Learning Goal: I’m working on a python question and need an explanation and answer to help me learn.Write a program that will take an input file called input.txt which will contain a Java program and parse it and output an annotated version.Your program will track the nesting depth of the braces of the input file and will output an annotated version of the file. Your final program will:1. List the nesting depth of curly braces2. Ignore braces inside quotes or comments3. Test for unmatched braces (expected ‘}’ but found EOF); output an error message4. Allow for multiple braces on the same line, for example “}}” ending a loop and a function5. Handle block comments that cross multiple lines of the input file.example: /* comment with ignored brace { */
