Set commom xticks (string) for subplots using Matplotlib

Given a set of subplots, I'd like to set common xticks labels for them. I know how to do that when the ticks are numerical:

cmap = plt.get_cmap('Set3')
colors = [cmap(i) for i in numpy.linspace(0, 1, 18)]

data_1 = numpy.random.rand(18, 7)
data_2 = numpy.random.rand(18, 7)
data_3 = numpy.random.rand(18, 7)
data_4 = numpy.random.rand(18, 7)

y = range(365)
plt.figure(figsize=(15,7))
for i in range(18):
    plt.plot(y, data_1[i, :], color=colors[i], linewidth=2)
    plt.plot(y, data_2[i, :], color=colors[i], linewidth=2)
    plt.plot(y, data_3[i, :], color=colors[i], linewidth=2)
    plt.plot(y, data_4[i, :], color=colors[i], linewidth=2)
plt.setp(axes, xticks=range(7))
plt.tight_layout()

enter image description here

However, now I'd like my ticks label to be strings. Given that, I tried something like this:

plt.setp(axes, xticks=(range(12), ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']))

But it doesn't work:

ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

Thank you.

You can manually set strings on your xticks as shown in the example below:

x = [1,2,3,4,5,6,7,8,9,10,11,12]
y = [1,2,3,4,5,6,7,8,9,10,11,12]

plt.plot(x,y)
my_xticks = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']

plt.xticks(x, my_xticks)
plt.show()
