I"m trying to use pyserial. When I do the following script.

import serial
ser= serial.serial("COM5", 9600)
ser.write("Hello worldn")
x = ser.readline()
print(x)

Error code:

c:\Python27>python com.py
Traceback (most recent call last):
  File "com.py", line 2, in <module>
    ser= serial.serial("COM5", 9600)
AttributeError: 'module' object has no attribute 'serial'

I read a suggestion and changed it to:

from serial import serial
ser= serial.serial("COM5", 9600)
ser.write("Hello worldn
x = ser.readline()
print(x)

I now get the error

c:\Python27>python com.py
Traceback (most recent call last):
  File "com.py", line 1, in <module>
    from serial import serial
ImportError: cannot import name serial

I read that this can be from having ini in your module, but dont' know anyting about this.

I printed my sys.path and pyserial is in there.

The error you are getting means your interpreter cannot locate the serial module. Have you installed it? Are you sure you have proper permissions to use it? — Michael F

Did you happen to call one of your programs serial.py? At the start of your code, add import serial and print(serial.__file__) as the first two lines. — DSM

I did name it serial.py initially, but changed it. Here is the output of the print. c:\Python27\lib\site-packages\pyserial-2.7-py2.7.egg\serial_init_.pyc — jeffpkamp

I'll second that. DONT NAME YOUR FILE SERIAL.PY. sorry for all caps but I've been burned by this twice in two years, and I missed this comment in this file both times. Thanks :) — benathon

It should be:

import serial
ser = serial.Serial("COM5", 9600)

Note the capital 'S' in serial.Serial

That appears to be it! At least the error went away, I'll have to wait until I"m home to be sure it's actually talking to the port. Dang capitalization and indentation get me every time :). Thanks
