What you wrote would appear to be an infinite loop so I'll assume you meant
to assign something to x each time round the loop as well. The simple
Python translation of what I think you meant would be:
x = 1
while x <= 100:
print x
x += x
If you really insist on doing it with a for loop:
def doubling(start, limit):
x = start
while x <= limit:
yield x
x += x
...
for x in doubling(1, 100):
print x
I was hopping to describe it with only one command. most of the
languages I know use this.
It seems weird to me their is no such thing in python. it's not that I
can't fined a solution it's all about saving code
Do you anticipate reusing it? You could make something a little more
extendable.
for x in iexpression( 'x', 1, 100, 'x+x' ):
print x
or
for x in iexpression( lambda x: x+x, 1, 100 ):
print x
I'm assuming you don't want or have a closed form, in this case x= 2**
_x.
