![]() ![]() ![]() Since, as noted above, findall returns a list of results in order, and enumerate also operates in order, the index created by enumerate is also the chunk's relative position in the original data. Now, by putting everything together in a dict comprehension, we become more able to access the lengths of chunks by an index created by enumerate. If you apply enumerate to it, you'll get tuples (0, 5) (index 0, length 5), (1, 3) (index 1, length 3) and (2, 4) (index 2, length 4). Run :xxd -r (reverse transformation) Save. So, say you have a list, representing chunk lengths. 6 Answers Sorted by: 377 To view the file, run: xxd filename less To use Vim as a hex editor: Open the file in Vim. Further, if say there are some bytes which are having their 5 most significant bits same, while lower 3 bits vary from 000 to 111, then this also forms a pattern since 5bits are same at several places. Would be nice if you could jump to a certain address, but you can at least scroll up and down though the whole drive. And that will display stuff rather like GHex, hex values and ASCII values side by side. If we did, that would give us a list of the lengths of all chunks found, in the order they were found (this will be important later).Įnumerate is a built-in function that allows "tagging on" an index (starting from 0, by default) to some iterable object. For example, it can be any byte say 0x4a or 0x56 or any byte. Rep: Sussed it, hexedit is pretty much perfect. With the len operator, we can find the length of each chunk, and those will form the values of our dictionary. These are bytes objects, which have a well-defined length (the number of bytes in them). You originally used re.findall to get every chunk in the source data which follows your given regex. ![]()
