abaqus scripting: TypeError: cannot concatenate 'str' and 'Set' objects

Question

I get the error

TypeError: cannot concatenate 'str' and 'Set' objects 

and the error is caused by my code

name=inst1name+'-'+setName 

I know the problem is: inst1name is a set object, however this error never come up before when I run the script.

Do you know why is this? and how can I solve it?

Answer 1

You could explicitly convert the set to its string representation like this:

name = inst1name + '-' + str(setName)

But a better way would be to use string composition like this:

name = '%s-%s' % (inst1name, setName)

Or even string.format like this:

name = '{}-{}'.format(inst1name, setName)
