+# Get all callables from a file
+
+You can conveniently use the `ast` module for this:
+
+```
+import ast
+
+def get_callables_from_file(filename):
+    with open(filename, 'r') as f:
+        content = f.read()
+
+    tree = ast.parse(content)
+
+    callables = []
+
+    def visit_callables(node):
+        if isinstance(node, (ast.FunctionDef, ast.AsyncFunctionDef)):
+            callables.append(node.name)
+        elif isinstance(node, ast.ClassDef):
+            # Inside a class, continue checking for methods
+            for child in ast.iter_child_nodes(node):
+                if isinstance(child, (ast.FunctionDef, ast.AsyncFunctionDef)):
+                    callables.append(f"{node.name}.{child.name}")
+
+        for child in ast.iter_child_nodes(node):
+            visit_callables(child)
+
+    visit_callables(tree)
+
+    return callables
+
+# Example usage:
+filename = 'path_to_your_file.py'
+print(get_callables_from_file(filename))
+```
