Use a list of values to select rows from a Pandas dataframe
Another method;
df.loc[df.apply(lambda x: x.A in [3,6], axis=1)]Unlike the isin method, this is particularly useful in determining if the list contains a function of the column A. For example, f(A) = 2*A - 5 as the function;
df.loc[df.apply(lambda x: 2*x.A-5 in [3,6], axis=1)]It should be noted that this approach is slower than the isin method.
