Please check the following FAQ for some guidance on formatting code for the forums and other information that helps anyone attempting to answer a query.
Indentation is Python is how code is grouped together and is a syntax requirement rather than a suggestion. Do you have some empty whitespace before that print function on line 3?
Something like the following would throw an error due to the indentation of the fourth line-
print("start")
#My name is Gustavo Carvalho
#I like icecream
print(" GGG “)
All those indents before your print statements would be a cause for errors, you’d want to bring them back to the left hand side. Perhaps I wasn’t clear enough but you can’t simply add indents to the code at random spots. It follows certain syntax and then requires an indent such as if statements and class definitions.
