⏰Python considers empty string position
1) At the start 2) Between every character
3) At the end of a string
🤔 *No. of empty string = len(string)+1*

✓ *s = 'Dewey'*
✓ *print(s.replace('','*',3))*
→'' occurs at 6 positions 🤔, c is 3→Inserts 3 '*'
→⏰ *At start→Between 'D' and 'e'→Between 'e' and 'w'*
⇒ '*D*e*wey'
💁🏻∴ Prints⇒ **D*e*wey*

💁🏻‍♀️ *print(s.replace('','*'))⇒ *D*e*w*e*y**
