The aim of this article is to provide details on how to convert a string to a float. To convert a String to a float in Python, use the float() function.<\/p>\n<p><strong id=\"Using_float()\">Float()<\/strong><\/p>\n<p>Any data form can be converted to a floating-point number using this function.<\/p>\n<p><strong>Syntax:<\/strong><\/p>\n<p><code class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\">float(object)<\/code><\/p>\n<p>Only one parameter is accepted by the process, and it is also optional to use. The method returns 0.0 if no argument is transmitted.<\/p>\n<p><strong>Parameters:<\/strong><\/p>\n<ul>\n<li>An int, float, or string may be used.<\/li>\n<li>If it&#8217;s a string, it has to be in the right decimal format.<\/li>\n<\/ul>\n<p><strong>Return:<\/strong><\/p>\n<ul>\n<li>It gives you a float object as a result.<\/li>\n<li>ValueError will be raised if the given string contains something other than a floating-point representation of a number.<\/li>\n<li>If no argument is given, 0.0 is returned.<\/li>\n<li>Overflow Error is raised if the given statement is beyond the range of float.<\/li>\n<\/ul>\n<p>Let&#8217;s look at some examples of how to convert a string to a float object using the float() function.<\/p>\n<p>Assume we have a Str object with the string \u201834.124&#8242;. We&#8217;ll transfer the string to the float() function to convert it to a floating-point number, or float entity. Which returns the float object after converting this string to a float. As an example,<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"python\"># Driver code\r\n\r\n# given string value\r\nstringval = '34.124'\r\n\r\n# converting string to float\r\nfloatvalue = float(stringval)\r\n\r\n# printing the float number\r\nprint(floatvalue)\r\n\r\n# printing the type of the number\r\nprint('Type of the number\/object :', type(floatvalue))\r\n<\/pre>\n<p><strong>Output:<\/strong><\/p>\n<pre id=\"codeOutputPre\">34.124\r\nType of the number\/object : &lt;class 'float'&gt;<\/pre>\n<h3 id=\"Convert_a_comma-separated_number_string_to_a_float_object\">Convert a comma-separated number string to a float object<\/h3>\n<p>Let&#8217;s say we have a string called &#8216;34,123.454&#8217;\u00a0 which includes the number but also some commas. It&#8217;s a little difficult to convert this type of string to float. If we transfer this to the float() function directly, we&#8217;ll get an error as below:<\/p>\n<pre>ValueError: could not convert string to float: '34,123.454'<\/pre>\n<p>float() returned an error since string contained characters other than digits. So, before passing the string to the float() function, we need to delete all the extra commas.<\/p>\n<p>We use replace function to replace commas with blank character such that commas\u00a0 are deleted<\/p>\n<p>Below is the implementation:<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"python\"># Driver code\r\n\r\n# given string value\r\nstringval = '34,123.454'\r\n\r\n# convert string with comma to float\r\n# replacing ,(comma) with blank value\r\nfloatvalue = float(stringval.replace(',', ''))\r\n\r\n# printing the float number\r\nprint(floatvalue)\r\n\r\n# printing the type of the number\r\nprint('Type of the number\/object :', type(floatvalue))\r\n<\/pre>\n<p><strong>Output:<\/strong><\/p>\n<pre id=\"codeOutputPre\">34123.454\r\nType of the number\/object : &lt;class 'float'&gt;<\/pre>\n<p><strong>Related Programs<\/strong>:<\/p>\n<ul>\n<li><a href=\"https:\/\/python-programs.com\/convert-integer-to-string-in-python\/\">convert integer to string in python<\/a><\/li>\n<li><a href=\"https:\/\/python-programs.com\/how-to-convert-a-python-string-to-int\/\">how to convert a python string to int<\/a><\/li>\n<li><a href=\"https:\/\/python-programs.com\/python-convert-list-to-string\/\">python convert list to string<\/a><\/li>\n<li><a href=\"https:\/\/python-programs.com\/python-how-to-convert-integer-to-string\/\">python how to convert integer to string<\/a><\/li>\n<li><a href=\"https:\/\/python-programs.com\/python-how-to-convert-datetime-object-to-string-using-datetime-strftime\/\">python how to convert datetime object to string using datetime strftime<\/a><\/li>\n<li><a href=\"https:\/\/python-programs.com\/python-convert-string-to-integer\/\">python convert string to integer<\/a><\/li>\n<li><a href=\"https:\/\/python-programs.com\/python-how-to-convert-a-timestamp-string-to-a-datetime-object-using-datetime-strptime\/\">python how to convert a timestamp string to a datetime object using datetime strptime<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>In Python, strings are byte sequences that represent Unicode characters.
