The meta-data can include your company or organization name, computer name, revisions or versions, author name etc.<\/li>\n<li>A <a href=\"https:\/\/docs.python.org\/3\/library\/shutil.html#shutil.SameFileError\" target=\"_blank\" rel=\"nofollow\">SameFileError<\/a> occurs if you provide same source and destination files.<\/li>\n<li>An OSError exeception is raised if the destination location is not writeable.<\/li>\n<\/ul>\n<h3><strong>Using copy function<\/strong><\/h3>\n<p>If you require copying the file content along with certain meta-data information then use the copy function. However, the copy function only copies the <strong>permission mode<\/strong> of the file along with content.<\/p>\n<p>It does not copy file creation time or modification (meta-data). For that, you may use the copy2 method (see next section).<\/p>\n<p>The general syntax for using the copy method is:<\/p>\n<blockquote><p>shutil.copy(src_file, dst_file, *, follow_symlinks=True)<\/p><\/blockquote>\n<p>You can see, the arguments are the same as the copyfile method.<\/p>\n<p>The example below shows the code of copying a source file to the destination file:<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"python\"># Using copy method of shutli\r\n\r\n\r\n\r\nimport shutil\r\n\r\nshutil.copy(\"python-demo.txt\", \"dest-demo.txt\")<\/pre>\n<p>Just like the above example, I copied the content from python-demo.txt to the empty <em>dest-demo.txt<\/em> file.<\/p>\n<p>Note that if <em>dest-demo.txt<\/em> file did not exist as we executed this code then a new file with the name of dest-demo.txt would have been created with the content and permission mode of the python-demo.txt file.<\/p>\n<h3><strong>The example of copy2 function<\/strong><\/h3>\n<p>As mentioned earlier, if you also require meta-data that includes creation, modification of the source file along with file permission and content then use the copy2 method of the shutli module.<\/p>\n<p>The syntax is the same as we used for the copy function i.e.:<\/p>\n<blockquote><p>shutil.copy2(src, dst, *, follow_symlinks=True)<\/p><\/blockquote>\n<p>The example code shows how to use this function:<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"python\"># Using copy2 method of shutli module\r\n\r\n\r\n\r\nimport shutil\r\n\r\nshutil.copy2(\"demo-copy2.txt\", \"dest-demo-copy2.txt\")<\/pre>\n<h3><strong>An example of copying an excel file from some other directory<\/strong><\/h3>\n<p>Suppose, we have an excel file (test-excel.xlsx) that is stored in the <em>C:\/<\/em> directory. We want to copy it to the <em>D:\/test<\/em> directory. The test directory does not contain that excel file or empty.<\/p>\n<p>For copying the excel file by copy2 method, the code is:<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"python\"># Copy Excel file from one directory to other\r\n\r\n\r\n\r\nimport shutil\r\n\r\nshutil.copy2(\"C:\/test-excel.xlsx\", \"D:\/test\/\")<\/pre>\n<h3><strong>The example of using copyfileobj function<\/strong><\/h3>\n<p>The general syntax of using the copyfileobj method is:<\/p>\n<blockquote><p>shutil.copyfileobj(fource, fdestiny[, length])<\/p><\/blockquote>\n<ul>\n<li>The <em>fsource<\/em> and <em>fdestiny<\/em> specifies the file-like objects.<\/li>\n<li>The length argument is the difference than we used in the above functions.<\/li>\n<li>It specifies the buffer size and provided as an integer.<\/li>\n<li>For avoiding uncontrolled memory consumption, the copyfileobj method reads file data in chunks.<\/li>\n<li>However, if you provide a negative length value, that means not to loop over source file data in chunks.<\/li>\n<li>The copyfileobj is the base function; all other functions we used in the above section call this method at some point.<\/li>\n<li>This method is particularly useful for copying large files. The default buffer size is 16Kb. By using copyfileobj, you may specify a bigger buffer size that other copy method does not allow.<\/li>\n<\/ul>\n<p>The example code below shows copying an excel file from one drive\u2019s folder to another by using the copyfileobj method:<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"python\"># Copy Excel file by copyfileobj method\r\n\r\n\r\n\r\nimport shutil\r\n\r\n\r\n\r\nsrc_file = \"C:\/test-excel.xlsx\"\r\n\r\ndst_file = \"D:\/test\/test-excel.xlsx\"\r\n\r\nbuf_size = 30\r\n\r\n\r\n\r\nwith open(src_file, 'rb') as src:\r\n\r\n\u00a0 with open(dst_file, 'wb') as dest:\r\n\r\n\u00a0\u00a0\u00a0 shutil.copyfileobj(src, dest, buf_size)\r\n\r\nsrc.close()\r\n\r\ndest.close()<\/pre>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this tutorial, I will show you a few ways of copying content of one file to another by using the Python shutli module.<br \/>\nThe shutli module has a few methods for copying the source file content into the destination file.<\/p>\n","protected":false},"author":1,"featured_media":6503,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[17],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v21.5 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>How to Copy File by Python shutli Module [5 Examples]<\/title>\n<meta name=\"description\" content=\"In this tutorial, I will show you a few ways of copying content of one file to another by using the Python shutli module.
