Next, inside the else block, declare a variable called key_char and assign it the value of key at the index key_index mod(%) the length of key.
You should declare a variable called key_char at the beginning of your else clause body.
const commentless_code = __helpers.python.removeComments(code);
const {block_body} = __helpers.python.getBlock(commentless_code, "else");
assert(block_body.match(/^\s*key_char\s*=/));
You should assign key[key_index % len(key)] to your key_char variable.
const commentless_code = __helpers.python.removeComments(code);
const {block_body} = __helpers.python.getBlock(commentless_code, "else");
assert(block_body.match(/key_char\s*=\s*key\s*\[\s*key_index\s*%\s*len\s*\(\s*key\s*\)\s*\]/));
Your code contains invalid syntax and/or invalid indentation.
