Python coding

The tax calculator program of the case study outputs a floating-point number that might show more than two digits of precision.

Use the round function to modify the program to display at most two digits of precision in the output number.

Below is an example of the program input and output:

Enter the gross income: 12345.67 Enter the number of dependents: 1 The income tax is $-130.87

Starter code:

Compute a person's income tax.

1. Significant constants

tax rate

standard deduction

deduction per dependent

2. The inputs are

gross income

number of dependents

3. Computations:

taxable income = gross income - the standard deduction -

a deduction for each dependent

income tax = is a fixed percentage of the taxable income

4. The outputs are

the income tax

"""

# Initialize the constants

TAX_RATE = 0.20

STANDARD_DEDUCTION = 10000.0

DEPENDENT_DEDUCTION = 3000.0

# Request the inputs

grossIncome = float(input("Enter the gross income: "))

numDependents = int(input("Enter the number of dependents: "))

# Compute the income tax

taxableIncome = grossIncome - STANDARD_DEDUCTION - \

DEPENDENT_DEDUCTION * numDependents

incomeTax = taxableIncome * TAX_RATE

# Display the income tax

print("The income tax is $" + str(incomeTax))
