We have omitted the except and finally blocks since they are the same as the ones shown in the preceding subsection, apart from the particular exceptions that the except block catches We begin by opening the le in write binary mode, either a normal le or a gzip compressed le depending on the compress ag We then write the 4-byte magic number that is (hopefully) unique to our program, and the 2-byte version number Using a version number makes it easier to change the format in the future when we read the version number we can use it to determine which code to use for reading Next we iterate over all the incidents, and for each one we create a bytearray We add each item of data to the byte array, starting with the variable length strings The datetoordinal() method returns a single integer representing the stored date; the date can be restored by passing this integer to the datetimedatefromordinal() method The NumbersStruct is de ned earlier in the program with this statement:

NumbersStruct = structStruct("<Idi ")

This format speci es little-endian byte order, an unsigned 32-bit integer (for the date ordinal), a 64-bit oat (for the percentage hours on type), a 32-bit integer (for the total hours own), and a Boolean (for whether the incident was midair) The structure of an entire aircraft incident record is shown schematically in Figure 73 Once the bytearray has all the data for one incident, we write it to disk And once all the incidents have been written we return True (assuming no error occurred) The finally block ensures that the le is closed just before we return Reading back the data is not as straightforward as writing it for one thing we have more error checking to do Also, reading back variable length strings is slightly tricky Here is the start of the import_binary() method and the complete nested unpack_string() function that we use to read back the variable length strings:

There is no central repository for magic numbers like there is for domain names, so we can never guarantee uniqueness

Since each incident record begins with its report ID string, when we attempt to read this string and we succeed, we are at the start of a new record But if we fail, we ve reached the end of the le and can nish We set the eof_is_error ag to False when attempting to read a report ID since if there is no data, it just means we have nished For all other strings we accept the default of True because if any other string has no data, it is an error (Even an empty string will be preceded by a 16-bit unsigned integer length) We begin by attempting to read the string s length If this fails we return None to signify end of le (if we are attempting to read a new incident), or we raise a ValueError exception to indicate corrupt or missing data The structunpack() function and the structStructunpack() method always return a tuple, even if it contains only a single value We unpack the length data and store the number it represents in the length variable Now we know how many bytes we

must read to get the string If the length is zero we simply return an empty string Otherwise, we attempt to read the speci ed number of bytes If we don t get any data or if the data is not the size we expected (ie, it is too little), we raise a ValueError exception If we have the right number of bytes we create a suitable format string for the

the data and decoding the bytes as UTF-8 (In theory, we could replace the last two lines with return datadecode("utf8"), but we prefer to go through the unpacking process since it is possible though unlikely that the s format performs some transformation on our data which must be reversed when reading back) We will now look at the rest of the import_binary() method, breaking it into two parts for ease of explanation
