How can I read multiple sensor data?

Hello,

I am trying to connect a bunch of sensors to my ESP32. I want to connect it to the Blynk app in order to get some data on my phone.

I am currently coding on python, however, I have an issue.

The code seems to always stop after it reads the light sensor. Basically, I only get the data from the light sensor and it loops from there.

Any clue what is wrong with the code?

wifi.connect(WIFI_SSID, WIFI_PASS)
