In Python, you can call methods written in Golang by using the subprocess module to start a Golang executable and pass data through standard input and output.<\/p>\n

Here is an example:<\/p>\n

    \n
  1. The main file is named main.go.<\/li>\n<\/ol>\n
    package<\/span> main\r\n\r\nimport<\/span> \"fmt\"<\/span>\r\n\r\nfunc<\/span> main<\/span>()<\/span><\/span> {\r\n    var<\/span> input string<\/span>\r\n    fmt.Scanln(&input)\r\n    fmt.Println(\"Golang received:\"<\/span>, input)\r\n}\r\n<\/code><\/pre>\n
      \n
    1. Compile Golang code to generate an executable file.<\/li>\n<\/ol>\n
      go build main.go\r\n<\/code><\/pre>\n
        \n
      1. Invoke the executable file of Golang in Python.<\/li>\n<\/ol>\n
        import<\/span> subprocess\r\n\r\n# \u542f\u52a8Golang\u53ef\u6267\u884c\u6587\u4ef6<\/span>\r\nprocess = subprocess.Popen(\".\/main\"<\/span>, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True<\/span>)\r\n\r\n# \u5411Golang\u53d1\u9001\u6570\u636e<\/span>\r\ninput_data = \"Hello from Python\"<\/span>\r\nprocess.stdin.write(input_data.encode())\r\nprocess.stdin.close()\r\n\r\n# \u8bfb\u53d6Golang\u7684\u8f93\u51fa<\/span>\r\noutput_data = process.stdout.read().decode().strip()\r\nprint<\/span>(\"Python received:\"<\/span>, output_data)\r\n\r\n# \u7b49\u5f85Golang\u8fdb\u7a0b\u7ed3\u675f<\/span>\r\nprocess.wait()\r\n<\/code><\/pre>\n
        After running the Python code, you will see the following output:<\/p>\n
        Python received: Golang received: Hello from Python\r\n<\/code><\/pre>\n
        Please note that this is just one way to call Golang methods in Python, there are other methods such as using CGO, RPC, etc. The specific method chosen depends on your needs and circumstances.<\/p>\n","protected":false},"excerpt":{"rendered":"
