Python: Count float number in a given mixed list using lambda

Python Lambda: Exercise-32 with Solution

Write a Python program to count float number in a given mixed list using lambda.

Sample Solution:

Python Code :

def count_integer(list1):
    ert = list(map(lambda i: isinstance(i, float), list1)) 
    result = len([e for e in ert if e])         
    return result
list1 = [1, 'abcd', 3.12, 1.2, 4, 'xyz', 5, 'pqr', 7, -5, -12.22]
print("Original list:")
print(list1)
print("\nNumber of floats in the said mixed list:")
print(count_integer(list1))

Sample Output:

Original list:
[1, 'abcd', 3.12, 1.2, 4, 'xyz', 5, 'pqr', 7, -5, -12.22]

Number of floats in the said mixed list:
3
