I'm new of python adn I'm using it only to complete some experiments.
I'm reading a series of data from various sensors and in the meantime
I'm writing datas on a file. I would like to print output in realtime
(or refresh it when I need) but the problem is that I'm writing on a
file every x seconds (my timestep).
Anyway from the moment that datas are scientific value is it correct to
write on a file using str(temp) and separating with ","?
I need a csv file to read it with some data analysis softwares.
...
now = datetime.datetime.now()
dayexperiment = str(now.day)+str(now.month)+str(now.year)
myfilename ="myData"+dayexperiment+".dat"
index = 0
count = 1
timestep = 10
with open(myfilename,'w') as f:
f.write('#Index Time Value')
while True:
reading = ...
...
temp=...
print 'Temp{0:0.3F}*C'.format(temp)
now = datetime.datetime.now()
file.write('\n'+str(index))
f.write(str(index)+','+str(now.hour)+':'+str(now.minute)+', '+str(temp))
index +=1
time.sleep(timestep)
