We could as consistenly explain that the syntax
for n in range(10) if n%3==0:
body
means
for n in range(10):
if n%3==0:
body
This syntax has also the benefit of avoiding an extra level of
indentation (the one for the if) that bears no real meaning on a
structural level.
I'm sorry, I

Hi,
i was wondering if there is a syntax alike:
for i in range(10) if i > 5:
print i
equivalent to
for i in (for i in range(10) if i>5):
print i
what about :
for i in range(6, 10):
print i
More seriously:
for i in range(10):
if i > 5:
print i

Hi,
i was wondering if there is a syntax alike:
for i in range(10) if i > 5:
print i
You can write
for i in filter(lambda i: i > 5, range(10)):
print i
but
for i in range(10):
if i > 5:
print i
it' better readable, and
for i in range(6,10):
print i
it's e

AFAIK, no syntax fo that. But the standard syntax is not too
different:
