Python: Count integer in a given mixed list
Python List: Exercise - 106 with Solution
Write a Python program to count integers in a given mixed list.
Sample Solution:
Python Code:
def count_integer(list1):
ctr = 0
for i in list1:
if isinstance(i, int):
ctr = ctr + 1
return ctr
list1 = [1, 'abcd', 3, 1.2, 4, 'xyz', 5, 'pqr', 7, -5, -12.22]
print("Original list:")
print(list1)
print("\nNumber of integers in the said mixed list:")
print(count_integer(list1))
Sample Output:
Original list: [1, 'abcd', 3, 1.2, 4, 'xyz', 5, 'pqr', 7, -5, -12.22] Number of integers in the said mixed list: 6

Python: Tips of the Day
Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:
Example:
def tips_check_prop(fn, prop): return lambda obj: fn(obj[prop]) check_age = tips_check_prop(lambda x: x >= 25, 'age') user = {'name': 'Owen', 'age': 25} print(check_age(user))
