Yes. Take this bit of toy code which I just dreamed up. (Of course it
is toy code; don't bother telling me how it could be written better.)
If it looks a bit ragged, pretend it is in a fixed font.
if dow==0: day="Mon"; calcPay()
if dow==1: day="Tue"; calcPay()
if dow==2: day="Wed"; calcPay()
if dow==3: day="Thu"; calcPay()
if dow==4: day="Fri"; calcpay()
if dow==5: day="Sat"; calcPay(rate=1.5)
if dow==6: day="Sun"; calcPay(rate=2)
The point is: when you have several short bits of code with an identical
or similar pattern, *vertically aligning* the corresponding parts can
IMO make it much easier to read the code and easier to spot errors.
Compare this:
if dow==0:
day="Mon"
calcPay()
if dow==1:
day="Tue"
calcPay()
if dow==2:
day="Wed"
calcPay()
if dow==3:
day="Thu"
calcPay()
if dow==4:
day="Fri"
calcpay()
if dow==5:
day="Sat"
calcPay(rate=1.5)
if dow==6:
day="Sun"
calcPay(rate=2)
Not so easy to spot the mistake now, is it?
Not to mention the saving of vertical space.
Best wishes

PS If you really care, I can send you a more complicated example of real
code from one of my programs which is HUGELY more readable when laid out
in this way.
