How To Deal With Indentationerror: Unexpected Indent

I'm currently working with raspberry pi and using DHT11 to read temperature and humidity values every second. I have to save these values into a database in real time. Here's my co

Solution 1:

you had indent error in try except, both should be at same indent

Inshort it should be like:

imports.....
.
.
.
withopen('test.csv', 'w', newline='') as csvfile:
    .
    .
    .
    try:
        .
        .
    except:
    .
    .
