<tt>Hi there,<br>
<br>
I have been using Visual.random number generators and have found that
the following Methods return as <br>
numpy arrays, which when Printed or Evaluated returns a list that is
not separated by the usual commas.<br>
<br>
from visual import *<br>
<br>
print visual.random.sample(5)&nbsp; # floating point list with no commas<br>
print visual.random.permutation(5)</tt><tt> # Integer list with no
commas</tt><br>
<tt>print visual.random.randint(1,46,5)</tt><tt> # Integer list with no
commas</tt><br>
<tt><br>
visual.safe_eval(</tt><tt>str(visual.random.randint(1,46,5))) #
generates error<br>
<br>
</tt><tt>No commas between elements?!<br>
<br>
A work around is to add .tolist()<br>
<br>
visual.random.sample(5).tolist() # returns normal list of floats<br>
visual.random.permutation(6).tolist()<br>
visual.random.randint(1,46,5).tolist()<br>
visual.safe_eval(str(visual.random.randint(1,46,5).tolist()))<br>
<br>
