(While Running Multiple Containers)
Setting "stdin_open:true" to your react instance
react:
stdin_open: true //NOTE:
build: dockerreact
ports: - "3000:3000"
#Change to: open(filename).read()
with open('/path/to/some/file', 'r') as fp:
hex_list = ["{:02x}".format(ord(c)) for c in fp.read()]
Or, if you do not want to keep the whole list in memory at once for large files.
hex_list = ("{:02x}".format(ord(c)) for c in fp.read())
and to get the values, keep calling
next(hex_list)
to get all the remaining values from the generator
list(hex_list)
