If a file is opened for writing but it already contains data, it will append to the file. overwrite the file. delete the file. throw an error.
Consider the following code segment: done = False while not done : try : filename = input("Enter the file name: ") inFile = open (filename, "r") 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 = inFile done = True done = not inFile done = False
Python programs are saved as ordinary text files (with the extension.py). This means we can read them and process them just like any other data file. Write a function num_whiles (filename) that reads the Python program file with the given filename and returns a count of the number of while loops found in that program. More precisely, your function should return the number of lines starting with (possibly) some white space followed by the string 'while , i.e. the word while with a space at the end. This is usually, but not necessarily, the same as the number of while loops in the program, but we won't worry about that here. In the first example below, the file testo.py contains the following program: i = 0 while i 0: \n") # ...and one indented while while_file.write(" while < 1: \n") while_file.close() # Now use it for testing print (num_whiles("while_file.py"))

CODE IN PYTHON PLEASE The objective is to create a code in Python that can extract the columns highlighted in blue (Column T and AB3) and output them to a .txt file. The code should be able to generate the text file with the columns that are highlighted in blue and store them on a separate folder. Below shows how the Test.xlsm file looks like as well as how the text file should look like when the code extracts and outputs it. Google drive to access Test.xlsm file: https://drive.google.com/drive/folders/16utzb5_h7yMCN8_13E_JqasfcpykZOYr?usp=sharing What my code outputs is shown in the picture (O1.png) What I would like for my code to output is the columns next to each other (Right Example.png) The current code is able to output Columns T and AB3 but I am not able to output them next to each other as shown above.

Directions: Typing make at the command line should create executable named bitflip. Only bitflip.c and Makefile are included in the input unless permission is given for any other files. Program should have consistent indentation. Code should be readable with good variable and function names. No use of "break or continue statements" except in a switch. Program must exit with a return code of 0 on success and an error code in other cases. The program used getopt to parse the command line. Whenever an error occurs on the command line the user is given the usage statement and an appropriate error message if needed. If the -o option is used the output will go to a file named as specified without changing the filename at all otherwise it will go to stdout. -e option works as specified using bitwise operations. -f option works as specified using bitwise operations. -a option works as specified using bitwise operations. -s option works as specified using bitwise operations. Program outputs…
