How to not insert the same combination of values in a list?


How to not insert the same combination of values in a list?

Any of those help I currently have a matrix that is 6x3 containing different probabilities. , Using set(lista) will remove any duplicate values
Example:
code :
lista = [1,2,3,4,1,2]
new_list = set(lista)
print(new_list)
{1, 2, 3, 4}
import itertools

lista = [[1,2,3], [1,2,3], [3,4,5]]
new_list = list(k for k,_ in itertools.groupby(lista))
print(new_list)
[[1, 2, 3], [3, 4, 5]]

hope this fix your issue you can create a unique key of the combination of W_ID and TC_ID then perform your upsert on it as follows:
code :
CREATE TABLE sample 
    (
     id int auto_increment primary key, 
     W_ID varchar(20), 
     TC_ID varchar(20),
      foo varchar(20),
      bar varchar(20)
    );

alter table sample add constraint UNIQUE (W_ID, TC_ID);

INSERT INTO sample 
(W_ID, TC_ID,foo,bar)
VALUES ('1', '2','123','123');
INSERT INTO sample 
(W_ID, TC_ID,foo,bar)
VALUES ('2', '2','123','123');
INSERT INTO sample 
(W_ID, TC_ID,foo,bar)
VALUES ('3', '2','123','123');
INSERT INTO sample 
(W_ID, TC_ID,foo,bar)
VALUES ('1', '4','123','123');
INSERT INTO sample 
(W_ID, TC_ID,foo,bar)
VALUES ('2', '3','123','123');

INSERT INTO sample 
(W_ID, TC_ID,foo,bar)
VALUES ('1', '2','123','123')
ON DUPLICATE KEY UPDATE
`foo` = 'newFoo';
ID  W_ID    TC_ID    FOO    BAR
1   1   2            newFoo 123
2   2   2            123    123
3   3   2            123    123
4   1   4            123    123
5   2   3            123    123
