Arithmetic arranger problem

[choukri]

Hello i hope you are doing verry well,
i have a problem concerning the arrithmetic arranger problem in scientific computing with python . In fact, i have written my code in my own pyhton IDE on my computer and i have copied all the tests that are given the replit website to see if i have fully done the job. And when i test my code on my own IDE it works very well but when i paste my code in replit and test it on replit i have an issue with 2 tests wich are (test_arrangement, and test_solutions. The problem is that my code works very well on my own IDE .
Please help me, I would be very thankfull.
my code is as follows:

#function that detects the first space in a string
def detect_first_space(l):
    inter=0
    for i in l:
        if i==" ":
            inter=l.index(i)
            return inter;
        else:
            None;
#function that compares two strings and renturns the index of the longest string in inter in arithmetic_arranger
def compar_str(m):
    if len(m[0])>len(m[2]):
        return 0;
    else:
        return 2;






def arithmetic_arranger(problems,result=False):
    if not len(problems)<=5:
        return "Error: Too many problems."
    inter=[]
    r=""
    for i in problems:
        space_index=detect_first_space(i)
        inter.append([i[0:space_index],i[space_index+1],i[space_index+3:]])
    for j in inter:
        try :
            (int(j[0]) and int(j[2]))
        except:
            return "Error: Numbers must only contain digits."
        if not(j[1]=="+" or j[1]=="-" ):
            return "Error: Operator must be '+' or '-'."
        if not( len(j[0])<=4 and len(j[2])<=4):
            return "Error: Numbers cannot be more than four digits."
        j.append(compar_str(j))
    for j in inter:
        r+="  "
        if j[3]==0 :
            r=r+ j[0]
        else:
            r=r+" "*(len(j[2])-len(j[0]))
            r=r+ j[0]
        r+= "    "
    r+="\n"
    for j in inter :
        r=r+j[1]+" "
        if j[3]==0 :
            r=r+" "*(len(j[0])-len(j[2]))
            r=r+j[2]
        else:
            r=r+j[2]
        r=r+"    "
    r=r+"\n"
    for j in inter:
        r=r+"-"*(2+len(j[j[3]]))
        r=r+"    "
    if result==True:
        r=r+"\n"
        for j in inter:
            if j[1]=="+":
                x=int(j[0])+int(j[2])
            else:
                x=int(j[0])-int(j[2])
            x=str(x)
            if len(x)<(len(j[j[3]])+2):
                r=r+" "*(2+len(j[j[3]])-len(x))
                r=r+x
            else:
                r=r+x
            r=r+"    "
    return r
