The given code opens a file named "VIVO.txt" in read mode and reads its entire content into a variable F1. It then calculates the length of this content using len() and prints the result, which is 30 characters long. However, when it tries to read the next 5 characters from the file using F1.read(5), no characters are left to read since the file pointer is at the end the file. As a result, data remains an empty string.
