any filter python 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
