Problem running the serial module with Python

Question

I am trying to use the serial port on the Raspberry but when I run the example below I have the message:

TypeError: 'module' object is not callable

import time
import serial
ser = serial.serial(
 port='/dev/ttyUSB0',
 baudrate = 9600,
 parity=0,
 stopbits=1,
 bytesize=8,
 timeout=1
)
while 1:
 ser.write('A')
 x=ser.readline()
 print (x)
 time.sleep(1)

• tlfong01: Hi @Wagner Ideali, Welcome. Ah let me see. Your edited program does not seem to match the earlier error message, therefore should mislead future readers. Anyway, I tried tracin back the original picture and reproduce your situation, but failed: imgur.com/gallery/1Rh4vVk.
• tlfong01: Your original version seems to have a syntax/typo error of "serial.serial(...)" which should read "serial.Serial(...)". So I tried to run your version 1 and got the same error as yours. So far so good. Now your version 2 have a new error. I guess it is the serial/.write and serial readline error. Anyway I have summarized version 1 and version 2 results in the following penzu link:penzu.com/p/350d51c9. If you can confirm I have understood your question correctly, then I would move on to compile my answer. Cheers..
