[Tutor] learning python from scratch
dear fellow programmeers, this is michael. I have a question for Python. I'm a beginner Pythonist. I havee been learning the history and it's use for past years. My main focus this year is to learn it's code and begin coding. Where can I find resource for this? All comment are greatly appreciate it Best regards Michael Munn Michael Munn Member: Virginia Association of Blind students National Federation of the Blind of Virginia www.nfbv.org Member: Maryland Association of Blind Students National Federation of the Blind of Maryland www.nfbmd.org Students of: Hadley Institute of the Blind www.hadley.edu ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

with a simple if/elif chain, a switch based on a dict or similar?
You mean create a list with the order=[a,b,e,d...]
Again I've no idea what you're saying here.
depending on how the input file is created data packet a can be in an
other position for every line.
figured out how to do it though
order=[a,b,e,d...]
for i in lines:
i=i.split(" ")
for j in order:
if j = a:
use function for processing data chunk a
elseif j = b:
use proper function for processing data type b
...
I don't know beforehand
how many lines I have.
Now you tell us :-(
sorry
then loop order=[a,b,e,d...] for each line
What has a loop order got to do with using a dict?
order of data chunks varies per file
Why bother, just have a list of lists and index on the position, or are
we talking at cross purposes?
Sorry for the amount of text below, I hope it clarifies

The length of the text chunks varies from a single character to a list

So what, you still don't need to chop the front from the list, just

I'd like to adapt the order in that the functions are applied, but how?

You mean create a list with the order=[a,b,e,d...]
if a in order:
f_vector_array(a, 3)
elseif b in order:
f_value(max_radius)
that would run the proper function, but not in the right order?
Again I've no idea what you're saying here.

enumerate takes a start argument so you shouldn't need the above line.
points is needed later on in the program and I don't know beforehand how

Now you tell us :-(

Please show us your code and exactly why it didn't work.

functions={
'a':f_number(num_vertex),
'b':f_vector_array(rel_vertex,v)
}
where rel_vertex is the list where to move the processed data to and v
the amount of text to chop of the front of the line. v is not known when
defining the dictionary. v comes from an other function
v=f_number(num_vertex) that also should live in the dict.
You don't need to specify the parameters in the dict, just give the
function name.
then loop order=[a,b,e,d...] for each line
What has a loop order got to do with using a dict?
I'm not absolutely sure what you're saying here, but would something
like the SortedList from
http://www.grantjenks.com/docs/sortedcontainers/ help?
Maybe this explains it better, assume the split input lines:
line1=[a,b,c,d,e,f,...]
line2=[a,b,c,d,e,f,...]
line3=[a,b,c,d,e,f,...]
...
line10=...
all data on position a should go to list a
a=[a1,a2,a3,...a_n]
b=[b1,b2,b3,...b_n]
c=[c1,c2,c3,...n_n]
etc.
this is what for example the function f_vector_array(a, 3) does.
Why bother, just have a list of lists and index on the position, or are
we talking at cross purposes?
All these lists have to be written to a single file, each list contains
10 items. Instead of keeping it all in memory I could write a1 to a
temp file A instead of putting it in a list first and b1 to a temp file
B etc. in the next loop a2 to file A, b2 to file B etc. When all lines
are processed combine the files A,B,C ... to a single file. Or is there
a more practical way? Speed is not important.
What is your definition of "combine the files A,B,C ... to a single file"?

[Tutor] Proxy for Python?
Hi i am totally new to this, i am not a coder and am lost. I have python working on just 1 of my instagram account right now and its working great but i have no proxy in and im afraid i will get kicked off from IG and i cannot loose this account. i am having the hardest time trying to put my newly purchased Proxy from Highproxies.com into the code. I have tried so many combos and it fails everytime i try loading. This is what i am entering proxy="http://183.172.92.206:22313";, All i was given from them was an option to use my proxy is the two choices of User & Password Authentication or IP Authentication Right now i have it on IP Authentication by imputing my actual IP address in one of there 3 IP fields and hit setup to activate. But nothing works. I have asked them but they have no idea. Can anyone please help me?

Re: [Tutor] Recommended Resurce or strategy for beginning students
Thanks Alan, David and Mike, Really appreciate those thoughts and ideas suggested.. I will check out the full video David...but the part I've looked at has some great food for thought..is extremely relevant.This quote from the description is very true: "showing them how to copy-paste a few example programs and change a few parameters is easy, but bridging from there to building substantial programs is a different game entirely. This talk is about how to teach programming successfully, through comprehensible *design recipes*, which anyone can follow " Is interesting also his reference to robotsthat we could spend a year using robots...but not really getting deep learning happening...which is what I was wondering too... I think initially I do have to start with some example programsand if nothing else try and get them inspired to go further Anyway thanks...is going to be quite an interesting journey of learning for both students and teacher this Semester! Will keep looking through the suggestions and resources mentioned.
