Now you try!

With the functions that you have learnt so far, write a function with function header:

draw$\_$house$($height$,$ breadth, roof$\_$base$)$

This function will draws a house of height $($to the base of the roof$)$ height units, of breadth breadth units

and the roof is root$\_$base units wide. Calling draw$\_$house $(100,150,200)$ will result in something like the

following. It does not matter how the roof of the house looks like, but make sure your drawn house is left$-$

and$-$right symmetrical.You might have learnt some of the Python Turtle functions in lecture$/$tutorial$.$ Here are a few questions to

really test your understanding of how they work, and a very simple drawing to get you acquainted with

drawing with Turtle!

Some of the functions covered are:

pd$()$: Pen down. Any movements thereafter will be traced

pu $()$ : Pen up$.$ Any movements thereafter will NOT be traced

forward $($distance$)$ : Moves the turtle forward a number of units specified by distance

backward$($distance$)$ : Moves the turtle backward a number of units specified by distance

right $($degrees$)$ : Turns the turtle right by a certain number of degrees specified

left $($degrees$)$ : Turns the turtle left by a certain number of degrees specified

$($Note: the direction functions forward, backward, right and left all have shorthands, which are

$fd,bk($or back$),$ rt and $lt$ respectively. Use any of these shorthands or full names as you prefer.$)$

Warmup

In the following sequences of function calls, try to imagine what will be drawn. Then, run the calls yourself

on Python. Did it draw what you had expected? $($Note: This part is not graded and is only for your own

practice. There is no need to copy your answers from this part to Coursemology$)$
