A simple prompt to Sonnet 4.6 for a python script. What do I get?

Here’s the prompt.

“Please provide a python program to generate a time series of 30 ticks for three variables x, y, z. z is a function of x and y. x, y, and z vary within an upper and lower bound. The values of x, y, and z should be held as a float type. The time series for the three variables is output as a csv to a windows directory”

What did I get?

Result Received from Sonnet 4.6

“””

Time Series Generator for Variables x, y, z

– Generates 30 ticks of time series data

– z is a function of x and y: z = sin(x) * cos(y)

– All values are floats bounded within [lower, upper] limits

– Output written to a CSV file

Did it Run? No, there was a syntactic bug. Was this a good thing?

If work in the digital realm consists of the following processes:

Identification of imperative (ideation)

determination of response (analysis and design)

Until money, time or functionality constrain:

Build, Review, Test (in an ideal world)

Deploy

Where is Claude best deployed?

Was time saved? About a half-hour, a sixteenth of a work day. Quite a lot over a year with lots of employees. However, does repeated use of Claude not only train Claude but train the user so that over time, Claude becomes a bit of a bore, perhaps an expensive bore at that.

Hang on, what happens if Claude is the only tool available to do the job? Now that’s a different story.

No programmers in town for iterative development of prototypes for customer appraisal.

A stupendous pile of digital sludge to sort out.

A hacked body of knowledge.

Coming soon.
