Split a string into smaller strings with conditions

I have a string that is constantly getting longer for each iteration (moves in a game). I want to print this string to my window and the window space is 75 characters in a row, then I need to switch line.

Condition: The list contains the move numbers and corresponding moves for each side:

my_str = '1.move movee 2.mov moveee 3.mo mover'

The split can't be in the middle of a move so it needs to happen between the moves:

my_str1 = '1.move movee 2.mov moveee'
my_str2 = '3.mo mover'

Is there a nice way of doing this without lots and lots of loops and if statements?

Here's something that works by first extracting each move (might be valuable to you in itself) and then prints the list of moves with line length logic:

import re

my_str = '1.move movee 2.mov moveee 3.mo mover 4.move movee 5.mov moveee 6.mo mover 7.move movee 8.mov moveee 9.mo mover 10.move movee 11.mov moveee 12.mo mover 13.move movee 14.mov moveee 15.mo mover'

moves = re.findall(r"\S+\s+\S+", my_str)

line = ''
for move in moves:
    if len(line) + len(move) + 1 > 75:
        print(line)
        line = move
    elif line:
        line += ' ' + move
    else:
        line = move
if (line):
    print(line)

Result:

1.move movee 2.mov moveee 3.mo mover 4.move movee 5.mov moveee 6.mo mover
7.move movee 8.mov moveee 9.mo mover 10.move movee 11.mov moveee
12.mo mover 13.move movee 14.mov moveee 15.mo mover

Try storing your moves in a list.

Adding a move:

moves.append("move movee")

Reading moves:

moves[0] # First move
moves[1] # Second move
moves[-1] # Last move
moves[-2] # Second to last move

Iterating through moves:

for move in moves:
    print(move)

Here is a function that will print your moves:

moves = ["nassssssssssss ssssss sssssssssssssss", "nasdasdasda sdasdas", "eas dasdasdasd", "easdasdasda sdasdsad", "sasda dsasdasd"]

def formatMoves(moves, screenwidth=75):
    out = ""
    for i in range(len(moves)):
        move = moves[i]

        if len(out) == 0 or len(out.split("\n")[-1]) == 0:
            # Start a new line
            out += f"{str(i+1)}.{move}"
        
        elif len(out.split("\n")[-1]) + len(str(i+1)) + 2 + len(move) <= screenwidth:
            # Continue a line
            out += f" {str(i+1)}.{move}"
            
        else:
            # Start a new line
            out += f"\n{str(i+1)}.{move}"
    return out

print("-"*75)
print(formatMoves(moves))

Output (the first line just shows it is 75 chars long):

---------------------------------------------------------------------------
1.nassssssssssss ssssss sssssssssssssss 2.nasdasdasda sdasdas
3.eas dasdasdasd 4.easdasdasda sdasdsad 5.sasda dsasdasd

Here is how you can use the end parameter of the print function:

my_str = '1.move movee 2.mov moveee 3.mo mover'

count = 0
length = len(my_str)

for i, v in enumerate(my_str):
    if i - 1 < length :
        if count >= 75 and my_str[i + 1].isdigit():
            count = 0
            s = '\n'
        else:
            count += 1
            s = ''
    print(v, end=s)

With end='' as a print parameter, when you proceed to print again, the output will be printed on the same line.

if count >= 75 and i == ' ':

tells python when to switch a line; when the number of characters reach 75, and the current character needs to be a ' ' so to not cut a move.
