Python: Check if there are duplicate values in a given flat list
Python List: Exercise - 271 with Solution
Write a Python program to check if there are duplicate values in a given flat list.
Use set() on the given list to remove duplicates, compare its length with the length of the list.
Sample Solution:
Python Code:
def has_duplicates(lst):
return len(lst) != len(set(lst))
nums = [1, 2, 3, 4, 5, 6, 7]
print("Original list:")
print(nums)
print("Check if there are duplicate values in the said given flat list:")
print(has_duplicates(nums))
nums = [1, 2, 3, 3, 4, 5, 5, 6, 7]
print("\nOriginal list:")
print(nums)
print("Check if there are duplicate values in the said given flat list:")
print(has_duplicates(nums))
Sample Output:
Original list: [1, 2, 3, 4, 5, 6, 7] Check if there are duplicate values in the said given flat list: False Original list: [1, 2, 3, 3, 4, 5, 5, 6, 7] Check if there are duplicate values in the said given flat list: True
