In python you can use strings with the or and and keywords. The program sends a TCP request and prints the response, but if it fails it prints connection error.

def Send_TCP_Request():
  try:
    tcpc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    tcpc.settimeout(1)
    tcpc.connect(('0.0.0.0', 8000))
    tcpc.send('Hello World')
    Result = tcpc.recv(1024)
    tcpc.close()
  except:
    Result = None

  return Result

def setup():
  M5.begin()
  print(Send_TCP_Request() or "Connection Error")

@colobro309 That isn't a bug, that's just how mathematics works.
And/or are logical functions, they only take true/false as inputs and returns a true/false.
Add/subtract are arithmetic functions, they only take numbers as inputs and returns a number.

You will need to convert your string or number into a true/false value first.
The "IF" block can do this as it returns true/false.
Eg "If number=0 return false else return true"
