Let's break down the code: Creating the data variable: data = ((1, 2),) * 7 The tuple (1, 2) is wrapped inside another tuple, ((1, 2),). This tuple is repeated 7 times using the * operator, creating: data = ((1, 2), (1, 2), (1, 2), (1, 2), (1, 2), (1, 2), (1, 2)) Slicing data: data[3:8] Slicing starts from index 3 (inclusive) and ends at index 8 (exclusive). However, since data only has 7 elements (index 0 to 6), the slice data[3:8] only includes elements from index 3 to the end of the tuple: ((1, 2), (1, 2), (1, 2), (1, 2)) Calculating the length of the slice: len(data[3:8]) The slice contains 4 elements, so len(data[3:8]) returns 4. Final Output: 4

Let's break down the code step by step to understand the output: data = ((1, 2),) * 7: ((1, 2),) creates a tuple containing a single tuple element (1, 2). * 7 repeats this tuple 7 times. So, data will be ((1, 2), (1, 2), (1, 2), (1, 2), (1, 2), (1, 2), (1, 2)). print(len(data[3:8])): data[3:8] slices the list starting from index 3 up to but not including index 8. Since the tuple has 7 elements, the slice data[3:8] will include elements at indices 3, 4, 5, and 6, which gives you ((1, 2), (1, 2), (1, 2), (1, 2)). The len() function then calculates the length of this slice, which is 4.
