How to validate .minipsf files in Python

Python 
def is_minipsf(file_path: str) -> bool:
    """Check if file is a valid MINIPSF by magic bytes."""
    signature = bytes([0x50, 0x53, 0x46])
    with open(file_path, "rb") as f:
        return f.read(3) == signature

How to validate .minipsf files in Node.js

Node.js 
function isMINIPSF(buffer: Buffer): boolean {
  const signature = Buffer.from([0x50, 0x53, 0x46]);
  return buffer.subarray(0, 3).equals(signature);
}

How to validate .minipsf files in Go

Go 
func IsMINIPSF(data []byte) bool {
    signature := []byte{0x50, 0x53, 0x46}
    if len(data) < 3 {
        return false
    }
    return bytes.Equal(data[:3], signature)
}
