Disable the output of matplotlib pyplot


Question

I have an array A of shape (1000, 2000). I use matplotlib.pyplot to plot the array, which means 1000 curves, using

import matplotlib.pyplot as plt
plt(A)

The figure is fine but there are a thousand lines of:

<matplotlib.lines.Line2D at 0xXXXXXXXX>

Can I disable this output?

This output is what the plt function is returning (I presume here you meant to write plt.plot(A)). To suppress this output assign the return object a name:

_ = plt.plot(A)

_ is often used to indicate a temporary object which is not going to be used later on. Note that this output you are seeing will only appear in the interpreter, and not when you run the script from outside the interpreter.
