#======================Function Definitions

# ----- draw a box with x,y at lower left corner. 
def drawBox (x , y, size, color):
     turtle.penup()       # stop drawing 
     turtle.goto(x,y)

     turtle.pendown()     # start drawing 
     turtle.pencolor(color) 

     turtle.setheading(0)  # facing east 
     turtle.forward(size)
     turtle.left(90)      # north 
     turtle.forward(size) 
     turtle.left(90)      # west 
     turtle.forward(size)
     turtle.left(90)       # south 
     turtle.forward(size)
     turtle.penup()


#=====================START HERE 

drawBox( 0,0, 50, "blue")
drawBox(-100, -100, 100, "green")
drawBox(-300, -300, 200, "black")
drawBox(-310, -310, 200, "black") 


# Your assignment: 
# Write a function called drawFlower(x, y).  It takes arguments x and y
# and draws a pretty flower at location (x,y).

# Your flower should have more than one petal: also write a function called
# drawPetal (x,y) that draws an individual petal. OK to add more arguments
# for color or angle if you like.

# Your drawFlower function should call the drawPetal function multiple
# times to draw the separate petals.

# Don't forget to call drawFlower from the main code section! 


# Variations on the assignment: ok to try one of these instead. 
# Try these ideas
# 1.  Define a function that draws one of your initial letters (such as
#     drawM or drawC.   Then define a drawMonoGram function that writes
#     your initial letter multiple times, to make a fancy monogram/logo.
#     You can do this by changing the starting point,  the original heading,
#     and/or the pen color.

# 2.  Define a function that draws a picture of Lord Jeff at the specified
#     coordinates.  Then call it multiple times to make an army of Jeffs..

# 3.  Write a new drawBox method that also takes as an argument a
#     heading to start the turtle at.  Call it with different start
#     locations and headings to make a pretty spiral-type pattern.

# 4.  Try using recursion to get the drawBox function to repeat a pattern
#     either shifting it or shrinking it, or both.  BUTNOTE this should
#     only be done if you can figure out how to includ an if statement to
#     stop infinite recursion.  We will talk about this next week.
