I am importing from qiskit.circuit.library import MCMTVChain on python IDLE editor but it showing error ModuleNotFoundError: No module named 'qiskit.circuit.library' although it's working fine on google colab. Also why Qiskit does not work properly on python IDLE it's show lots of other error not just this one?

You most probably haven't installed the qiskit module. Qiskit can be installed via :

pip install qiskit

Try the following commands in command prompt, one of them should work (if your PATH variables are appropriately set):

py -m pip install qiskit


python -m pip install qiskit

Or if you have more than one python versions, you can try:

py -'version number like 3.7' pip install qiskit

without the quotes.

This should install the qiskit module and then you can import it.
