Yes, tuples can contain duplicate values in Python. Unlike sets, tuples allow duplicate values to be present in them. You can define a tuple with duplicate values by simply listing the values separated by commas, just like any other tuple.
For example, consider the following tuple:
my_tuple = (1, 2, 3, 2, 4, 1)
In this tuple, the values 1 and 2 appear twice. This is perfectly valid in Python, and you can access these values using indexing or slicing.
print(my_tuple[0]) # Output: 1
print(my_tuple.count(2)) # Output: 2
Here, the count() method returns the number of times a specific value appears in the tuple. In this case, the value 2 appears twice, so the count() method returns 2.
