I need help creating a program that searches through a text file and returns the line number and colum the perticular word inputed is found. $ Search Ring Tolkien1'Ring' found at:line 1, column 7line 6, column 5line 6, column 32line 7, column 5$ Search 'nd t' Tolkien1'nd t' found at:line 6, column 42line 7, column 50$ Search ';' Tolkien2';' found at:line 2, column 26line 8, column 5$ Search Ring Tolkien2'Ring' not found$ Search RingUsage: Search $ SearchUsage: Search $As always, your output must match the above format exactly for full credit. Observe that if the user doesnot have exactly two command line arguments after the Search command, a usage message will be printed.The basic algorithm for this program will be to get each line of , and search for all occurrences ofthe substring within that line. When you find a match, save the line number and the position inthe line at which the substring begins. When all lines have been searched, print out your match positionsin the proper format, or print a message stating that the substring was not found. Note that when countinglines and columns, your counts must begin at 1, not at 0. See the following examples to learn differentways to iterate over the lines in a file./Examples/Filel.py/Examples/File2.py/Examples/File3.py/Examples/File4.py/Examples/pa6/FileCopy.pyAlso, see the documentation of function str.find() athttps://docs.python.org/3.9/library/stdtypes.html#text-sequence-type-strto learn how to search a single line for a substring. Follow the general template posted in /Examples whenwriting this program. As always start early and ask for help if anything is not fully clear. Submit your file In this project you will write yet another Python script to be run on the Unix timeshare, called search.This program will emulate the most elementary functionality of the grep command in Unix. The command$ grep where is a string and is a text file in your current working directory, prints all lines infile that contain the substring . Depending on your terminal settings, it may alsohighlight the occurrences of in a different color. Download the files Tolkien1 and Tolkien2from / Examples/lab5, and place them in a convenient directory on the timeshare (like ~/cse20/lab5).From within that directory, type$ grep Ring Tolkien1and observe that all lines containing instances of the string 'Ring' are printed. Notice that there are 4instances, and one instance is within the word "Rings". Thus, we see that grep is finding substrings ofeach line, considered as a large string. You can also search for strings that contain spaces, as long as youenclose that string in quotes (which you may do in any case.) Try doing$ grep 'nd t' Tolkien1to find two instances. Any string that contains characters having a special meaning to the bash interpreter,such as the space, must be enclosed in quotes. For instance, if you search for a semi-colon ; by doing$ grep ; Tolkien2the interpreter thinks you are running two commands: grep (which gives you a usage message because yougave it no arguments), followed by Tolkien2 (which gives a warning because the file is not executable).On the other hand$ grep ';' Tolkien2sucsessfully locates two occurrences of ; within Tolkien2.The command grep stands for: Globally search for a REgular expression and Print matching lines. Aregular expression, or regex, is a sequence of characters that specifies a search pattern. The simplestpossible such pattern is just a string to be searched for and matched, as demonstrated in the above examples.More complex regular expressions can be used by grep to match sets of strings rather than just a singlestring. We will not cover more advanced regular expressions here. Your Search program will emulatethe functionality of the grep on these elementary examples. Google the term regular expression to learnmore about this important concept,do man grep to learn more about the functionality of the grepcommand.The output of Search will differ from that of grep in an essential way however. Instead of printing outthe lines with matching occurrences of , Search will state the line number and column numberof (the beginning of) each occurrence of within . We illustrate the operation of Searchbelow on all of the preceding examples, and a few more.
