**Code Block:**

import jetbrains.buildServer.configs.base as base
import jetbrains.buildServer.configs.python as python

# 创建一个新的构建配置
build_config = base.Build(id="MyBuild", name="My Build")

# 添加一个Python构建步骤
python_step = python.PythonBuildStep(id="PythonStep", name="Python Step")
python_step.script_file = "my_script.py"
python_step.interpreter_path = "/usr/bin/python3"

# 将Python构建步骤添加到构建配置
build_config.steps.add(python_step)

**Line-by-line Code Logic Interpretation:**
