我在Jinja中设置了一个for循环，for循环通过eg: ['abc', 'def']项目列表进行迭代
现在，当我尝试使用eg: {{ [i]["letters"] }}时
Jinja数着['']例如：还给我：['abc']，我不想要。。
现在我该如何摆脱那些['']
这是我的for循环位：

我找到了一个变通办法。。
从API请求，通过后端(Flask->Python(，我将所有标题/overviews/poster_path附加到3个数组中，并在这些数组中传递API请求本身的长度，使用len((。
然后在index.html上，通过Jinja，我为loop设置了一个来迭代API请求的长度范围，并使用索引，将我传入的数组的索引设置为API请求长度的当前值，boom完成！！
简单！！
