  • How to . seek () to the end of a text file - Stack Overflow
    f seek(0) contents = f read() What happens here is that the pointer starts at the beginning of the file when you enter the with block, then the code will read the file all the way to the end, which is where the pointer remains until you exit the with block (or change it's position with seek())

  • c - behaviour of fseek and SEEK_END - Stack Overflow
    ^ This is the (0, SEEK_END) byte With this in mind, the very last byte of the file is the one found at (-1, SEEK_END) and thus the (-3, SEEK_END) byte is the 8 Note that this is consistent with how C usually handles this kind of thing For example a pointer to the end of a memory block will usually point to one-past the last byte of that block
