Python reads serial output from arduino

I have an Arduino connected with 2 DS18B20 temperature sensors. I am very (VERY) new to python. I am looking for a way to read sequential input and parse it in a sqlite database, but this is ahead of me. Why am I getting an error when trying to determine my serial port for a variable?

First things first sys.version

 2.7.1 (r271:86832, Jul 31 2011, 19:30:53) [GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)]

My current one, just read the input from the serial connection program.

 from serial import serial import time # open serial port ser = serial.Serial('/dev/tty.usbmodem621',9600,timeout=2) ser.open() while True: print('dev 0' + ser.read()) pass ser.close()

Currently, I cannot compile it. Most of the results that I found for this error say to add from serial import serial , but in this case it did not work.

Error.

 $ python ser.py Traceback (most recent call last): File "ser.py", line 1, in <module> from serial import serial File "/Users/frankwiebenga/serial.py", line 8, in <module> AttributeError: 'module' object has no attribute 'Serial'

Also, if I just use import serial , I get the same error

 $ python ser.py Traceback (most recent call last): File "ser.py", line 1, in <module> import serial File "/Users/frankwiebenga/serial.py", line 8, in <module> AttributeError: 'module' object has no attribute 'Serial'

Also for the comment. Created a new file called something.py and still got the same error, regardless of using import serial or from serial import serial .

 $ python something.py Traceback (most recent call last): File "something.py", line 1, in <module> from serial import serial ImportError: No module named serial

When I run my bash script, I get output that is valid, so I know that this is not Arduino code.

Output:

 Requesting temperatures...DONE Device 0: 25.62 Device 1: 25.75 Requesting temperatures...DONE Device 0: 25.62 Device 1: 25.81

Bash:

 while true # loop forever do inputline="" # clear input # Loop until we get a valid reading from AVR until inputline=$(echo $inputline | grep -e "^temp: ") do inputline=$(head -n 1 < /dev/tty.usbmodem621) done echo "$inputline" done

You need to use import serial . serial is the name of the module and does not contain an attribute named serial .

You can:

 from serial import Serial s = Serial(...)

OR

 import serial s = serial.Serial(...)

Choose one.
