The following requirments that weren't mentioned for solving the following Python Code below: The provided code for alphabet, test_dups, test_miss, and histogram. Your implementation of the has_duplicates function. A loop that outputs duplicate information for each string in test_dups. Your implementation of the missing_letters function. A loop that outputs missing letters for each string in test_miss. Write a function called missing_letters that takes a string parameter and returns a new string with all the letters of the alphabet that are not in the argument string. The letters in the returned string should be in alphabetical order. Your implementation should use a histogram from the histogram function. It should also use the global variable alphabet. It should use this global variable directly, not through an argument or a local copy. It should loop over the letters in alphabet to determine which are missing from the input parameter. The function missing_letters should…
(5) Write a function called copy_even_lines() that takes two strings (filenames) as input parameters and copies every other line from the first file into the second. That is, counting from 0, it copies the 0th line, the 2nd line, the 4th line, etc. from the first file to the second file. You may assume that both files exist. (6) Write a python program that asks the user for two filenames and calls your function copy_even_lines() from (5) using those two filenames. If one or more files do not exist, your program must handle the exception by repeating the prompts until valid filenames are entered.
Hello, I have an assignment in the python program. Professor gives me a text like this: January.txt 217283921200.5619.18,29.15,78.75,212.10100,20,410.29 The first line is an account number, the second line is the beginning balance, the third line is withdrawn and the last line is deposits. How can I separate every single line to read them. Can I use the loop function? Below is the assignment direction. Thank you very much ___________________________________________________________ Complete the following program: a) Read in and store the data from the file called “January.txt”. This file includes the customer’s account number, beginning balance, withdrawals, and deposits. (In that order) Note: Make sure you look at the file before you begin the project! b) Prompt the user for his/her name and age. c) Convert the customer’s name to a username that consists of the first letter of the first name, the first 5 digits of last name, and the customer’s age.(All letters should be lowercase)…
Create a function get-random the parameters -count and the set -maximum and - minimum are mutually exclusive in POWERSHELL as follows: a)Write your own version of get-random that accepts all 3 of -count -min and -max as switches. It should call the standard version to produce results. Your version does not have to handle a list of values. b) The value of count should default to 1 and should have an alias of nItems. c) Write a loop to produce the requested # of items. d) Test your functions with float and integer values. e) Use the group-object cmdlet to prove that your function will generate repeats.

What is the output of following code segment?
This is for r Regarding a for loop, which of the following is not true? The for keyword must be followed by parentheses. Following the for statement, the code to be executed is recognized by it being indented. The number of times the loop will be performed is determined by the length of the vector passed to the for keyword. The for loop can contain other for loops.
Write code that uses the input string stream inSS to read input data from string userInput, and updates variables userMonth, userDate, and userYear. Sample output if the input is "Jan 12 1992": Month: Jan Date: 12 Year: 1992
- Write a for loop with index i that iterates over all consecutive integers from 4 to 10 and prints the current loop index to screen for each value of i. As always, be careful with indentation and use proper python syntax. - Same question as above, but add a logical (if) statement inside the loop that prints both the loop index and the message "is greater than 6" or "is less than or equal to 6" for the appropriate indices. Hint, use the syntax print(i, "string") to print both the loop index and the string at the same time.
