For instance, given the input <code>\"boat\"<\/code>, the output should be <code>\"oat\"<\/code>, and for <code>\"mice\"<\/code>, the output should be <code>\"ice\"<\/code>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">1. <strong>Understanding String Indexing<\/strong><\/h4>\n\n\n\n<p>In Python, strings are indexed collections of characters. The first character is at index <code>0<\/code>, the second at <code>1<\/code>, and so on. So for the string <code>\"boat\"<\/code>, we have:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>\"b\"<\/code> at index <code>0<\/code><\/li>\n\n\n\n<li><code>\"o\"<\/code> at index <code>1<\/code><\/li>\n\n\n\n<li><code>\"a\"<\/code> at index <code>2<\/code><\/li>\n\n\n\n<li><code>\"t\"<\/code> at index <code>3<\/code><\/li>\n<\/ul>\n\n\n\n<p>To return everything <em>except<\/em> the first character, we start slicing the string from index <code>1<\/code>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">2. <strong>Using String Slicing<\/strong><\/h4>\n\n\n\n<p>Python provides a feature called <em>slicing<\/em>, which lets you extract portions of sequences like strings, lists, and tuples. The syntax is:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopyEdit<code>string[start:stop]\n<\/code><\/pre>\n\n\n\n<p>When you use <code>word[1:]<\/code>, it means:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Start at index <code>1<\/code> (skipping the first character).<\/li>\n\n\n\n<li>Go all the way to the end of the string.<\/li>\n<\/ul>\n\n\n\n<p>So <code>word[1:]<\/code> effectively removes the first character and returns the rest.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">3. <strong>Function Definition<\/strong><\/h4>\n\n\n\n<p>The function is defined using the <code>def<\/code> keyword. It takes one parameter <code>word<\/code>, and returns the result of slicing it from the second character onward.<\/p>\n\n\n\n<p>This exercise helps reinforce your understanding of string indexing and slicing in Python \u2014 fundamental concepts in string manipulation and data processing.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner9-206.jpeg\" alt=\"\" class=\"wp-image-230238\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Exercise 7.2.6: If You&#8217;re Not First, You&#8217;re Last Write the function called end_of_word that takes a string and returns everything but the first character. end_of_word(&#8220;boat&#8221;) = &#8220;oat&#8221;
