Hello Tara, or is it Leon?

Hi, im trying to write a script which randomly generates 10,000 points(x,y)

What red? I see no red.
Please do not rely on colour in email, for at least two reasons:
1) For colour to be visible in your email, you must have so-called "Rich Text"
(actually HTML mail) turned on. Many people have HTML mail turned off,
because it is a security and privacy threat, or simply do not appreciate
having somebody else's choice of colour and font being forced on them.
2) About 8% of men and 0.5% of women have red-green colour-blindness, with other
forms of colour-blindness being less common. All up, about 1 in 10 men and 1
in 100 women cannot easily or at all distinguish colours. Others may be
partially or completely blind. Using a screen reader, they can still "read"
the words you send, but will have no idea at all about colours.
however it only produces one random point. How do I get it to repeat this so it
produces 10,000 different random points?
import math
import random
random.seed()
x=random.uniform(0,1)
y=random.uniform(0,1)
This generates one random point, because it gets executed once. After
generating that
single random point, you then loop 1x1 times:
for i in range(0,1): # this line loops once
for j in range(0,1): # and this also loops once
print (x,y)
so it only 1x1 = 1 time.
The solution is simple: if you want to generate 10,000 points, you must put the
code that chooses a random point inside something that will loop 10,000 times.
Here's an example that will loop 20 times:
for i in range(20):
# Pick an x and y ar random
x = random.uniform(0,1)
y = random.uniform(0,1)
print (x, y)
All you have to do now is extend that to loop 10000 times instead of 20.
