I'm a beginner and I'm learning Python by myself.

My current code：

pd.DataFrame(cigarettedata['state'].value_counts())
pd.DataFrame(cigarettedata['price'].value_counts())

Does the price of cigarettes vary by from state to state, what state is best for buying？

How should I write the code for this question? Thank you.

If your just learning, I would start with some basic understanding of the language.

• Learn basic python syntax
• Learn how to use the print statement
• Learn about variables
• Learn about functions
• Learn about OOP and classes
• Learn about loops when any why to use

What you provided does not do anything. Your using a pandas dataframe without showing where the data is coming from or how it is to be used.
Just my 2 cents.

That's great! Learning a programming language on your own can be a challenging but rewarding experience.
Here is an example of how you could write the code for this question:

# Create a dataframe with state and price columns
df = pd.DataFrame(cigarettedata[['state', 'price']])

# Group the dataframe by state and find the price statistics
price_stats = df.groupby('state')['price'].agg(['min', 'max', 'mean'])

# Find the state with the lowest average price
best_state = price_stats[price_stats['mean'] == price_stats['mean'].min()].index[0]

# Print the result
print('The best state for buying cigarettes is ' + best_state + '.')
