# Common mistakes
# ─────────────────────────────────────────────

# Wrong — condition at the wrong place (SyntaxError)
# result = if score >= 60 "Passed" else "Failed"

# Wrong — trying to run code, not assign a value (SyntaxError)
# if score >= 60 else print("Failed")

# Wrong — nested ternaries (works, but unreadable)
# result = "A" if score >= 90 else "B" if score >= 70 else "C"

# Quick reference

# value = something if condition else something_else
#
# ternary only works for simple if / else — no elif
# condition goes in the middle
# if it's hard to read — use the full if / else instead
# never nest ternaries
