problem code: ZCO12001

try:

maxc=0
pos1=0
pos2=0

for i in range(0,n):

    if(l[i]==1):

            pos1+=1
            if(c>maxc):

    elif(l[i]==2):
        c-=1
        length+=1
        l1.pop()
        if maxlength<length:
            maxlength=length
            maxpos2=pos2
print(maxc,end=" ")
print(maxpos1,end=" ")
print(maxlength,end=" ")
print(maxpos2,end=" ")

except:
pass

As you are using try except, you won’t know whether it is wrong answer or run time error.
Try block catches the error and starts running from except block. So, till then whatever is printed(even if nothing is printed), that wont match the expected output.

If I ruled the world, everyone who recommended using try … except blocks to “fix” runtime errors in Python would be banned from using their computer for a month :slight_smile:

Edit:

Please Like @vasu_vg’s post above rather than mine, as he actually explains why it’s bad :slight_smile:

Edit2:

Oh, great - now I’ve bumped this ancient thread to the top XD Soz!
