Question

Context:

• I am using python 2.6.5

Goal:

• Read a binary image file and represent it in-memory. Then run a checksum on it. Deliver the binary representation to be stored as a blob in mysql.

Comments:

• I have read this SO thread.
• I have looked at the struct module.
• I also have bumped into the io module.
• With all the available options, I am not certain which is the best solution. The BytesIO data structure seems to be suitable for my needs. Which one do you think will meet my requirements ?

Answer 1

>>> from binascii import crc32
>>> with open(filename, "rb") as f:
...     data = f.read()
...
>>> crc32(data)
