Python에서 바이너리 파일을 바이트 단위로 효율적으로 읽으려면 어떻게 해야 합니까?

with open("myfile", "rb") as f:
    while (byte := f.read(1)):
        # Perform operations on the byte

with open("myfile", "rb") as f:
    byte = f.read(1)
    while byte != b"":
        # Perform operations on the byte
        byte = f.read(1)

with open("myfile", "rb") as f:
    byte = f.read(1)
    while byte:
        # Perform operations on the byte
        byte = f.read(1)

with open("myfile", "rb") as f:
    byte = f.read(1)
    while byte != "":
        # Perform operations on the byte
        byte = f.read(1)

f = open("myfile", "rb")
try:
    byte = f.read(1)
    while byte != "":
        # Perform operations on the byte
        byte = f.read(1)
finally:
    f.close()
