Hi Bradley, Thank you for your question. Would you please post questions about product usage, such as this one, in the CPLEX forum at https://www.ibm.com/develop... ? Thanks! Stephanie

Hi, I am using the docplex in python. I have an logic expression which is: T[i][j] = T[i][j] or ( T[i][k] and T[k][j] ) and the python code is:
"logical_or ( T[i][j], logical_and( T[i][k], T[k][j] )",
T[i][j] are binary variables. But my jupter notebook reminds me that: "Model.logical_and: Expecting an iterable returning variables, 0 was passed at position 0"?
So, how to code this in python? thanks.
Bradley
