SELECT |
It is an anonymous function which can be used as a parameter function with sorted/sort,bisect,map,filter,reduce
>> lambda x: x*2;
>> lambda (x,y) : x+y
It is used to perform some operations on all items of sequence in one line and get a map object is iterable and can be converted to sequence
