Python -- passing multiple variables from a list of names -

this question has answer here:

• how create variable number of variables? 12 answers

i able bunch of variables names listed in array, example:

import numpy np nsim=100 vec in ['lgx1','lgx2','lgx3']: vec=np.random.uniform(low=0.0, high=1.0, size=nsim) 

this doesn't produce compilation error, doesn't seem want either (i.e., doesn't set 3 arrays named lgx1, lgx2 , lgx3 of random uniformly drawn variables). more compact having 1 such command each of arrays. suggestions? of still speaking supermongo, looking python analog of

foreach vec {lgx1 lgx2 lgx3} {set $vec=random(100)} 

many thanks!

do not try use variable names constructed variable. instead, use dictionary:

import numpy np  nsim=100 arrays = {}  vec in ['lgx1','lgx2','lgx3']:     arrays[vec] = np.random.uniform(low=0.0, high=1.0, size=nsim) 

now have arrays['lgx1'] , on.

or, since looks varying "names" single digit, use list:

lgx = []  _ in range(3):     lgx.append(np.random.uniform(low=0.0, high=1.0, size=nsim)) 

your arrays lgx[0], lgx[1], , lgx[2].

this can written in single statement list comprehension:

lgx = [np.random.uniform(low=0.0, high=1.0, size=nsim) _ in range(3)] 

either way, easy work arrays group.
