+
+```python
+from strands import Agent

+agent = Agent(tools=[programmatic_tool_caller, calculator])
+
+# Code runs in async context automatically - just use await
+result = agent.tool.programmatic_tool_caller(
+    code="""

+result = await calculator(expression="2 + 2")
+print(f"Result: {result}")
+
+# Loop with tool calls

+for i in range(1, 6):
+    square = await calculator(expression=f"{i} ** 2")
