Python2 --Range
1.It produces a list for itertions.
For x in range(3):
         print x
O/p:
0
1
2

y = range(5)

MishraKhushbu

Basic Examples:
1.{ x^2: x is a natural number less than 10 }
[x*2 for x in range(0,10)]
2.{ x: x is a whole number less than 20, x is even }
[x for x in range(0,20) if x%2 == 0]
3.{ x: x is an alphabet in word ‘MATHEMATICS’, x is a vowel }
[x for x in "MATHEMATICS" x not in "AEIOU"]
=======================================================================================
The same gets implemented in a simple LC construct in a single line as:
 [ output_expression() for(set of values to iterate) if(conditional filtering) ]

For every Program Mary wrote,
the lambda was all she needed to know
