Suppose I have a function a(i) in PARI/GP code. To evaluate something like a(5) in sage code I write pari('a[5]'). However, running the for loop on pari('a[i]') doesn't seem to work. Is there a work around for this?

Running

for i in range(n):
    pari('a[i]')

won't work since 'a[i]' is a string. Try something like this instead:

for i in range(n):
    pari('a[%d]' %(i))

This will actually substitute the values i takes on into the string expressions you want to evaluate.
