Hi,
I just know that '_' is the last result in the Python interpreter. I feel that
it is like 'ans' in Matlab. When I run the following commands. The result of
'_' are always '4'.
Because I have tried several commands, such as reversed('fred'), xx and rx,
'4' are always there.
What is your explanation about the following?
Thanks,
>>> reversed('fred')
<reversed object at 0x02A8DD50>
>>> _
'4'
>>> _
'4'
>>> xx
33223
>>> _
'4'
>>> rx=reversed('fred')
>>> _
'4'
>>> xx
33223
>>> _
'4'
>>>
