passing a column as parameter in python function

Question

I have been trying to store unqiue values in a column from pandas data frame using the following code to further use in the function. Code snippet:

def mergeFields(data,field):

    oldlist = pd.unique(data[field])

data_rcvd_from_satish.tags = mergeFields("data_rcvd_from_satish","tags")

Error: 
TypeError: string indices must be integers, not list

I know the error which i have been getting is similar to many other question still I am not able to resolve the error. I would request not to consider this duplicate and please answer.

Answer 1

data is a string. Please review the arguments passed to mergeFields . you basically wrote:

"data_rcvd_from_satish"["tags"]

which is invalid.
