The decision vlob

```
In [3]: from random import randint
In [4]: def t(list_len=10):
list_ = []
while len(list_) < list_len:
r = randint(0, list_len * 10)
if r not in list_: list_.append(r)
return list_
...:
In [5]: t()
Out[5]: [34, 21, 49, 40, 81, 78, 95, 63, 31, 29]
In [6]: t(20)
```

In the face prettier, I think, not to solve it. But you can replace the list of two randomness on the tuple, and the list of lists - set-om...at least at the time of filling.

Get a little nicer (at least from my point of view) :

If you still a list of lists, then the last line replace with

while len(a) < dots:
a.add((randint(0, dots), randint(1, dots)))

If you still a list of lists, then the last line replace with

`return [list(i) for i in list(a)]`

Simple and much faster

```
def generate(dots):
dot = list(range(dots))
for i in range(dots):
x = random.randrange(0, dots)
dot[i] , dot[x] = dot[x], dot[i]
return dot
dot = generate(dots)
```

In the task list of lists...

you can make zip(generate(dots),generate(dots)) - get a list of tuples

or map(lambda x,y:[x,y],generate(dots),generate(dots)) - will be a list of lists commented on August 19th 19 at 23:19

Your option is generally easier to solve using set

from random import randint

def t (list_len=10):

list_ = set()

while len(list_) < list_len

list_.add(randint(0, list_len * 10))

return list(list_)

ps indentation think it is clear where. - barrett_Kohler commented on August 19th 19 at 23:15
