This means you can access their values using <a href=\"https:\/\/careerkarma.com\/blog\/python-index\/\">indexing and slicing<\/a>. These techniques allow you to retrieve an individual character or range of characters from a string.<br><\/p>\n\n\n\n<p>In this guide, we discuss how to remove the last character from a Python string. We\u2019ll walk through an example of removing the last character from a string so you can figure out how you can accomplish this task in your code.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Python: Remove Last Character from String<\/h2>\n\n\n\n<p>We want to build a program that removes the last character from an employee identifier. This character tells us the department for which an employee works.<br><\/p>\n\n\n\n<p>For instance, the value \u201cM\u201d tells us an employee works for the marketing department. We are going to remove this character because it is being replaced by a new system to keep track of the department for which an employee works.<br><\/p>\n\n\n\n<p>Let\u2019s start by asking the user to insert an employee identifier using the <a href=\"https:\/\/careerkarma.com\/blog\/python-input\/\">input() method<\/a>:<\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre>identifier = input(&quot;What is the employee's identifier? &quot;)<\/pre><\/div>\n\n\n\n<p>Next, we remove the last character from the identifier:<\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre>new_identifier = identifier[:-1]<\/pre><\/div>\n\n\n\n<p>The [:-1] is a <a href=\"https:\/\/careerkarma.com\/blog\/python-substring\/\">string slice operation<\/a> that removes the last character from the list. We use negative indexing to retrieve items from the end of the string. Now, display an employee\u2019s new identifier to the console:<br><\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre>print(&quot;The employee's new identifier is {}.&quot;.format(new_identifier))<\/pre><\/div>\n\n\n\n<p>The <a href=\"https:\/\/careerkarma.com\/blog\/python-f-string\/\">.format() statement<\/a> replaces the curly braces inside our string with the employee\u2019s new identifier. Let\u2019s run our code and see what happens:<br><\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre>What is the employee's identifier? 28371M\nThe employee's new identifier is 28371.<\/pre><\/div>\n\n\n\n<p>Our program removes the last value in an employee\u2019s identifier.<br><\/p>\n\n\n\n<p>We\u2019re not done yet. If a user inserts a blank value, our program returns:<br><\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre>The employee's new identifier is .<\/pre><\/div>\n\n\n\n<p>We should make this more graceful. To do so, we need to slice an employee\u2019s identifier if the identifier has more than two characters. Otherwise, our program will inform the user they need to insert a valid identifier.<br><\/p>\n\n\n\n<p>Let\u2019s define an <a href=\"https:\/\/careerkarma.com\/blog\/python-if-else\/\">\u201cif\u201d statement<\/a> that checks for the length of an identifier:<br><\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre>identifier = input(&quot;What is the employee's identifier? &quot;)\n\nif len(identifier) &gt; 1: \n\t     new_identifier = identifier[:-1]\n\t     print(&quot;The employee's new identifier is {}.&quot;.format(new_identifier))\nelse:\n\t     print(&quot;Please insert a valid identifier.&quot;)<\/pre><\/div>\n\n\n\n<p>We use the <code>len()<\/code> method to find out the length of an employee\u2019s identifier. If the length of that identifier is greater than \u201c1\u201d, our <code>if<\/code> statement executes. Otherwise, the \u201celse\u201d statement runs.<br><\/p>\n\n\n\n<p>Let\u2019s run our Python program and specify an identifier that is less than two characters long:<br><\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre>What is the employee's identifier? B\nPlease insert a valid identifier.<\/pre><\/div>\n\n\n\n<p>Our code informs us we need to choose a valid identifier.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Slicing syntax lets you delete the last character from a string object in Python. All you need to do is specify a string and add [:-1] after the string. Now you\u2019re ready to remove the last character from a Python string like an expert!<\/p>\n","protected":false},"excerpt":{"rendered":"Strings are iterable objects.
