Hi can some please explain why this error message is coming up?
What does pandas.read_csv expect and what is being passed to it? That error means that there’s no object with that name/identifier in the current scope. It’s no different than a statement like
print(x) when no variable named
Here’s the link to the relevant docs-
all.csv should be wrapped in quotation marks like “all.csv” or ‘all.csv’
