- 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…The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.Unfortunately, the change from int to Month means that it's harder to read Date objects from an input file, since it doesn't work if a user enters Date::jan. Write a toMonth function that can be used to enter a month as an integer. Throw invalid_argument if it fails. Month m = toMonth (3); // returns Month::mar udts.cpp 1 #include 2 #include 3 #include "date.h" using namespace std; 4 6. /** Construct a valid Month. 7 8. @param mm the month in the range 1-12 9. @exception throw invalid_argument if out of range. @return the correct Month. 10 11 */ Month toMonth(int mm) { 12 13 14 15 16 17 } Demo.cpp 1 #include 2 #include 3 #include "date.h" 4 using namespace std; 5 6 int main() 7 { cout « "Enter date as mm/dd/yyyy: "; int mm, dd, yyyy; char slash; cin >> mm >> slash » dd >> slash » yyyy; 8 10 11 12 13 try { Date d = makeDate (toMonth(mm), dd, yyyy); cout <« "The date is " << d << endl; } catch (invalid_argument& e) { cout « e.what() « endl; } 14 15 16 17 18 19 20 21 22 }
