Hi all, I have written a Link list implementation in Python (Although it's not needed with Lists and Dictionaries present. I tried it just for the kicks !). Anyway here is the code -
# Creating a class comprising of node in Link List. class linklist: def __init__(self, data=None,link=None): self.data = data self.link = link def __str__(self): return str(self.data) def printing(node): print "-"*80 print ("[data][link] ---> [data][link] and so on till the end") print "-"*80 while 1: if node.link: print node.data, node.link,"--->", node = node.link else: # Printing the last node and exiting. print node.data, node.link print ("All nodes printed") break def assigning(): global node1, node2, node3, node4 node1 = linklist([raw_input("Enter name: "), raw_input("Enter address: ")]) node2 = linklist([raw_input("Enter name: "), raw_input("Enter address: ")]) node3 = linklist([raw_input("Enter name: "), raw_input("Enter address: ")]) node4 = linklist([raw_input("Enter name: "), raw_input("Enter address: ")]) # Checking to see if all the node.data are getting populated. print node1 print node2 print node3 print node4 print linking() def linking(): node1.link = node2 node2.link = node3 node3.link = node4 # Passing the node1 to the print function so that it prints the rest of the nodes using the links. printing(node1) if __name__ == "__main__": assigning() Doubt - Now, Here I needed only 4 nodes. But what if I need more nodes. Is there any way to create the number of nodes at runtime. Since I plan to 'import' this module later. I wouldn't know how many nodes I need even before executing it. So, my doubt is - Is there any way to create 'n' number of object (here nodes) at runtime ? Any general criticisms about the code are also welcome... -- http://mail.python.org/mailman/listinfo/python-list
