Python Error

[Wictorian]

while(true):
    for f in range(i-1):
        try:
            dList1[h].append(columnLists[f][20-i+f])
    if state == 1:
        i+=1
        if i == 20:
            state = 2
    elif state == 2:
        i -= 1
        if i == 0:
            state = 3
    elif state == 3:
        i += 1
        if i == 5:
            break
    h += 1

gives error 

if state == 1:                                                                                                            

    ^                                                                                                                         

IndentationError: unexpected unindent

@Wictorian except block is missing

Fighting my need to say "this is why I dislike Python!" and why we just need curly brackets

 

Indent means "a space created by pressing Tab", basically. Unindent is the opposite, the lack of such an indent.

Anything in the Try needs to be indented one Tab further. I think except is also needed.

 

I'm not a Python expert, so that may not all be 100% correct

wait, I just wanna continue the loop in case of expect.

 

if I write continue would it be ok?

Except block is missing, the boolean value should be capitalized as True, and if this is your entire code then the variables (state, i, dList1, columnList, h) all need to be defined

The code inside Try is already indented, he is just missing the Except and it thinks that the if statement should be intended when it doesn't have to be because it's continuing processing code in the same indentation as the Try.

try:   
	dList1[h].append(columnLists[f][20-i+f])
except: 
	pass

or just simply this without the try and except

dList1[h].append(columnLists[f][20-i+f])

Yes you can use "continue" inside the except block, but it isn't recommended if you're doing so to ignore errors, only if you expect a type of error to occur then you should specify which error to catch, though you can still do a continue statement without that if you want.

 

for f in range(i-1):
	try:
		dList1[h].append(columnLists[f][20-i+f])
	except:
		continue

 

Continue statements can only be valid if the "try" is inside a loop, which this one is, so it works

I wanted to ignore an error but I dont know if its true. Can you please check my latest thread?
