Symptoms</h2> <p>The <code>IndexError: index X is out of bounds for axis Y with size Z</code> (or simply <code>IndexError: list index out of range</code>) occurs when attempting to access an element in a sequence (list, tuple, string, or array) using an index outside its valid range. Valid indices for a sequence of length <code>n</code> are from <code>0</code> to <code>n-1</code> (positive) or <code>-1</code> to <code>-n</code> (negative).</p> <p>Common manifestations:</p> <ul> <li><code>IndexError: list index out of range</code> – Most frequent, on lists.</li> <li><code>IndexError: tuple index out of range</code> – On immutable tuples.</li> <li><code>IndexError: string index out of range</code> – On strings.</li> <li><code>IndexError: index 5 is out of bounds for axis 0 with size 3</code> – NumPy arrays, specifying axis.</li> </ul> <p>Stack traces point to the exact line:</p>
