using input as both an array and a string

Question

I feel like there is a simple solution to this but I am kinda new.

stat_input= input("Hello Mr. Jenner, what are you interested in tracking today?")

I use an input like this which later is used to call upon data and uses that data to calculate statistics and produce histogram charts / normal distributions.

It works quite nicely. Here are some examples where it is used.

cur.execute('SELECT {} FROM statdata'.format(stat_input))
np.array(stat_input).astype(np.float)

sigma = math.sqrt(np.var(stat_input))

So if I type threemonthdata it will pull the array of data from my database and use it . Its great. However, I have one small problem

I understand that threemonthdata refers to an array. Since I am creating charts, I want to use the input as the title so the chart title identifies what data I am drawing and using (as a reference in the future)

ax.set_title('stat_input')

This doesn't work

ax.set_title(' + stat_input + ')

Nor does this. I want the title to say Threemonthdata. But if I input twomonthdata I want it to say twomonthdata and not give me the array of numbers.

Any ideas?

I have never played with psycopg's cursor class. But, from what I can read, it appears that this one does the job for you of turning your string in place into a list whose name is the same as the referring string.

Thus what about defining another viariable to store the string before it is overriden ? As follows

stat_input_title = stat_input.capitalize()
cur.execute('SELECT {} FROM statdata'.format(stat_input))

Henceforth, stat_input_title and stat_input can be used together withouh conflicting.

ax.set_title(stat_input_title)

It looks like the issue you are facing is that you are passing the set_title() a string 'stat_input', and not the variable stat_input. You likely simply need to use:

ax.set_title(stat_input)

You are right, but how could math.sqrt(np.var(stat_input)) works in this case ? stat_input is an array since the OP says : "I want the title [...] not give me the array of numbers." Also, it appears that the OP thinks that by doing 'stat_input', he will get as string the original name of the numpy array. Actually, as if he were coding in stata, handling local macros.
