Def - Return Question

[tryingtolearnpython]

Hi Everyone,

I'm trying to understand the below code. My question is why is it returning salary_bins?

So from what I understand it first defines the table columns, creates the bins and then draws the histograms.

But the return part I'm not sure I fully understand. I tried to run it with return salary_bins and it created the histograms as well.

Thanks in advance.

def histograms(t):
    ages = t.column('Age')
    salaries = t.column('Salary')
    age_bins = np.arange(min(ages),max(ages)+1,1)
    salary_bins = np.arange(min(salaries), max(salaries)+1000000,1000000)
    t.hist('Age', bins=age_bins, unit='year')
    t.hist('Salary', bins=salary_bins, unit='$')
    return age_bins # Keep this statement so that your work can be checked
    
histograms(full_data)
print('Two histograms should be displayed below')
