Converting a column within pandas dataframe from int to string

| | | | | |

I have a dataframe in pandas with mixed int and str data columns. I want to concatenate first the columns within the dataframe. To do that I have to convert an int column to str. I"ve tried to do as follows:

mtrx["X.3"] = mtrx.to_string(columns = ["X.3"])

or

mtrx["X.3"] = mtrx["X.3"].astype(str)

but in both cases it"s not working and I"m getting an error saying "cannot concatenate "str" and "int" objects". Concatenating two str columns is working perfectly fine.

Python functions is always a bit confusing 😭 Converting a column within pandas dataframe from int to string is not the only problem I encountered. I just hope that will not emerge anymore

I was preparing for my coding interview, thanks for clarifying this - Converting a column within pandas dataframe from int to string in Python is not the simplest one. Will use it in my bachelor thesis
