[issue35871] Pdb NameError in generator param and list comprehension

2019-01-31 Thread Jayanth Raman 


Jayanth Raman  added the comment:

Thanks for the "interact" tip.

FWIW, I see this issue in 2.7.10 as well.  Although the list comprehension 
works.

[issue35871] Pdb NameError in generator param and list comprehension

2019-01-31 Thread Jayanth Raman 


New submission from Jayanth Raman :

I get a NameError for a variable in the generator param of a function or in a 
list comprehension.  See example below.  The variable is available to the 
program, but not to the interactive Pdb shell.

# Test file:

def main(nn=10):
xx = list(range(nn))
breakpoint()
for ii in range(nn):
num = sum(xx[jj] for jj in range(nn))
print(f'xx={xx}')

if __name__ == '__main__':
main()

xx=[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]


FWIW python3 is a homebrew installation.  I had the same issue with 3.7.0 as 
well (also homebrew):

[issue35738] Update timeit documentation to reflect default repeat of three

2019-01-14 Thread Jayanth Raman 


New submission from Jayanth Raman :

In the Examples section of the timeit documentation, repeat() returns a list of 
size three.  But the default is now five and the documentation should reflect 
that.
Thanks.

[issue21330] Typo in Unicode HOWTO documentation

2014-04-22 Thread Jayanth Raman 

New submission from Jayanth Raman:

It should be 128 such characters in the following sentence:

For example, you can’t fit both the accented characters used in Western Europe 
and the Cyrillic alphabet used for Russian into the 128-255 range because there 
are more than 127 such characters.

[issue13410] String formatting bug in interactive mode

2011-11-15 Thread Jayanth Raman 

New submission from Jayanth Raman raman.jaya...@gmail.com:

With file xx.py:

class Foo(object):
def __init__(self, x):
self.x = x
def __long__(self):
return long(self.x)
def __float__(self):
return float(self.x)
y = Foo(22)
print '%d' % y
print '%d' % y


Interactive mode:

$ python -V
Python 2.6.7
$ python -i xx.py
22
22

TypeError: int() argument must be a string or a number, not 'Foo'
 '%d' % y
'22'
 '%d' % y
TypeError: int() argument must be a string or a number, not 'Foo'
 '%d' % y
'22'
 '%d' % y
TypeError: int() argument must be a string or a number, not 'Foo'

It alternates between printing '22' and print a TypeError message.  Expected it 
to be consistent.

Also, the first carraige-return (with no input) results in an error message.  
Did not expect an error message.  In fact, typing pretty much anything (e.g. an 
undefined variable or raise(Exception())) results in the same error message.

Thanks.
