I have configured on Raspberry Pi UART and this is my serial reading / writing code:
ser = serial.Serial('/dev/ttyAMA0', 9600, timeout=1)
ser.open()
string = '#SET0\r\n'
print string
ser.write(string)
bytes2read = ser.inWaiting()
print bytes2read
if (ser.inWaiting()>0):
incoming = ser.readline()
print incoming
time.sleep(5)
bytes2read1= ser.inWaiting()
print bytes2read1
if (ser.inWaiting()>0):
print "Data:"
cont = ser.read(bytesaleer1)
print cont
cont has this format:
#D0:0:0:10
#D1:0:0:56
#D2:0:0:23
#D3:1:1:90
--------
My question is, How can I get and save the last 0 on that variable? I want to save in c0,c1,c2,c3 values obtained from cont; 10,56,23 and 90. Have tried with line.strip but with no good results.
If cont is a string containing all five lines of text, including the -------- separator line, I'd start by splitting it into lines:
cont.splitlines()
=> [ '#D0:0:0:10',
'#D1:0:0:56',
'#D2:0:0:23',
'#D3:1:1:90',
'--------' ]
Then you can loop over all the lines, and if the line includes a colon, pull off the last value and save it.
vals = []
for line in cont.splitlines():
if ':' in line:
v = int(line.split(':')[-1])
vals.append(v)
>>> vals
[10, 56, 23, 90]
