PandasSeries.str.the split()function is used to split the one-string column value into two columns based on a specified separator or delimiter. This function works the same asPython.string.split()method, but the split() method works on all Dataframe columns, whereas theSeries.str.split()func...
Explanation: Created a DataFrame with full names combined into one column. Used str.split() to split the 'Full_Name' column into two new columns: 'First_Name' and 'Last_Name'. Returned the DataFrame with the separated name columns. For more Practice: Solve these Related Problems: Write a ...
