How to validate .msv files in Python

Python 
def is_msv(file_path: str) -> bool:
    """Check if file is a valid MSV by magic bytes."""
    signature = bytes([0x4D, 0x53, 0x5F, 0x56, 0x4F, 0x49, 0x43, 0x45])
    with open(file_path, "rb") as f:
        return f.read(8) == signature

How to validate .msv files in Node.js

Node.js 
function isMSV(buffer: Buffer): boolean {
  const signature = Buffer.from([0x4D, 0x53, 0x5F, 0x56, 0x4F, 0x49, 0x43, 0x45]);
  return buffer.subarray(0, 8).equals(signature);
}

How to validate .msv files in Go
