Arranging problems so they will return side by side-CodePudding

For this project, I am trying to arrange the input from this function:

arithmetic_arranger(["32   8", "1 - 3801", "9999   9999", "523 - 49"])

So it looks like this:

  32         1      9999      523
   8    - 3801      9999    -  49
----    ------    ------    -----
  40     -3800     19998      474

There are four spaces in between each problem. By my results keep printing like this:

   32
  698
-----
  730,  3801
-    2
------
  3799,  45
  43
----
  88,  123
   49
-----
  172,

This is my code:

def arth(x, solve):
    fnlStr = ""
    for item in x:
        arth = item.split()
        val1 = int(arth[0])
        val2 = int(arth[2])
        len1 = len(arth[0])
        len2 = len(arth[2])

        if arth[1] == " ":
            sum = val1   val2
        else:
            sum = val1 - val2

        if(len1 > len2):
            dash = len1   2
        else:
            dash = len2   2

        def strCrt(x, y, s):
            return(x.ljust(y, s))
        
        String = ""
        numL1 = dash - len1
        numL2 = dash - (len2   1)
        numL3 = dash - len(str(sum))

        lineStr = strCrt(String, dash, "-")
        spaceL1 = strCrt(String, numL1, " ")
        spaceL2 = strCrt(String, numL2, " ")
        spaceL3 = strCrt(String, numL3, " ")


        fnlStr  = (f"{spaceL1}{val1}\n{arth[1]}{spaceL2}{val2}\n{lineStr}\n{spaceL3}{sum},")
    return(fnlStr)  

print(arth(["32   698", "3801 - 2", "45   43", "123   49"], True))

The problem may start from how I return the string at the bottom, so I tried this:

        fnlArr.append(f"{spaceL1}{val1}\n{arth[1]}{spaceL2}{val2}\n{lineStr}\n{spaceL3}{sum},")
    return(fnlArr)
    

print(arth(["32   698", "3801 - 2", "45   43", "123   49"], True))

But that still gave me some problems, returning this:

['   32\n  698\n-----\n  730,', '  3801\n-    2\n------\n  3799,', '  45\n  43\n----\n  88,', '  123\n   49\n-----\n  172,']

How should I change up my code so it arranges the problems side by side and not below eachother or formatted wierd in a list? Any help would be greatly appriciated, i'm sorry for any simple errors in my code, I am very new. Thank you.

You can create a list where you put the split expression (using str.split(maxsplit=1)), the ----part and the result.

Then you can transpose this list (using zip(*...)) and print it line-by-line:

def arithmetic_arranger(exprs):
    out = []
    for e in exprs:
        e = e.split(maxsplit=1)
        max_len = len(max(e, key=len))
        out.append(
            [f"{ee:>{max_len}}" for ee in e   ["-" * max_len, eval("".join(e))]]
        )

    for row in zip(*out):
        print("   ".join(row))


arithmetic_arranger(["32   8", "1 - 3801", "9999   9999", "523 - 49"])

Prints:

 32        1     9999    523
  8   - 3801     9999   - 49
---   ------   ------   ----
 40    -3800    19998    474

for row in zip(*out):
    print("   ".join(row))
