Gives Out Key Error = 0 When Using Insertion Sort In Python

in my lottery game i need to create 1000 players and each player has a number set which needs to be compared with a winning number set. all the numbers sets are from a barrel of 0-

Solution 1:

You are iterating over the dictionary with the wrong key.

Here the right code:

forkeyin players: 
    print(players[key]) 

For mappings (like dictionaries), .__iter__() should iterate over the keys. This means that if you put a dictionary directly into a for loop, Python will automatically call .__iter__() on that dictionary, and you’ll get an iterator over its keys.

Solution 2:

Note: I have not reviewed your sorting algorithm for correctness. This answer solely addresses the KeyError.

KeyError is raised because you are trying to look for a key in a dict that isn't there.

defgenerateID():
    ...
    for player_id inrange(1, 1001):  # Populates player IDs from 1, 2, 3...
        players[player_id] = ...

    for i inrange(len(players)):     # Searches player IDs from 0, 1, 2...print (players[i]) 

In general, just loop over players. Since it is a dictionary, you can use .items() to retrieve the keys and values:

defgenerateID():
    ...
    forid, player_list in players.items():
        print (player_list)
