How to validate .tbz files in Python

Python 
def is_tbz(file_path: str) -> bool:
    """Check if file is a valid TBZ by magic bytes."""
    signature = bytes([0x42, 0x5A, 0x30])
    with open(file_path, "rb") as f:
        return f.read(3) == signature

How to validate .tbz files in Node.js

Node.js 
function isTBZ(buffer: Buffer): boolean {
  const signature = Buffer.from([0x42, 0x5A, 0x30]);
  return buffer.subarray(0, 3).equals(signature);
}

How to validate .tbz files in Go

Go 
func IsTBZ(data []byte) bool {
    signature := []byte{0x42, 0x5A, 0x30}
    if len(data) < 3 {
        return false
    }
    return bytes.Equal(data[:3], signature)
}
