pythondev | help | It looks like you want to loop over `data['search']['wp']['features']`, and for each feature, loop over `feature['phoneNumbers']`. However, it's not necessarily clear from this example whether that will always work, or if there are other places phone numbers could show up in `'geo'` or `'yp'`, etc. | 2019-03-16T23:00:04.849200 | Sasha | pythondev_help_Sasha_2019-03-16T23:00:04.849200 | 1,552,777,204.8492 | 13,825 |
pythondev | help | I'd also be wary of assuming that every feature has a phone number associated with it, so you probably want a lot of error-checking. | 2019-03-16T23:02:09.850100 | Sasha | pythondev_help_Sasha_2019-03-16T23:02:09.850100 | 1,552,777,329.8501 | 13,826 |

pythondev | help | A *real* newbie here. Q: Is there a char version of range(10)? ex: “for somechar in range(a-z)” perhaps? Thanks! | 2019-03-16T23:39:52.852600 | Rob | pythondev_help_Rob_2019-03-16T23:39:52.852600 | 1,552,779,592.8526 | 13,828 |
pythondev | help | Good question. I'm not aware of one, unfortunately. The usual practice would be either to have an explicit alphabet string constant to iterate through, or to construct the values from `range()` integers using `ord()` and `chr()`. | 2019-03-16T23:44:27.854100 | Sasha | pythondev_help_Sasha_2019-03-16T23:44:27.854100 | 1,552,779,867.8541 | 13,829 |

pythondev | help | Per your input, I tried this and it appears to work:
`asciiint: int

pythondev | help | sorry: new to this. I’ll try formatted for code :
`asciiint: int`
`for asciiint in range(97, 123):`
`print(chr(asciiint))` | 2019-03-17T00:08:12.857800 | Rob | pythondev_help_Rob_2019-03-17T00:08:12.857800 | 1,552,781,292.8578 | 13,832 |
pythondev | help | Great! For ease of readability, you can also do `range(ord('a'), ord('z') + 1)` if you want. | 2019-03-17T00:09:10.858500 | Sasha | pythondev_help_Sasha_2019-03-17T00:09:10.858500 | 1,552,781,350.8585 | 13,833 |

pythondev | help | The easiest method I can think of is to start from the K+1 position (if there is one), then iterate backwards until you hit a space (or the beginning of the string), and truncate there. | 2019-03-17T11:52:04.865100 | Sasha | pythondev_help_Sasha_2019-03-17T11:52:04.865100 | 1,552,823,524.8651 | 13,835 |
pythondev | help | Hmm interesting solution <@Sasha>, thanks! But to be honest I still don’t know how to properly solve it in Python.

pythondev | help | <@Sasha> nice solution, and sim to what I was thinking. But your first conditional will return true if the last character is a space | 2019-03-17T12:24:02.870500 | Hiroko | pythondev_help_Hiroko_2019-03-17T12:24:02.870500 | 1,552,825,442.8705 | 13,840 |

pythondev | help | Good point. I was wondering whether the input is allowed to have leading or trailing spaces. The problem statement is ambiguous there, but maybe some of the examples would have shown that. | 2019-03-17T12:27:40.872900 | Sasha | pythondev_help_Sasha_2019-03-17T12:27:40.872900 | 1,552,825,660.8729 | 13,842 |

pythondev | help | Kinda a "high level" question (so not sure if this is the right channel). I've been spending a fair amount of time digging into Pandas (and I really enjoy it!). Both tutorials as well as using it to automate some internal reporting. I'm wondering if I might start to suffer "when all you have is a hammer...everything looks like a nail" mentality. Basically, using pandas when a simple list or dictionary might work better. At the end of the day, I suppose as long as it works "right" there's not a huge problem with using pandas (except perhaps some performance issues? but for what I generally do, this isn't a major concern). Anyone have any thoughts regarding if there is a good way to know (or questions I should be asking myself) to identify 'X' as well suited to Pandas and 'Y' better served by a dictionary, list or other 'internal' data data structures? Thanks! | 2019-03-17T18:52:13.893100 | Marth | pythondev_help_Marth_2019-03-17T18:52:13.893100 | 1,552,848,733.8931 | 13,862 |
pythondev | help | I'm not an expert, but I'd say that Pandas is a good tool for multidimensional data (rows and columns, or more), whereas native Python data structures are nicely suited for one-dimensional data (lists, key-and-value, etc.). | 2019-03-17T18:58:57.894900 | Sasha | pythondev_help_Sasha_2019-03-17T18:58:57.894900 | 1,552,849,137.8949 | 13,863 |

