我想根据长度对列表中的单词进行排序。
测试用例为{'cat','jump','blue','balloon'}
当运行此方法时,它将按以下方式打印:
{'balloon','jump','blue','balloon'}
我遇到的另一个问题是我们使用的python类型工作正常,但是当我尝试在Python 3.5.2 shell中运行.py时,它会出现错误。
我主要只需要知道我做错了什么,以及我可以做些什么来修复它以便它起作用。任何帮助表示赞赏!
可以找到.py文件here:
def wordSort():
words = []
minimum = 'NaN'
index = 0
x = 0
y = 0
z = 1
#How many words to be entered
length = input('How many words would you like to enter? ')
#Put words in the number of times you entered previously
while not z >= length + 1:
words.append(raw_input('Enter word #' + str(z) + ': '))
z += 1
while x < length:
minimum = words[x]
#Goes through the list and finds a smaller word
while y < length:
if len(words[y]) < len(minimum):
minimum = words[y]
index = y
y += 1
words[index] = words[x]
words[x] = minimum
x += 1
print words

import { Injectable } from '@angular/core';
import { AuthService } from './auth.service';
import { Http, Headers, RequestOptions, Response } from '@angular/http';
@Injectable()
export class UserService {
BASE_URL: string = 'http://localhost:3000';
constructor(
private http: Http,
private authService: AuthService
) { }
get(id) {
let headers = new Headers({ 'Authorization': 'JWT ' + this.authService.token });
let options = new RequestOptions({ headers: headers });
return this.http.get(this.BASE_URL + '/users/' + id, options)
.map((res) => res.json());
}
是Python 3.5中的一个函数,需要用作print
。详细了解here 给定一个单词列表,可以使用sorted根据字符串的长度对它们进行排序:
print(words)

试试这个。它将根据字符串的长度按升序对列表进行排序
list_name.sort(key=len)
按降序排列,
list_name.sort(key=len,reverse=True)
