Python Program: Checking and handling ellipsis in variables
Write a Python program that checks if a variable is equal to ... and prints a message if it matches.
Sample Solution:
Code:
# Define a list with ellipsis as a placeholder
nums = [1, 2, 3, 4, 5, 6, ...]
for item in nums:
if item is ...:
print("Skipping...")
continue
print(f"Reading item: {item}")
Output:
Reading item: 1 Reading item: 2 Reading item: 3 Reading item: 4 Reading item: 5 Reading item: 6 Skipping...
The exercise above defines a list 'nums' with 'ellipsis' as a placeholder for unspecified items. In the loop, we check if the current item is 'ellipsis (...)', and if it is, we print "Skipping...". Otherwise, we process the item and print a message indicating that we are processing it. By using 'ellipsis' as a marker for skipped or unspecified items, we can iterate over an unknown number of items.
