How do I change the entire column value in Pandas?
For example: >>> df.
ID Name Number. 0 A abc 123. 1 B def 456. If I want to change the value in the Name column, how do I write the code to replace all abc with xyz.map(lambda x: re.map()
This is just a map operation over the DataFrame - it creates a dictionary and maps the string values in the rows of the DataFrame with the new values provided as the mapping.map(lambda x: 'abc' if not x else 'xyz') The lambda here performs this operation on each string in the row - the first time the condition is True, it replaces the string abc with xyz, otherwise it returns the string.
