Python: Count float number in a given mixed list using lambda
Write a Python program to count float values in a mixed list using lambda.
Sample Solution:
Python Code :
# Define a function 'count_integer' that takes a list 'list1' as input
def count_integer(list1):
# Create a boolean list 'ert' indicating whether each element in 'list1' is a float or not
ert = list(map(lambda i: isinstance(i, float), list1))
# Count the number of 'True' values (floats) in the boolean list 'ert'
result = len([e for e in ert if e])
# Return the count of floats in the input list
return result
# Create a mixed list containing integers, strings, and floats
list1 = [1, 'abcd', 3.12, 1.2, 4, 'xyz', 5, 'pqr', 7, -5, -12.22]
# Print the original mixed list 'list1'
print("Original list:")
print(list1)
# Print the number of floats in the mixed list using the 'count_integer' function
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