Alternately, can you perform the conversion on the original square-pixel image first before the hex step? | 2019-03-18T01:18:44.903000 | Sasha | pythondev_help_Sasha_2019-03-18T01:18:44.903000 | 1,552,871,924.903 | 13,876 |
pythondev | help | In general, I would not expect things to "just work" between OpenCV and the hex-image libraries. | 2019-03-18T01:20:05.903700 | Sasha | pythondev_help_Sasha_2019-03-18T01:20:05.903700 | 1,552,872,005.9037 | 13,877 |
pythondev | help | what do you mean by performing the original sqaure-pixel image first? | 2019-03-18T01:24:52.903800 | Josef | pythondev_help_Josef_2019-03-18T01:24:52.903800 | 1,552,872,292.9038 | 13,878 |
pythondev | help | Well, you appear to be calling `cvtColor()` to convert the image to grayscale. Can you do that on the original JPEG instead? | 2019-03-18T01:26:47.904000 | Sasha | pythondev_help_Sasha_2019-03-18T01:26:47.904000 | 1,552,872,407.904 | 13,879 |
pythondev | help | yes of course, so you mean to say I perform OpenCV processing first before converting the image to hexagonal pixel? Doesn't it change the main goal of hexagonal image processing where we convert image to hex then do some image processing after? | 2019-03-18T01:29:00.904200 | Josef | pythondev_help_Josef_2019-03-18T01:29:00.904200 | 1,552,872,540.9042 | 13,880 |
pythondev | help | Depends on what your goal is, I guess. But the main point is that you probably shouldn't expect OpenCV to operate on hexagonal images, so you may have to implement your own image processing. | 2019-03-18T01:31:14.904400 | Sasha | pythondev_help_Sasha_2019-03-18T01:31:14.904400 | 1,552,872,674.9044 | 13,881 |
pythondev | help | How can I make a function where I can Apply a 2DFilter on an image? Can I do that ? please help. I want it to be Like this one "cv2.filter2D(img, cv2.CV_8UC3, g_kernel)" because I already have the filter for hexagonal Image but the problem lies on applying the filter on the resampled image. | 2019-03-18T01:33:15.904600 | Josef | pythondev_help_Josef_2019-03-18T01:33:15.904600 | 1,552,872,795.9046 | 13,882 |
pythondev | help | No idea, I'm afraid. You know a lot more about hexagonal images than I do. It's not at all obvious how to generalize 2D filters to hex pixels since the axes are no longer orthogonal. Sounds like some math may be necessary to figure that out. | 2019-03-18T01:43:39.904800 | Sasha | pythondev_help_Sasha_2019-03-18T01:43:39.904800 | 1,552,873,419.9048 | 13,883 |

pythondev | help | hi, i am confused by that problem.
in Yellow line, list - char_dic[c] are using c before " for c in x_str "
what is it grammar in python | 2019-03-18T04:26:52.905900 | Kendall | pythondev_help_Kendall_2019-03-18T04:26:52.905900 | 1,552,883,212.9059 | 13,885 |
pythondev | help | If you're asking how do we call such constructions in python it's list comprehension | 2019-03-18T04:39:55.908500 | Russ | pythondev_help_Russ_2019-03-18T04:39:55.908500 | 1,552,883,995.9085 | 13,886 |
pythondev | help | <@Russ> oh Thank your for reply, So You mean That Constructions is valid on only list? | 2019-03-18T04:59:50.909800 | Kendall | pythondev_help_Kendall_2019-03-18T04:59:50.909800 | 1,552,885,190.9098 | 13,887 |
pythondev | help | ehh.. that particular construction is valid for everything "list-like" (sets, tuples, etc). And in `char_dic` you're using dictionary comprehension, so it's valid too, but it has slightly different syntax. But I recommend you to read about comprehensions in general. It's a very powerful tool that save tons of time. And if you're ready for it, then generators as well. | 2019-03-18T05:05:08.915100 | Russ | pythondev_help_Russ_2019-03-18T05:05:08.915100 | 1,552,885,508.9151 | 13,888 |
pythondev | help | Hello
I'm trying to use a variable introduced in one function in another one.. but it gives that its not defined.. how could this be done, I'm new in python

pythondev | help | With respect to list comprehensions, can somebody explain this behaviour:
```
a = [1,2,3]
[a for a[0] in a]

I can’t wrap my head around what is going on. | 2019-03-18T05:06:24.917200 | Berenice | pythondev_help_Berenice_2019-03-18T05:06:24.917200 | 1,552,885,584.9172 | 13,890 |
pythondev | help | <@Tanja> Variables are scoped, so they cannot be accessed outside their scope (function, class, ...)

pythondev | help | <@Tanja> Try to not use `global` (which will pop up if you google for variable scoping).
