<h3>Python Tuple</h3>
<hr>
<h4>Tuples</h4>
<p>A Tuple can be defined as a ordered collection of objects which are <b>immutable</b>. <br>
<p>Tuples are also sequences just like lists.But the main difference between these 2 is lists are mutable(can be changed) but tuples are immutable(cannot be changed) unlike lists.<br>
Tuples uses <b>parentheses()</b>.</p>
<b>Example:</b><br>
<pre><code>tup1=('Computer','Laptop',30,70);
tup2=(1,2,3,4,5);
tup3=(50,); # a single valued tuple also contain <b>comma(,)</b>
</code></pre>
<p>To create an empty tuple:</p>
<pre><code><b>tup1=();</b></code></pre>
<p>Like strings, tuple index also starts from 0 and they can be sliced,concatenated and so on.</p><br>
<h5>Accessing tuple values</h5>
<p>To access the tuple values,we use the <b>square brackets[ ]</b> for slicing along with the index or indices to obtain value available at the index.It is similar to string.</p><br>
<b>Example:</b>
<pre><code>tup1=('Computer','Laptop',30,70);
tup2=(1,2,3,4,5);
print(tup1[0])
print(tup2[3])
</code></pre>
<b>Output:</b>
<pre><code>Computer
4
</code></pre>
<p>Slicing can also be used in tuples as mentioned above.Let's take an example:</p><br>
<b>Example:</b>
<pre><code>tup3=(12,23,34,45,56,67,78,89);
print(tup3[3:7])
</code></pre>
<b>Output:</b>
<pre><code>[45,56,67,78]</code></pre>
<h5>Updating Tuples</h5>
<p>As said earlier,tuples are immutable that means it cannot be changed or updated.You can see below what happens if we try to change the tuple variable.</p>
<img src="pythonphoto/tuple1.PNG" alt="tuples are immutable" width="60%">
<h5>Deleting Tuple </h5>
<p>Deletion of tuple elements is not possible because tuples are immutable.However, the entire tuple can be deleted by keyword <b>del</b>.It deletes the entire tuple.</p>
<pre><code>tup1=('Computer','Laptop',30,70);
print(tup1)
<b>del</b> tup1
</code></pre>
<p>The above code will remove the entire tuple.</p>
<h5>Built-in Tuple functions</h5>
<ol>
<li><b>len(tuple1)</b><br>
This function will give the total length of the tuple.
<pre><code><b>Code:</b>
tup3=(12,23,34,45,56,67,78,89);
print(len(tup3))
<b>Output:</b>
8
</code></pre></li>
