The following example shows various indentation errors:
\begin{verbatim}
- def perm(l): # error: first line indented
- for i in range(len(l)): # error: not indented
- s = l[:i] + l[i+1:]
- p = perm(l[:i] + l[i+1:]) # error: unexpected indent
- for x in p:
- r.append(l[i:i+1] + x)
- return r # error: inconsistent dedent
+ def perm(l): # error: first line indented
+for i in range(len(l)): # error: not indented
+ s = l[:i] + l[i+1:]
+ p = perm(l[:i] + l[i+1:]) # error: unexpected indent
+ for x in p:
+ r.append(l[i:i+1] + x)
+ return r # error: inconsistent dedent
\end{verbatim}
(Actually, the first three errors are detected by the parser; only the
\production{shortstringchar}
{<any ASCII character except "\e" or newline or the quote>}
\production{longstringchar}
- {<any ASCII characteru except "\e">}
+ {<any ASCII character except "\e">}
\production{escapeseq}
{"\e" <any ASCII character>}
\end{productionlist}
