Common errors

Most beginner errors come from four causes: inconsistent indentation, a missing :, mixing Python/Baobab keywords, or using a value before it exists.

❌ Missing colon

1
2
si age >= 18
    afficher("Adulte")

Every si, pour, fonction… must end with :. Here it's missing after 18.

❌ Python keyword in a .bao file

1
print("Adulte")

In a .bao file, use the Baobab vocabulary: afficher, not print. Baobab refuses to run a Python keyword and tells you the expected equivalent.
