns a value. You can have a single routine that does both. You must declare the class object properly, use AddWord() to add the word to the catalog and use PrintSummary() to produce the output. Design Considerations: The file will contain only words (no punctuation or special characters) less than or equal to 13 letters. There will be no limit to the number of words. You must open the file and read each…
