Write a program that reads two input files whose lines are ordered by a key data field. Your program should merge these two files, writing an output file that contains all lines from both files ordered by the same key field. As an example, if two input files contain student names and grades for a particular class ordered by name (the key field), merge the information as shown below. File 1 and file 2 are supplied. Here is an algorithm to merge the data from two files: Read a line from each data file While the end of both files has not been reached While the end of both files has not been reached Write the line from file 1 to the output file and read a new line from file 1. Else Write the line from file 2 to the output file and read a new line from file 2. Write the remaining lines (if any) from file 1 to the output file. Write the remaining lines (if any) from file 2 to the output file. See the Merging Filesslides attachedto the project in Canvasfor a visual look at this algorithm.

i  have already asked this question and the answer did not work for me:   Write a program that first reads in the name of an input file and then reads the file using the csv.reader() method. The file contains a list of words separated by commas. Your program should output the words and their frequencies (the number of times each word appears in the file) without any duplicates. Ex: If the input is: input1.csv and the contents of input1.csv are: hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy the output is: hello 1 cat 2 man 2 hey 2 dog 2 boy 2 Hello 1 woman 1 Cat 1 Note: There is a newline at the end of the output, and input1.csv is available to download.

Task. Your task is to develop a python program that reads input from text file and finds if the alphanumeric sequence in each line of the provided input file is valid for Omani car license plate. The rules for valid sequences for car plates in Oman are as follows: Each sequence is composed of 1 to 5 digits followed by one or two letters. Digits cannot start with 0, for instance, 00, 011, or 09 are not valid digit sequences. The following list are the only valid letter combinations: ['A','AA','AB','AD','AR','AM','AW','AY', 'B','BA','BB','BD','BR','BM','BW','BY', 'D',DA','DD','DR','DW','DY', "R',RA','RR','RM','RW','RY', 'S','SS', 'M', 'MA','MB','MM','MW','MY', W',WA','WB','ww, Y,YA','YB','YD','YR','YW','YY'] Program Input/Output. Your program should read input from a file named plates.txt and write lines with valid sequences to a file named valid.txt. Any line from the input file containing invalid sequence should be written to a file named invalid.txt. Each line from the input file must…
