Utility function getting too long

Is there an example of where I can write an extremely long utility function, but break it up into parts so I do not get into parsing restrictions?

Thank you in advance for any examples!

Hi Tom,

In Python, you can write a long expression on several lines by placing it into parentheses:

V = (

beta_1 * x_1 +

beta_2 * x_2 +

…

)

Also, I would recommend to use loops as much as possible instead of very long expressions.

Finally, if you have a long sum, prefer the bioMultSum operator to a long list of binary “+”.

Thank you. I'll study up on bioMultSum
