`Hi everyone,

What cause the difference when I change the line of “return estimated_cost” in the below function?

1/

```
# Create calculate_insurance_cost() function below:
def calculate_insurance_cost(name, age, sex, bmi, num_of_children, smoker):
estimated_cost = 250*age - 128*sex + 370*bmi + 425*num_of_children + 24000*smoker - 12500
return estimated_cost
print('The estimated insurance cost for' + name + 'is' + str(estimated_cost) + 'dollars.')
# Estimate Maria's insurance cost
calculate_insurance_cost(name = 'Maria', age = 28, sex = 0, bmi = 26.2, num_of_children = 3, smoker = 0)
# Estimate Omar's insurance cost
calculate_insurance_cost(name = "Omar", age = 35, sex = 1, bmi = 22.2, num_of_children = 0, smoker = 1)
```

=> generate no value
