python - file to dictionary:value is a dictionary where the key is repeated -


I open a file containing: 

  No transaction customer customer purchase Purchase ---- --------- ---- ---------- ------------- 1 09-04-2014 Barco Bama Potato: 2.67, sugar: 1.98, cereals: 5.99 crisps: 1.0 9 2 11-04-2014 Barcoba parsley: 0.76 grains: 3.22 3 11-04-2014 vladimirputin bread: 0.66, milk: 2.87, parsley: 1.33 >  
 and I would like the output dictionary like this:  
  {'milk': {'vladimirputin': 2.87}, 'grain': {'barcomba': 9.21 }, 'Roti': {'' '' potato ': {' barcomba ': 2.67},' sugar ': {' barcomba ': 1 9 8}, 'parsley': {'vladimirputin': 1.33,   
 I did this: for the line in the file  
  C = {} File = open (filename name, 'r'): if the line [0] .isdigit (): fields = line partition ()    
 
 
  c = {} f = open (fileNameStr): if not line [0] .isdigit (): continue the transaction, _date, customerId , PurchasePairs = line for pairs in purchase .split () pair.Split (','): productName, price = pair.split (':') if productName c: c [productName] [customerId] = float (price ) Else: c [productName]] = {CustomerId: float (price)}   
 You have a relationship Areas to be dealt: a client more than once buys the same time. Hope this code will help.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
