inbuilt fuction of chezbezo filter code example
Example 1: filter function in python
nums1 = [2,3,5,6,76,4,3,2]
def bada(num):
return num>4 # bada(2) o/p: False, so wont return.. else anything above > value returns true hence filter function shows result
filters = list(filter(bada, nums1))
print(filters)
(or)
bads = list(filter(lambda x: x>4, nums1))
print(bads)
Example 2: python - filter function
# Filter function
def with_s(student):
return student.startswith('s')
students = ['sarah', 'mary', 'sergio', 'lucy'] # define a list
s_filter = filter(with_s, students) # filter() returns true or false
print(next(s_filter)) # filter() returns a generator
print(list(s_filter)) # give all elements of the generator
