Good Day, I'm trying to run the code in Intro-to-QC from the web page:
https://towardsai.net/p/programming/introduction-to-quantum-computing-with-python-and-qiskit, and
I'm receiving an error:

Traceback (most recent call last):
File "C:\dl\coding\python\0projects\scientific\quantum-calculations\simple-tests\Qiskitsampletest01.py", line 39, in
File "C:\dl\coding\python\0projects\scientific\quantum-calculations\simple-tests\Our_Qiskit_Functions.py", line 51, in Wavefunction
value = round(statevec[i].real, dec) + round(statevec[i].imag, dec) * 1j
File "c:\bin\python396\lib\site-packages\qiskit\quantum_info\states\statevector.py", line 219, in getitem
raise QiskitError("Key must be int or a valid binary string.")
qiskit.exceptions.QiskitError: 'Key must be int or a valid binary string.'

I'm running Python 3.9.6 and Qiskit 0.20.1 I'm also running Python from the command line by running the code
3 or 4 lines at a time.

Thanks for your tutorial.
