Python How to Return value in while loop

Question

When put return in while loop the loop will stop How to fix it?

ser = serial.Serial(
    port=\'COM5\',
    baudrate = 9600,
    timeout=1)
while 1:
    x=str(se         


        

Answer 1

Simply take your

x=str(ser.readline())
x = re.findall("\d+\.\d+", x)
x = float(x[0])
return(x) #loop stopped

put it into a function like

def foo(ser):
    x=str(ser.readline())
    x = re.findall("\d+\.\d+", x)
    x = float(x[0])
    return(x)

and change your while loop to simply be

while 1:
    print(foo(ser))

However @developius had a better solution which would look something like

while 1:
    x=str(ser.readline())
    x = re.findall("\d+\.\d+", x)
    x = float(x[0])
    print(x)
