EasyPython15 min10 XP

Problem

For n, return a list of strings where the first row has one star and each next row has one more star.

Why This Matters

Star patterns train loop boundaries and string multiplication without needing complex algorithms.

Function Signature

def right_triangle_stars(n):

Examples

Example 1
Inputn = 4
Output["*", "**", "***", "****"]

Row i contains exactly i stars.

Constraints

  • Return the exact requested value.
  • Handle small edge cases cleanly.
  • Prefer readable Python over clever shortcuts.
