[New-bugs-announce] [issue3490] Example Code Error in Tutorial Documentation

[Adam]

New submission from Adam <yoshokun at gmail.com>:

In section 4.4 of the Python Tutorial
(http://docs.python.org/tut/node6.html) there is a code example using
prime numbers that results extraneous output. The else is incorrectly
indented one tab too far to the right and is nested under (for x in
range) rather than (for n in range).

Current:

>>> for n in range(2, 10):
...     for x in range(2, n):
...         if n % x == 0:
...             print n, 'equals', x, '*', n/x
...             break
...     else:
...         # loop fell through without finding a factor
...         print n, 'is a prime number'
... 

Correct:

>>> for n in range(2, 10):
...     for x in range(2, n):
...         if n % x == 0:
...             print n, 'equals', x, '*', n/x
...             break
...  else:
...      # loop fell through without finding a factor
...      print n, 'is a prime number'
...
