Greetings @ivo000, congratulations on finishing your project. The presentation style of your project looks nice, it is easy to follow. Consider the following.
Explanations - Add more explanations for your project. Let your readers know what you are doing and why you are doing it. Also, explain your findings.
Efficiency - you could make this code more efficient by using a python built-in function Enumerate which adds a counter to an iterable and returns it in a form of enumerate object.
Your New Column Names and Indexes code
for i in range(len(autos.columns)):
print(i, autos.columns[i])
This is how it could look like if you use enumerate:
for i, col in enumerate(autos.columns):
print(i, col)
Conclusion - Your project is missing a conclusion, provide a conclusion to summarize the findings of your project.
Further Improvements - As you continue learning, especially data visualization, return to this project and add some plots, this aids in seeing more insights.
