What does dataframe.loc[;, variable, variable] indicate?-CodePudding

I understand that with dataframe.loc[:, "variable1", "variable2"] - variable1 is the start, variable2 is the end so what is the purpose of the ;?

Specifically, this line of code has confused me https://www.kaggle.com/code/apapiu/regularized-linear-models

all_data = pd.concat(
    (
        train.loc[:, 'MSSubClass': 'SaleCondition'],
        test.loc[:, 'MSSubClass': 'SaleCondition']
    )
)

CodePudding user response：

Look at your code snippet (arguments of both invocations of loc):

: means: all rows,
'MSSubClass':'SaleCondition' means take columns from MSSubClass to SaleCondition (inclusive, i.e. without the last column named SalePrice).

Actually, you should have written:

dataframe.loc[:, "variable1":"variable2"]

Note that the above row does not contain any ";".
