First, the chi2_contingency function is being called. This function is typically used to perform a chi-square test of independence on a contingency table.

The contingency_table variable is being passed as an argument to the chi2_contingency function. This table represents the observed frequencies of two categorical variables.

The chi2_contingency function returns two values: the chi-square statistic and the p-value. In this case, the p-value is being assigned to the variable pval.

The p-value represents the probability of observing the observed frequencies in the contingency table, assuming that the two categorical variables are independent. A low p-value suggests that there is a significant association between the variables, while a high p-value suggests that there is no significant association.
