    -    print("Hi Alice")
+    print(f"Hi {name}")

     def add(a, b):
-    return a - b
+    return a + b
    Commit the changes.
  4. Switch back to the main branch.

The final result should be something like this:

    %%{init: { 'theme': 'default', 'gitGraph': {'mainBranchName': 'main'}} }%%
    commit id: "[HEAD → main] ..."
