Syntax for if clause with an inline variable in modelbuilder

Question

In the "Calculate Value" tool I am trying to slice the inline variable (%Name%) with another variable (A) that will be a result of the length of the %Name% variable. For example if %Name% = 11 then I would like A = 8, else I would like A = 9.

"%Name%"[:A]

• What should be the syntax of the expression and the code block? enter image description here

Answer 1

Calculate Value Documentation

Expression:

fn("%Name%")

Code Block:

def fn(name):
 if len(name) is 11:
 A = 8
 else:
 A = 9
 return name[:A]

enter image description here

• Paul: here is an example (with completely incorrect syntax) on what I am trying to do: if len(%Name%) = 11 then %A% = 8 else %A% = 9 end if
• Squanchy: Updated answer. Does this answer your question? You want to slice the input string based on its length?
