why does it show a syntax error?

Question

File "..\Playground\", line 17
elif ((l.index(l[x]))+I)>+26 :
^
SyntaxError: invalid syntax ,,,,,,,,,,,,, sry i made a mistake writing the error

part of the code is :
if l[x] in ast:
n=k[I]
if n==1 :
if ((l.index(l[x]))+I)<26 :
cp0.insert(ast.index(l[x]),l[x+I])
cp0.pop((ast.index(l[x])+1)
elif ((l.index(l[x]))+I)>26 :
cp0.insert(ast.index(l[x]),l[I+l.index(l[x])-26])
cp0.pop(ast.index(l[x])+1)
else :
None

and it shows error :
File "..\Playground\", line 17
elif ((l.index(l[x]))+I)>26 :
^
SyntaxError: invalid syntax
