How many elements does the L list contain? ``python 1 L = [i for i in range(-1, -2)] ``

Question

1 L = [i for i in range(-1, -2)]

Options

• Aone
• Btwo
• Cthree
• Dzero

• A
  2% (1)
• B
  4% (2)
• C
  11% (5)
• D
  82% (37)

Explanation

range(-1, -2) produces an empty sequence because the default step is +1, meaning it would try to count upward from -1 toward -2 - but -1 is already greater than -2, so there are no valid values to yield. The list comprehension iterates over nothing, leaving L = [] with zero elements.

Why the distractors are wrong:

• A (one): A common trap - you might assume -1 is included since it's the start, but range() only yields start when the sequence can actually progress toward stop.
• B (two): There's no scenario where both -1 and -2 are included; range() never includes the stop value.
• C (three): Completely unfounded - no values in [-1, -2) with step +1 exist.

Memory tip: Think of range(start, stop) as "count up from start as long as the value is still less than stop." If start >= stop with the default step, you get zero elements - the range is already "past the finish line" before it begins.
