 DataX task type for executing DataX programs. For DataX nodes, the worker will execute `${DATAX_HOME}/bin/datax.py` to analyze the input json file.
 
+By default, the datax.py will be executed by python2.7, if you want to use other python version, you can set the `DATAX_PYTHON` environment variable to specify a version.

 DataX 任务类型，用于执行 DataX 程序。对于 DataX 节点，worker 会通过执行 `${DATAX_HOME}/bin/datax.py` 来解析传入的 json 文件。
 
+默认会使用python2.7去执行datax.py，如果需要使用其他版本的python去执行datax.py，需要在环境变量中配置`DATAX_PYTHON`。
