*****************************************************

names = ['xx','yy','cc']

for name in names:
    exec("%s_mar = []" % name)
    some code...
    else:
       pass

I need help with loop one function and creating variables - code below doesn't work

for name in names:
    eval("%s_var)" % name) = countAll('{0}_mar'.format(name))
    else:
       pass

don't create names dynamically, use dict instead

thx for replay
also need help with this

time = countAll(x_mar)
#this works

name = 'x'
time = countAll('{0}_mar'.format(name))
#this doesn't work

You are not listening and keep trying to create variables names dynamically. Almost always and certainly in this case it's a bad idea.
Please put your question in broader context and elaborate what your goal is, so we can understand and try to help you better
