Code Implementation to Retrieve Hostname using Python<\/h2>\n\n\n\n
Example 1: Using the Platform Module<\/h3>\n\n\n\n
\nimport platform\n\nhostname = platform.node()\nprint("Hostname:", hostname)\n<\/pre><\/div>\n\n\nplatform<\/code> module in python assists in performing platform-related operations like receiving and processing operating system names, versions, etc. platform.node()<\/code> function gets the information from the operating system and returns the string representation of the node name which is usually the hostname of the machine but it can also be a domain name or IP address.<\/p>\n\n\n\n![\"Platform](\"https:\/\/www.askpython.com\/wp-content\/uploads\/2023\/03\/platform_output.png\")
<\/figure>\n\n\n\nExample 2: Using the Socket Module<\/h3>\n\n\n\n
\nimport socket\nprint(socket.gethostname())\n<\/pre><\/div>\n\n\n
socket<\/code> module is used to provide low-level network functionality, by the low-level network I mean the ability to work with the basic building blocks of network communication, such as sockets, IP addresses, and protocols like TCP and UDP. With that, it provided functions and classes for managing sockets and transferring data. The gethostname()<\/code> function retrieves the system hostname.<\/p>\n\n\n\n![\"Socket](\"https:\/\/www.askpython.com\/wp-content\/uploads\/2023\/03\/socket_output.png\")
<\/figure>\n\n\n\nExample 3: Using Platform and OS Modules<\/h3>\n\n\n\n
\nimport platform, os\n\nif platform.system() == "Windows":\n print(platform.uname().node)\nelse:\n print(os.uname()[1])\n<\/pre><\/div>\n\n\n
platform<\/code> and os<\/code> modules. We then use an if-else loop to check if the system is windows or not using platform.system()<\/code> function if it is it will return the system hostname by platform.uname().node<\/code> function. <\/p>\n\n\n\nos.uname()[1]<\/code>.<\/p>\n\n\n\nuname()<\/code> function does not work for the window system.<\/p>\n\n\n\n![\"Os](\"https:\/\/www.askpython.com\/wp-content\/uploads\/2023\/03\/os_output.png\")
<\/figure>\n\n\n\nExample 4: Using Socket Module with IP Address<\/h3>\n\n\n\n
\nimport socket\nprint(socket.gethostbyaddr(socket.gethostname())[0])\n<\/pre><\/div>\n\n\n
![\"Gethostbyaddr](\"https:\/\/www.askpython.com\/wp-content\/uploads\/2023\/03\/gethostbyaddr-Function_output.png\")
