Answer 1

\U is the start of an escape sequence in string litterals, as are a few others like \u , \n ...

If you want to have litteral backslashes in your string, you can either:

• Escape them:

  "C:\\Users\\BRS\\Desktop\\wattpad.txt"

• or better, use a raw string by prefixing the string with r :

  r"C:\Users\BRS\Desktop\wattpad.txt"

• or use forward slashes, even on Windows:

  "C:/Users/BRS/Desktop/wattpad.txt"
