Python create function writeAFile() to meet the conditions below - accept two parameters: a string (name of a file) a list - add a meaningful docstring - open the filename for writing - write to the file all of the items in the list. - Each item should be on a separate line in the file. - Count the number of lines written to the file. --- don't forget to close the file - return the number of written lines Restriction: you may NOT use the built-in function len() - params: string list - return: integer

Do the following questions: a. Create a function that takes a source file name and destination file name as parameters and copies all the characters from the source file to the destination file except #. b. A list L1 = [10,3,44,52] has the following elements. Write a program that replaces all the number divisible by 3 with 'Yes' and not divisible by 3 by 'No'.
Phyton: Program 6: Write a program that allows the user to add data from files or by hand. The user may add more data whenever they want. The print also allows the user to display the data and to print the statistics. The data is store in a list. It’s easier if you make the list global so that other functions can access it. You should have the following functions: · add_from_file() – prompts the user for a file and add the data from it. · add_by_hand() – prompts the user to enter data until user type a negative number. · print_stats() – print the stats (min, max, mean, sum). You may use the built-in functions. Handling errors such as whether the input file exist is extra credit. To print a 10-column table, you can use the code below: for i in range(len(data)): print(f"{data[i]:3}", end="") if (i+1)%10==0: print() print() Sample run: Choose an action 1) add data from a file 2) add data by hand 3) print stats 4)…
Python Help... Implement function distribution() that takes as input the name of a file (as a string). This one-line file will contain letter grades separated by blanks. Your function should print the distribution of grades, as shown.

please code in pythonredact_file: This function takes a string filename. It writes a new file that has the same contentsas the argument, except that all of the phone numbers are redacted. Assume that the filename has onlyone period in it. The new filename is the same as the original with '_redacted' added before theperiod. For instance, if the input filename were 'myfile.txt', the output filename would be'myfile_redacted.txt'. Make sure you close your output file.The first hard task in this function is to make the output filename from the input filename that waspassed in. You can break it into two pieces by splitting on the dot or by using the index method andslicing. Then put it back together again using string concatenation.We are also working with files in this one. To open a file with a filename stored in the variable fname,in read mode use the open function as such: fp = open(fname). You will need to open the outputfile in write mode: open(fname, 'w'). Then you can traverse the…
Exercise 6. Create a dictionary from a Text File: When a program incorporates a large dictionary, the dictionary is usually created from a file, such as a text file by using dict function to convert a list into a dictionary. Whenever a word in the original sentence is not a key in the dictionary, the get method places the word itself into the translated sentence. The file “Textese.txt” contains a word and its translation into textese. Write a program to create a dictionary with the file, ask the user to enter a simple sentence then translate it into textese. Define two function createDictionary (filename) and translate (sentence, dictionary). Then define a main function to test your functions
Please code in python:Create 2 .py files (decorators.py and main.py). Inside the main.py file, write a function that will take a list of integers, calculate the square root of each (use the math library or raise to a fractional power), and write the maximum number of the resulting numbers to the "result.txt" file. Inside the file for decorators, create 2 decorator functions, one must check the type of the input parameter, and if it is not a list of ints, raise a TypeError. The second decorator should leave only positive numbers in the input. Decorate the function from the main file with decorators from the second file. (You will need to import them) Use the data below to check if the program works: [60, -76, -45, 94, -65, -21, -53, 95, 82, -41, 57, 10, 98, -28, -23, -78, 24, 19, 87, -53 ] [-32, "99", -69, 66, 60, -68.98, 35, 23, -32, "-3", -6, -66, 97, 28, -44, 94, -.55, - 26, 58, -15]

(IN PYTHON) Problem 1 Write a function word_count() that performs the following actions: Opens a file called “novel.txt”. You can assume that the file exists and is located in the same directory as your code file. Reads in the contents of the file, and stores it in a variable called text. Uses the split() function to obtain a list containing all of the individual words in text. For details on how to use split(), you can consult this site: https://www.w3schools.com/python/ref_string_split.asp For this question, assume that all words will be separated by spaces.
