Python Filter
Filter Overview
The filter() method filters the given sequence with the help of a function that tests each element in the sequence to be true or not.
ages = [5, 12, 17, 28, 24, 32]
def myFunc(x):
if x > 18:
return False
else:
return True
adults = filter(myFunc, ages)
#print(adults)
print(list(adults))
#for x in adults:
# print(x)
# a list contains both even and odd numbers.
seq = [0, 1, 2, 3, 5, 8, 13]
# result contains odd numbers of the list
#result = filter(lambda x: x % 2, seq)
#print(list(result))
# result contains even numbers of the list
result = filter(lambda x: x % 2 == 0, seq)
print(list(result))
