The if-elif block are empty. Python expects a sentence after the conditions.

If you want to have an empty block you can use the keyword pass:

if (...):
    pass
elif (...):
    pass

Note: Comments #... are ommited, and not considered as statements.

You don't have any code (just a comment) after the if statement where the error occurs.

If you add pass wherever you don't have code (just a comment), things should start to work.

no wonder, there's nothing between if and elif:

                if(L==0):   
                elif(L==1):

this is a syntax error.

you can put a pass in between, if you don't care about that branch:

                if(L==0):  
                  pass 
                elif(L==1):
                  pass
