将数据保存在列 Python DS18B20

Question

My Python code for data saves data of a temperature sensor(DS18B20) but doesn't save the Temperature in a column. The Temperature is written in a line like that: ['25.25']. Can somebody please tell me how to fix it. I have to separate the read Temperature from the Sensor into several Numbers. Thanks for your help

    while programmStatus == 1:
    #while True:
            now = datetime.now(timezoneBerlin)
                
#while True:
    # open new file
            with open ( 'test.tsv', 'w') as f:
                for temperature_single in Temperature:
                    f.write ("{:>5}\n".format('Temperature'))    
                    f.write("\t{:>5}\n".format 
                    (format(temperature_single)))
                    f.write("\n")
                    f.flush()
                    f.close()
   
                x = 0
                ds1820readout()
                print ("Sensorname und Temperaturevalue:")
                while x < tempSensorQuantity:
                    print (tempSensorName[x] , " " , tempSensorValue[x], " °C")
                    x = x + 1
print ("\n")

In this code, there is an I/0 error on closed file, can somebody please help?

It seems that Temperature is a list of values. If you try to put them into the csv you have to iterate over the list first, eg:

tempSensorName = []
tempSensorQuantity = 0 
tempSensorValue = [] 
programmStatus = 1
Temperature = tempSensorValue   

def ds1820einlesen():
    global tempSensorName, tempSensorQuantity, programmStatus 
def ds1820auslesen():
    global tempSensorName, tempSensorQuantity, tempSensorValue,              
            with open ( 'test.tsv', 'w') as f:
                for temperature_single in Temperature:
                    f.write ("{:>5}\n".format('Temperature'))    
                    f.write("\t{:>5}\n".format(format(temperature_single)))
                    f.write("\n")
                    f.flush()
                    f.close()
    
                    x = 0
                    ds1820auslesen()
                    print ("Sensorname and Temperaturevalue:")
                    while x < tempSensorQuantity:
                        print (tempSensorName[x] , " " ,
    tempSensorValue[x], " °C")
                            x = x + 1
    print ("\n")
