performance - Random-access container for strings in python? -

-

i manipulate indexed instances (say, music tracks) , have lookup object's name index (int->string). dicts slow (i have 10m objects). memory not problem, convinient solution create random-access array of strings csv file names.

however, have failed make in python -- got error 0-dim arrays (strings) couldn't indexed. what's native python way create random access container strings?

from remember, dictionaries in python have o(1) average access time, lists faster. if indices not sparse, can try this:

reader = [(1, 'a'), (2, 'b')] # replace csv reader.  # first, fill dictionary: text_dict = {} index, text in reader:     text_dict[index] = text  # create sufficiently large list: max_index = max(text_dict.iterkeys()) texts = [none] * (max_index + 1)  # , fill it: index, text in text_dict.iteritems():     texts[index] = text  print texts # prints: [none, 'a', 'b'] print texts[1] # prints:

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
