How to validate .wp files in Python

Python 
def is_wp(file_path: str) -> bool:
    """Check if file is a valid WP by magic bytes."""
    signature = bytes([0xFF, 0x57, 0x50, 0x43])
    with open(file_path, "rb") as f:
        return f.read(4) == signature

How to validate .wp files in Node.js

Node.js 
function isWP(buffer: Buffer): boolean {
  const signature = Buffer.from([0xFF, 0x57, 0x50, 0x43]);
  return buffer.subarray(0, 4).equals(signature);
}

How to validate .wp files in Go

Go 
func IsWP(data []byte) bool {
    signature := []byte{0xFF, 0x57, 0x50, 0x43}
    if len(data) < 4 {
        return false
    }
    return bytes.Equal(data[:4], signature)
}
