Nested for loops - help with iterating a variable outside of the main loop

[dm222]

Try posting your questions one at a time. I have no idea how to answer everything you've asked so far. I don't really understand what you are asking half the time.

Starting with you last edit. Python thinks ax[index] is indexing a value in a list or array and ax(index) is a function call.

This is where Python sees the error:

Error:
---> 10                         m = p(ax(p), ax(q))

And this is what Python thinks the error is:

Error:
TypeError: 'numpy.ndarray' object is not callable

For indexing use [], not ().


In your first attempt at plotting you got an error because you called the plot function with an invalid argument.
This is where Python sees the error:

Error:
---> 11                 ax[row, col].plot(x, y, color="green", fontsize=18, ha='center')

And this is what Python thinks the error is:

Error:
AttributeError: 'Line2D' object has no property 'fontsize'

If you look at the documentation you would see that it does't have a fontsize argument.

Thank you, firstly, I've made the question far more concise. I appreciate your advice on that. Hopefully my questions are clearer now.

Regarding your first point, I've change from () to []:

def plot_global_inf_sub():
        n = len(df_transposed.columns)
        x = years
        p = 1
        i = 0
        for c in df_transposed.loc['Aruba':'Zimbabwe']:
            for p in range(n):
                for q in range(n): 
                    if i <= n:
                        m = p(ax[p], ax[q])
                        fig, m = plt.subplots(int(n/2), int(n/2))
                        a = 1
                        y = df_transposed[c]
                        ax[i,(i-i)].plot(x, y)
                        ax[i, a(i=+1)].plot(x, y)
                        plt.show()
        
plot_global_inf_sub()

And now get the following error:

Error:

     12                         a = 1

TypeError: 'int' object is not callable

It's good for me to read and understand your error/explanation reply, thank you.
