The **function **in **Python **where **comments **are used to explain each line is as follows:

#This **defines **the **parts() function**

def parts(length, width, height, radius):

#This **calculates **the **volume** of the **box**

VBox = length * width * height

#This **calculates **the **volume** of the **hole**

VHole = 3.142 * radius ** 2 * height

#This **calculates **the **remaining volume**

Volume = VBox - VHole

#This **returns **the **volume **of the **remaining material**

return Volume

The above **program **is a **sequential program**, and it does not require **loops**, **iterations **and **conditions**.
