Body
Here's 2 programs, one to create a dictionary, and the other to implement it, the first one being:- <pre><code> class dictionary: def _init_(self, pword=[]): self.word = pword def addWord(self, nword): l = len(self.word) bp = -1 for num in range(0,l): if self.word[num][0]==nword: return if self.word[num][0]>nword: bp = num break nl = [nword] self.word.append([]) if bp>=0: for num in range(l-1,bp+1,-1): self.word[num] = self.word[num-1] else: bp+=1 (self.word).insert(bp,nl) def addKey(self, nword,key): l = len(self.word) for num in self.word: if num[0]==nword: if num.count(key)==0: num.append(key) return print("'"+nword+"' was not found in the present dictionary\n") def display(self): if len(self.word)==0: print("Dictionary is currently Empty\n") return for num in self.word: for nw in num: print(nw+"\t") print("\n") </code></pre> And the other one is <pre><code>import file def main(): print("Running file") td = file.dictionary() td.addWord("A") td.addWord("B") td.addWord("C") print("Words added") td.addKey("A",1) td.addKey("A",2) td.addKey("B",3) td.addKey("C",1) td.addKey("C",3) print("Keys added") td.display() main() </code></pre> Both the programs compile without a problem But when i run the second one, i get the following error <pre><code>Running file Traceback (most recent call last): File "E:\Documents\Information Retrieval\ptrial.py", line 17, in <module> main() File "E:\Documents\Information Retrieval\ptrial.py", line 5, in main td.addWord("A") File "E:\Documents\Information Retrieval\file.py", line 6, in addWord l = len(self.word) AttributeError: 'dictionary' object has no attribute 'word'** </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
