<s>[INST] import pandas as pd

# Sample data:
data = {
    'countries': ['USA', 'Canada', 'Germany', 'UK', 'France', 'Belgium', 'Switzerland'],
    'capitals': ['Washington', 'Ottawa', 'Berlin', 'London', 'Paris', 'Brussels', 'Bern'],
    'populations': [331, 38, 83, 67, 65, 11, 8]
}

# Step 1: Create DataFrame
df = pd.DataFrame(data)

# Step 2: Process Data
df = df.sort_values(by='populations', ascending=False)

# Step 3: Write to File
df.to_csv('output.csv', index=False)

# Step 4: Verify File and Quit
print(pd.read_csv('output.csv').head())
df.quit()

QUIT COMMAND - Optional (If get stuck) 
# df.quit() df.__del__()



I have run this piece of code in Spyder, but when using it in an IDE PyCharm, df.quit() does not work and gets a Bug Error. 'DataFrame' object has no attribute 'quit'

How do I quit the DataFrame - The code doesn't require the data frame after processing, will deleting DataFrame free the memory or resource


In Python, we don't have manual memory management, but we can use the del command to free memory. Can I use another IDE command for quit or what I want is memory deallocation (memory cleanup)?[/INST]
