Subscript assignment in Python 3.9

What I did

I want to see live coding variable values for a numpy array created as below and assigning a value to one of the element.

import numpy as np

tempArr = np.zeros(5)
tempArr[0] = 0 #problematic line
print(tempArr)

What happened

Everything works but as soon as assignment expression is executed no output is shown in live code. (PyCharm plugin)

tempArr[0] = 0

What I wanted to happen

I would like to print all lines in live code including assignment line as blank line.

tempArr = array([0., 0., 0., 0., 0.])

print('[0. 0. 0. 0. 0.]')

My environment

Describe the versions of everything you were using:

• Editor PyCharm
• Operating system MacOS
• Python 3.9

Other feedback

I a new python learner and enjoyed Live Code thoroughly. Planning to use it as much as possible but above error is stopping me to use it. Thanks for making such a great tool !

Thanks for the bug report. It looks like a problem with Python 3.9, so I’ll dig into it. It doesn’t seem related to numpy, because this fails in the same way:

tempArr = [0] * 5
tempArr[0] = 0  # problematic line
print(tempArr)

There’s probably some new class in the ast module that I have to support.
