"a = list(a[i] for i in range(0,len(a)))" in python Usage of Generators

 a=[1,2,3,4,5]

k = list(a[x] for x in range(len(a)))

print(k)

a=[1,2,3,4,5]

k = list(a[x] for x in range(len(a)))

print(k)

f = (x for x in a if x%2 == 0) 

print(list(f))

syntax :

variable0 = (variable1 for variable1 in array_name if variable1 % 2 == 0 )

print(variable0)

as above the example inferred single line use of for  loop
