How to validate .dpx files in Python

Python
def is_dpx(file_path: str) -> bool:
    """Check if file is a valid DPX by magic bytes."""
    signature = bytes([0x53, 0x44, 0x50, 0x58])
    with open(file_path, "rb") as f:
        return f.read(4) == signature

How to validate .dpx files in Node.js

Node.js
function isDPX(buffer: Buffer): boolean {
  const signature = Buffer.from([0x53, 0x44, 0x50, 0x58]);
  return buffer.subarray(0, 4).equals(signature);
}

How to validate .dpx files in Go

Go

    if len(data) < 4 {
        return false
