Question

Can someone please help convert the following C++ method into Python?

//Method to be called when program runs to read files one by one and add to inverted index

void getFilesToBeRead() {

   string str;

   ifstream in("File.txt");

   while (getline(in, str)) {

       ifstream file(str);

       string word;

       int position{ 0 };

       char c;

       int wordCount = 0;

       while (file.get(c)) { // loop to get characters one by one

           if ((c > 64 && c < 91) || (c > 96 && c < 123)||(c > 47 && c < 58)) {//ascii values used to ignore punctuation marks in text input

               word += tolower(c);

           }

           else {

               ++position;

               addWordToIndex(word, str, position);

               word = "";//re-initializing to empty string to get next word

           }

       }

       position = 0;//re-initializing to get positions from next document

   }

}

Explanation / Answer

#!/usr/bin/python

def getFilesToBeRead():

str=""

fo = open("File.txt","r")

while(str in fo):

str=fo.read(20)

word=""

position=0

c=''

wordCount=0

while(c=fo.read(1)):

c=ord(fo.read(1))

if ((c > 64 and c < 91) or (c > 96 and c < 123) or (c > 47 and c < 58)): #ascii values used to ignore punctuation marks in text input

word += c.lower()

  

else:

position=position+1

addWordToIndex(word, str, position)

word = "" #re-initializing to empty string to get next word

return
