I created in stata a list of all files in a folder with the following: global file_all : dir "$outputsfolder" files
I encountered the below peculiar behaviour when creating difference of string sets in python: set(['a', 'b']) - set(['a']) #
I have two dataframes, say df1 and df2, with the same column names. example: df1 c1 | c2
What is the difference between difference() and symmetric_difference() methods in python sets?
