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))

Output:

True
