835
Given Input:
roll_number = [47, 64, 69, 37, 76, 83, 95, 97]
sample_dict = {'Jhon':47, 'Emma':69, 'Kelly':76, 'Jason':97}
Expected Output:
After removing unwanted elements from list [47, 69, 76, 97]
Program:
roll_number = [47, 64, 69, 37, 76, 83, 95, 97]
sample_dict = {'Jhon': 47, 'Emma': 69, 'Kelly': 76, 'Jason': 97}
print("List:", roll_number)
print("Dictionary:", sample_dict)
# create new list
roll_number[:] = [item for item in roll_number if item in sample_dict.values()]
print("after removing unwanted elements from list:", roll_number)
Output:
List: [47, 64, 69, 37, 76, 83, 95, 97]
Dictionary: {'Jhon': 47, 'Emma': 69, 'Kelly': 76, 'Jason': 97}
