Hi! all
1: Is there a way to simplify the "write_chronodot(s,m,h)", like using a list [ ] instead ?
2: Is there a way to write like in VB, all in one line :
sec=1 : min=2 : hour=3 : write_chronodot(sec,min,hour)

Here's what I have that run OK :

def write_chronodot(s,m,h):
    data=[s,m,h]
    i2c_bus.write_i2c_block_data(0x68,0x00,data)       # write 3 chronodot registers (sec-min-hour)
    print ("1= ",data[0])
    print ("2= ",data[1])
    print ("3= ",data[2])
    return

def read_chronodot():
    chronodot=i2c_bus.read_i2c_block_data(0x68,0x00,3)
    print ("11= ",chronodot[0])
    print ("12= ",chronodot[1])
    print ("13= ",chronodot[2])
    return chronodot

sec=1
min=2
hour=3
write_chronodot(sec,min,hour)  # to set time

time.sleep(1)                                 # Wait for the chronodot to change the "sec" register

a=read_chronodot()
print (" sec= ",a[0])                        # To verify the time
print (" min= ",a[1])
print ("hour= ",a[2])

give:
1= 1
2= 2
3= 3
11= 2 # one sec more = OK
12= 2
13= 3
sec= 2 # one sec more = OK
min= 2
hour= 3

Thanks

1- what do you mean by simplify? reducing lines of code which of course reduces the readability of the code.

eg- with use of list

def write_chronodot(data):
    i2c_bus.write_i2c_block_data(0x68,0x00,data)       # write 3 chronodot registers (sec-min-hour)
    print (f"1= {data[0]} \n2= {data[1]} \n3= {data[2]}")  # these are fstrings will only work with python 3.6
    return
data =[1,2,3]   # list[sec,min,hour]
write_chronodot(data)

2- declaring multiple variables in one line.
you can use list else you can do this.

sec,min,hour = 1,2,3 # sec = 1, min = 2, hour = 3
