In general: this snippet filters out those values('$dollar', '@at','%modulu' ) that do not contain '
#x27; and '%' symbols. lambda operator creates an unnamed function that runs function 'any' through the values list. 'any' itself returns those elements that contains '
#x27; and '%' symbols. But 'not any' does a inverse selection. That is why you get those values that DO NOT contain '
#x27; and '%' symbols: f = lambda x: not any(p in x for p in fil) here: 'p in fil' runs across the list of
#x27; and '%' symbols one by one. So 'p' first takes '
#x27; and then in 'p in x' checks whether 'x' contains this synbol. Then the same goes with '%' synbol. 'x' in its turn is a variable that takes a value from the list ['$dollar', '@at','%modulu'].

Looks like you've missed a comma in your list: lst = ['$dollar', '@at', '%modulu'] ^this one
