Verification commands (re-run from a fresh clone)

# D4 — all tests pass
python -m unittest -q
# Expected: 18 tests, 0 failures, exit 0

# D2 — operator/paren sequence
python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize('1+2*3')])"
# Expected: ['NUMBER', 'PLUS', 'NUMBER', 'STAR', 'NUMBER', 'EOF']

# D1 + D2 + D3 combined
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('3.5*(1-2)')])"
# Expected: [('NUMBER', 3.5), ('STAR', None), ('LPAREN', None), ('NUMBER', 1), ('MINUS', None), ('NUMBER', 2), ('RPAREN', None), ('EOF', None)]

# D3 — LexError on invalid char
python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"
# Expected: raises calc.lexer.LexError: invalid character '@' at position 2

What is claimed (DoD items)

• D1: Integers and floats → NUMBER token with numeric value (int or float).
  • tokenize("42") → [NUMBER(42), EOF] (int)
  • tokenize("3.14") → [NUMBER(3.14), EOF] (float)
  • tokenize(".5") → [NUMBER(0.5), EOF] (float)
  • tokenize("10.") → [NUMBER(10.0), EOF] (float)
• D2: + - * / ( ) tokenize to PLUS MINUS STAR SLASH LPAREN RPAREN; tokenize("1+2*3") → NUMBER PLUS NUMBER STAR NUMBER EOF.
• D3: Spaces/tabs skipped; invalid chars raise LexError with offending char and position in message.
  • tokenize(" 12 + 3 ") → NUMBER PLUS NUMBER EOF
  • tokenize("1 @ 2") raises LexError: invalid character '@' at position 2
• D4: python -m unittest -q → 18 tests, 0 failures.
