EasyGraphLib 0.3.5

Python library for creating graphs, trees, and gemini structures.

EasyGraphLib

This is a simple package for working with graphs in Python 3.

Tasks:

• Add weighted graph.
• Add unweighted graph.
• Add tree's.

"class weighted_graph" methods:

• add_node("node name", "connect or connections", "values for con/con's") - This method create Node with connections, and Nodes for connections.

• add_connections("node name", "connection or connections", "values for con/con's") - This method adding connections to Node, and create new Nodes for connections.

• update_connection("node name", "connection", "value") - This method update weight for connection.

• remove_node("node name") - Remove node with connections.

• remove_connection("node name", "connection") - Remove connection from node.

• compile_graph() - Compile EasyGraphLib struct.

• find_tnw_d("EasyGraphLib struct") - Dijkstra algorythm.

  import easygraphlib as egl
  
  wg = egl.weighted_graph()
  
  wg.add_node("start", ("a", "b"), (6,2))
  wg.add_connections("start", ("c"), (3))
  wg.add_connections("c", ("a", "fin"), (2, 2))
  wg.add_connections("a", ("fin"), (3))
  wg.add_connections("b", ("a", "fin"), (3, 5))
  wg.update_connection("start", "c", (4))
  wg.update_connection("a", ("fin"), (1))
  
  input_graph = wg.compile_graph()
  print(input_graph)
  

"class unweighted_graph" methods:

• add_node("node name", "value", "connections", "auto create node flag True/False") - This method create Node with connections, and Nodes for connections.

• add_connections("node name", "connection or connections", "auto create node flag True/False") - This method adding connections to Node, and create new Nodes for connections.

• update_value("node name", "value") - Update value for Node.

• remove_node("node name") - Remove node with connections.

• remove_connection("node name", "connection") - remove connection from node.

• get_graph()

• wide_search("node name", "value", "condition")

  import easygraphlib as egl
  
  uwg = egl.unweighted_graph()
  
  uwg.add_node("me", False, ("Patrick", "Carry", "Josh"))
  uwg.add_node("Joseph", False, ("Lora"))
  uwg.add_connections("Patrick", ("Henry", "July", "me"))
  
  print(uwg.get_graph())
  
  uwg.add_connections("me", ("Henry", "Harry"))
  uwg.add_connections("Patrick", "Henry")
  print(uwg.get_graph())
