SyntaxError: “can't assign to function call”

Question

This line in my program:

invest(initial_amount,top_company(5,year,year+1)) = subsequent_amount

causes me to get this error:

Answer 1

You wrote the assignment backward: to assign a value (or an expression) to a variable you must have that variable at the left side of the assignment operator ( = in python )

subsequent_amount = invest(initial_amount,top_company(5,year,year+1))
