To open a file in Python and read its contents in bytes, you can use the following code:
```python
with open("myfile", "rb") as f:
while (byte := f.read(1)):
# Do something with each byte
```
Here's a breakdown of the code:
1. `open("myfile", "rb")`: Opens the file named "myfile" in binary mode ("rb").
2. `with ... as f`: Ensures proper handling of resources.
3. `while (byte := f.read(1)):`: Reads the file one byte at a time and iterates through each byte.
4. Inside the loop, you can perform operations on each byte.
This approach ensures efficient handling of binary files[1][2][3].
