Hello, I would like the following code translated to python as I think it pertains to the HW assignment linked below. Thanks!

import java.lang.*; import java.util.StringTokenizer; import java.io.*; public class Parse { public static final String[] errMsg = { "ERROR -- Invalid Method token.", "ERROR -- Invalid Absolute-Path token.", "ERROR -- Invalid HTTP-Version token.", "ERROR -- Spurious token before CRLF." }; public static boolean methodChecking(String token, String method){ if(token.equals(method)) //Checking with designated method return true; return false; } public static boolean pathChecking(String token){ //Check if path is valid if(token == null) return false; if(token.charAt(0) != '/') return false; if(token.length() == 1) return true; //Checking if the first character is '/' for(int i = 1; i < token.length(); i++){ char tmp = token.charAt(i); if(Character.isLetterOrDigit(tmp) || tmp == '.' || tmp == '_' || tmp == '/') continue; return false; } //Checking the rest characters return true; } public static boolean versionChecking(String token, String protocol){ if(token.length() < protocol.length() + 4) return false; //At least 4 additional characters "/?.?" are needed String headOfVersion = token.substring(0, protocol.length() + 1); if(!headOfVersion.equals(protocol + "/")) return false; //Checking the header of Version if(!Character.isDigit(token.charAt(protocol.length() + 1))) return false; //the character immediate after '/' must be a digit boolean dotHit = false; //flag of the '.', which occurs exactly once for(int i = protocol.length() + 2; i < token.length() - 1; i++){ if(!Character.isDigit(token.charAt(i))){ if(dotHit) return false; //More than one dot if(token.charAt(i) == '.'){ dotHit = true; //first dot is encountered. continue; } return false; } } if(dotHit && Character.isDigit(token.charAt(token.length()-1))) return true; //Exactly one dot and the last character is a digit else return false; } public static void main(String[] args) throws IOException{ String inputLine; String[] tokensTank = new String[3]; //storage of tokens BufferedReader standardIn = new BufferedReader(new InputStreamReader(System.in)); inputLine = standardIn.readLine(); StringTokenizer inputTokens = new StringTokenizer(inputLine); //standard inputing System.out.println(inputLine); if(inputLine.length()>=1){ if(Character.isWhitespace(inputLine.charAt(0))){ System.out.println(errMsg[0]); return; } } if(inputTokens.hasMoreTokens()){ tokensTank[0] = inputTokens.nextToken(); if(!methodChecking(tokensTank[0], "GET")){ System.out.println(errMsg[0]); return; } } else{ System.out.println(errMsg[0]); //Missing return; } //The above code is checking the first token if(inputTokens.hasMoreTokens()){ tokensTank[1] = inputTokens.nextToken(); if(!pathChecking(tokensTank[1])){ System.out.println(errMsg[1]); return; } } else{ System.out.println(errMsg[1]); return; } //The above code is checking the 2nd token if(inputTokens.hasMoreTokens()){ tokensTank[2] = inputTokens.nextToken(); if(!versionChecking(tokensTank[2], "HTTP")){ System.out.println(errMsg[2]); return; } } else{ System.out.println(errMsg[2]); return; } //The above code is checking the 3rd token if(inputTokens.hasMoreTokens()){ System.out.println(errMsg[3]); return; } //The above code is checking if there is spurious token System.out.println("Method = " + tokensTank[0]); System.out.println("Request-URL = " + tokensTank[1]); System.out.println("HTTP-Version = " + tokensTank[2]); } }
