Requesting please if someone would be so kind as to review my cod for this initial project, thank you everyone in advance for your help.

# create the initial variables below
age = 28
sex = 0
bmi = 26.2
num_of_children = 3
smoker = 0
# Add insurance estimate formula below
insurance_cost = 250 * age - 128 * sex + 370 * bmi + 425 * num_of_children + 24000 * smoker - 12500
print("This person's insurance cost is " + str(insurance_cost) + " dollars.")
# Age Factor
age += 4
new_insurance_cost = 250 * age - 128 * sex + 370 * bmi + 425 * num_of_children + 24000 * smoker - 12500
change_in_insurance_cost = new_insurance_cost - insurance_cost
print("The change in cost of insurance after increasing the age by 4 years is " + str(change_in_insurance_cost) + " dollars.")
# BMI Factor
age = 28
bmi += 3.1
new_insurance_cost = 250 * age - 128 * sex + 370 * bmi + 425 * num_of_children + 24000 * smoker - 12500

# Male vs. Female Factor
bmi = 26.2
sex = 1

# Extra Practice
sex = 0
