help needed

[Naley2010]

hi i need help to write two different functions

the first one is to displaysquareroots that asks the user for a number n, and displays the square roots of the number from 1 to n and to 3dp
so if the user enters 3 it displays

the square root of 1 is 1.000
the square root of 2 is 1.414
the square root of 3 is 1.732

the second one is to write a function peasinapod that asks the user for a number, and then draws that number of "peas" (green circles of radius 50) in a "pod" (graphics window of exactly the right size). E.g if the user enters 4, a graphics window of the size 400x100 should appear

and there is a third one write a numbered square function that has a parameter n and displays a "numbered" square of size n e.g a cqall numberedsquare(4) should result in

0 1 2 3
1 2 3 4
2 3 4 5
3 4 5 6

thank you

You forgot your code and error messages, don't forget to push (CODE) before pasting.

[Naley2010]

they are too long to add and they are wrong as it doesn't produce what I need

[TrustyTony]

First and third problem at least are short problems, we want to know about you from the code you wrote, so we can help you best way.

[Naley2010]

for the first one i wrote
def drawdisplaySquareRoots():
n = input("Enter a number: ")
from math import sqrt
for n in range(1, n, 3):
root = sqrt(n)
print n

and the thrid one

def drawnumberedSquare(n):
#n = input("Enter a number wanted for the size of the square: ")
for i in range(1, n):
for j in range(1, n):
for k in range(1, n):

Not so far, actually, here is corrected first one, but you did forget to push that (CODE) button first!

def list_of_roots(): # function names are writen in small letters
    number = input("Enter a number: ")
    from math import sqrt
    for n in range(1, 1+number): # not every third, do not reuse n, not step of 3
        root = sqrt(n)
        print "the square root of %i is %.3f" % (n, root)

list_of_roots()

[TrustyTony]

Third one partially corrected, show your own effort to make this work, hints should be enough to get you there:

def make_square(n):
    for i in range(1, n):
        for j in range(i, n):
##          for k in range(1, n): there is two dimensions in square
            print '%1i' % j,
        print

# it is better to get input out of action and pass the parameter              
n = input("Enter a number wanted for the size of the square: ")
make_square(n)

Actually almost nobody uses input statement in Python2, but instead use raw_input and convert the numbers themselves. Input has two much power, so if you know how you can call any functions to do damage to the computer system.

hi i have another problem which is to write a wall of eyes function that takes 3 parameters (radius,width and height) and displays, in a window of exactly the right size a wall of brown eyes of the given radius and dimensions e.g the function call wallofeyes(50, 4, 2) would give a 400x200 graphics window with 8 eyes using x's instead of eyes to look like

xxxx
xxxx

please help so far i have

def drawBrownEyeInCentre():
win = GraphWin()
centreOfWindow = Point(100,100)
drawCircle(win, Point(100,100), 60, "white")
drawCircle(win, Point(100,100), 30, "brown")
drawCircle(win, Point(100,100), 15, "black")

def drawwallOfEyes(radius, width, height):
win = GraphWin()
centreOfWindow = Point(100,100)
drawCircle(win, Point(100,100), 60, "white")
drawCircle(win, Point(100,100), 30, "brown")
drawCircle(win, Point(100,100), 15, "black")

[TrustyTony]

You must loop for row and column and do right amount of step between them to produce not fixed values for center points.

i don't understand how to do that?

Perhaps you should visit the tutor centre in Lion Gate building.
