How to quickly figure out which list is causing the error?

By -

In a python script, if we have multiple lists in a single expression, for example:

a[1] = b[2] + c[3] + d[4]

OR

a[1] = b[c[d[1]]] # (This case added in EDIT)

Now, one of these lists throws an error IndexError: List Index Out of Range because the index is higher than the list length.

Is there a way to improve this default exception handling using try/except statements such that we can instantly figure out which list caused the problem?

Otherwise, one needs to check each list using a command line debugger. I understand that if an IDE is available, then this feature is probably inbuilt into the IDE.

Spring Elasticsearch Operations

Network Error and Timeout on Authorize.net JS

By -
i am using authorize.net acceptUI.js in order to create a hosted payment form for credit card acceptance. The problem arising now is that, going on the checkout page, I have the following console message: GET https://js.authorize.net/v3/AcceptUI.js net::ERR_NAME_NOT_RESOLVED Which is weird, cause I cannot ping the domain or anything, as my computer cannot resolve the domain. However, this issue is also reported by individual customers and it seems to be sporadically and not happening the entire time, cause i can see other orders going through. Does anyone know how such an error can be caused, or any ideas how it can be resolved? Thanks for your help EDIT: I just checked the A DNS record for js.authorize.net and am getting the following result only: js.authorize.net. 100 IN CNAME js.authorize.net.cdn.cloudflare.net. Doing the same for js.authorize.net.cdn.cloudflare.net. does not return an A Record, unless I specifically instruct to use 1.1.1.1 as DNS server I...
