Python dataframe = Replace values in column string with values from another dataframe

By -

I have the following dataframe (RuleDF) with a column which contains a string.
Inside the string are some values (parameters) which shall be replaced
eg. param1 and param2

Rule_ID Rule_Value
R-123 column1 > param1 and column2 > param2
R-456 column1 > param1
... ...

There is another Dataframe (RuleMapDF) with the mapping:
Rule_ID Rule_Param Param_Value
R-123 param1 100
R-123 param2 200
R-456 param1 100

The result of the replacement will be something like this:
Another option is to have a new column with the replaced string

Rule_ID Rule_Value
R-123 column1 > 100 and column2 > 200
R-456 column1 > 100
... ...

I appreciate any ideas. Thank you.

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...
