How to make GH python if elif else work?

hi everyone,
i want to make this GH python work properly but every results just come out 0.

these are fomulas that i want to apply on the list named list_x

thank you for any response!

your code should be working :slight_smile: (9.1 KB)

make sure you have right clicked on the “x” input of the Python component and set the input type to “float”, I see there are decimals in your data

when your code reaches your line 14 → elif (x>100 and x<300): you could remove the first test x>100 because it’s a condition already verified in line 12


thank you so much!!! it works now!!!
