Question

我正在尝试提出一个能够接收字符串并将其拆分为n个字符的消息的代码。每条消息不能超过n个字符，但不能超过n个字符，因为单词不应拆分。例如，“这是示例消息”，n = 10。此代码将返回 '这是一' '例' “消息”

关于如何解决这个问题的任何建议？

const searchingFor = (term) => {
    return (x) => {
        return x.tecnologia.toLowerCase().includes(term.toLowerCase()) || !term;
    }
}


class FilterClass extends React.Component {
    constructor(props) {
        super(props);
        this.state = {
            empresas: [
                {
                    empresa: "Daniel",
                    tecnologia: "React",
                    clientes: ["sodimac", "ripley", "paris"],
                    experiencia: "5 años",
                    id: 1

                },
                {
                    empresa: "Juan",
                    tecnologia: "React",
                    clientes: ["Falabella", "ripley", "ikea"],
                    experiencia: "3 años",
                    id: 2

                },
                {
                    empresa: "David",
                    tecnologia: "Angular",
                    clientes: ["Falabella", "ripley", "ikea"],
                    experiencia: "3 años",
                    id: 2

                },
                {
                    empresa: "Carlos",
                    tecnologia: "Vue",
                    clientes: ["Copec", "Wallmark", "Unimark"],
                    experiencia: "6 años",
                    id: 3

                }
            ],
            term: ''
        }

        this.searchHandler = this.searchHandler.bind(this);

    }

    searchHandler(event) {
        this.setState({ term: event.target.value })
    }

    render() {

        const {term, empresas} = this.state;

        return (
            <div>
                <form className="container--flex-center">
                    <input type="text" onChange={this.searchHandler} value={term} />
                </form>
                {empresas.filter(searchingFor(term)).map(item =>
                    <FilterComponent
                        empresa={item.empresa}
                        tecnologia={item.tecnologia}
                        clientes={item.clientes}
                        experiencia={item.experiencia}
                        key={item.id}
                    />
                )}

            </div>
        )
    }


}

export default FilterClass;

x是我认为需要的消息数。有人可以向我解释如何完成我的代码吗？

Answer 1

这就是textwrap库的作用。

>>> from textwrap import wrap
>>> print(wrap('This is an example message', 10))
['This is an', 'example', 'message']

使用python将字符串分割成段
