import gzip, binascii, struct, numpy
import matplotlib.pyplot as plt
with gzip.open(test_data_filename) as f:
# Print the header fields.
for field in ['magic number', 'image count', 'rows', 'columns']:
# struct.unpack reads the binary data provided by f.read.
# The format string '>i' decodes a big-endian integer, which
# is the encoding of the data.
print(field, struct.unpack('>i', f.read(4))[0])
# Read the first 28x28 set of pixel values.
# Each pixel is one byte, [0, 255], a uint8.
buf = f.read(28 * 28)
image = numpy.frombuffer(buf, dtype=numpy.uint8)
# Print the first few values of image.
print('First 10 pixels:', image[:10])
