I want to split each entry by , and feed into respective columns. Number 1 if the value is available and 0 if not available.

My desired output as below

+-------+---+---+---+

+-------+---+---+---+
| X,Y,Z | 1 | 1 | 1 |
+-------+---+---+---+
| Z,X,Y | 1 | 1 | 1 |
+-------+---+---+---+
|  Z,X  | 1 | 0 | 1 |
+-------+---+---+---+
|   Y   | 0 | 1 | 0 |

please guide me how should I approach to solve this.

Answer 1

We have pd.Series.str.get_dummies()

df=df.join(df.Items.str.get_dummies(','))
