34. Student Height/Weight Filter Lambda

Write a Python program to filter the height and width of students, which are stored in a dictionary using lambda.

Sample Solution:

Python Code :

# Define a function 'filter_data' that takes a dictionary 'students' as input
def filter_data(students):
    # Use the 'filter' function with a lambda function to filter dictionary items based on height and weight conditions
    # Only items with height > 6.0 and weight > 70 are kept in the resulting dictionary 'result'
    result = dict(filter(lambda x: (x[1][0], x[1][1]) > (6.0, 70), students.items()))
    
    # Return the filtered dictionary
    return result  

# Create a dictionary 'students' with student names as keys and tuples representing height and weight as values
students = {
    'Cierra Vega': (6.2, 70),
    'Alden Cantrell': (5.9, 65),
    'Kierra Gentry': (6.0, 68),
    'Pierre Cox': (5.8, 66)
}

# Print the original dictionary 'students'
print("Original Dictionary:")
print(students)

# Filter the dictionary 'students' based on height > 6ft and weight > 70kg using the 'filter_data' function
print("\nHeight > 6ft and Weight > 70kg:")
print(filter_data(students))

Sample Output:

Original Dictionary:
{'Cierra Vega': (6.2, 70), 'Alden Cantrell': (5.9, 65), 'Kierra Gentry': (6.0, 68), 'Pierre Cox': (5.8, 66)}

Height> 6ft and Weight> 70kg:
{'Cierra Vega': (6.2, 70)}
