python - Giving different titles to plots in for-loop -

this question has answer here:

• matplotlib: same title 8 plots plotted using loop 1 answer

import numpy np import matplotlib.pyplot plt  d = 12 n = np.arange(1,4) x = np.linspace(-d/2,d/2, 3000) = np.array([125,300,75]) phase = np.genfromtxt('8phases.txt')  i_phase = i*phase  count,i in enumerate(i_phase):     f = sum(m*np.cos(2*np.pi*l*x/d) m,l in zip(i,n))     f = plt.figure()     ax = plt.plot(x,f)     plt.savefig(str(count)+'.png') plt.show() 

this script generates 8 plots , saves them. want give plots different titles. possible read .txt or excel file (.xls) , take title directly there each plot? example; have titles these (can saved either .txt or .xls file):

phase_01_water phase_02_membrane phase_03_water phase_04_empty phase_05_water phase_06_water phase_07_full phase_08_water 

how can that? '8phases.txt' has following 8 lines:

-1     1    -1 -1     1     1  1     1     1  1    -1     1 -1    -1    -1  1     1    -1  1    -1    -1 -1    -1     1 

you can if titles in simple txt file in example, can load them this

with open('titles_file.txt') f:     titlelist = f.readlines() 

then matplotlib.axes have method set_title. rewrite loop in more object oriented way

for count,i in enumerate(i_phase):     f = sum(m*np.cos(2*np.pi*l*x/d) m,l in zip(i,n))     fig = plt.figure()     ax = fig.add_subplot(111)     ax.set_title(titlelist[count])     ax.plot(x,f)     fig.savefig(str(count)+'.png')
