Game of Life with file read for world generation. How to get file to display world properly?-CodePudding

Like the title says, I've being working on a variant of Conway's Game of Life in python that can read a "world" and generate some elements from a file and generate the starting world from that. However, in my code, the world is being displayed as

([['*', ' ', ' ', ' ', ' ', ' '], ['*', '*', ' '], ['*', '*', '*'], ['*', '*', '*', '*'], ['*', '*', '*', '*', '*'], ['*', '*', '*', '*', '*', '*'], ['*', '*', '*', '*', '*', '*', '*'], ['*', '*', '*', '*', '*', '*', '*', '*'], ['*', '*', '*', '*', '*', '*', '*', '*', '*'], ['*', '*', '*', '*', '*', '*', '*', '*', '*']], 10, 6)

When I am trying to get it to look like this as it is from the imported file.

*     
**

****

I have no clue on how to get this program to display it properly as I have tried to edit around the list variables, but nothing I am doing is actually doing anything, as it either displays it wrong or just gives me an error. Can anyone here point me in the right direction?

Thank you for the help, and please let me know if there's any additional info I should provide

def main():
    world = []
    while True:
        try:
            filename = input("Name of input file: ")
            for aLine in open(filename,"r"):
                world.append(list(aLine[:-1]))
            if world:
                maxRows = len(world)
                maxColumns = len(world[0])
                return world, maxRows, maxColumns
            print("The file %s" %(filename), "is empty.")
        except IOError:
            print("Problem reading from file %s" %(filename))

print(main())

Use str.join and/or the sep parameter to print():

>>> world, rows, columns = ([['*', ' ', ' ', ' ', ' ', ' '], ['*', '*', ' '], ['*', '*', '*'], ['*', '*', '*', '*'], ['*', '*', '*', '*', '*'], ['*', '*', '*', '*', '*', '*'], ['*', '*', '*', '*', '*', '*', '*'], ['*', '*', '*', '*', '*', '*', '*', '*'], ['*', '*', '*', '*', '*', '*', '*', '*', '*'], ['*', '*', '*', '*', '*', '*', '*', '*', '*']], 10, 6)
>>> print(*(''.join(row) for row in world), sep='\n')
*

You probably want something like this.

def main():
    # get the file to read
    filename = input("Name of input file: ")

    # open, read, and close the file
    with open(filename, "r") as f:
        world = [list(line[:-1]) for line in f]
    
    # get derived information
    rows = len(world)
    columns = max([len(i) for i in world])
    world_printable = '\n'.join([''.join(i) for i in world])

    return world, rows, columns, world_printable
    

world, rows, columns, world_printable = main()
print(world_printable)
