Can't load binary file into Array...

[KevinJohnson]

Here's what i'm trying to do:

1. Generate a random file
2. Read that file in by n-byte chunks
3. Store each chunk in it's own Array element

error produced:
----------------------------------------------------------------------------------------------------------
SyntaxError: can't assign to function call
----------------------------------------------------------------------------------------------------------

Bits and info:
================
- i'm on python 2.7
- OS is Linux 64 bit
================

am i using the wrong kind of data structure to store the chunks of data?

here's my code:

# Split the File int an Array
def SplitFile(filename, blocksize):
    with open(filename, "rb") as f:
        i = 0
        byte = f.read(blocksize)
        while byte:
            # Put the Data Blocks into the Array Elements
            FileData.append[i] = f.read(blocksize)
            i = i + 1
        f.close()

def RandomFile(n, filename):
    filedata = ""
    for i in range(n):
        rnd = random.randint(0,255)
        filedata = filedata + chr(rnd)
    # Write the data to the disk
    f = open(filename, 'w')
    f.write(filedata)
    f.close()

blocksize = 16000
filename = 'RndFile.rnd'
FileData = []
a = RandomFile(blocksize * 8, filename)
SplitFile(filename, blocksize)
