Can somebody explain how this works? df.columns = list(map(str, df.columns))
1 Answer
Your code is not the best way to convert column names to string, use instead:
df.columns = df.columns.astype(str)
Your code:
df.columns = list(map(str, df.columns))
is equivalent to:
df.columns = [str(col) for col in df.columns]
map: for each item in df.columns (iterable), apply the function str on it but the map function returns an iterator, so you need to explicitly execute list to generate the list.
