Python 我需要返回前20个字数，但是我'；我只能返回第一个字数，不能返回其余的。如果有人能帮忙的话

我需要返回前20个字数。但是，我只能返回第一个字数，不能返回其余的

def print_top(all_text, top = 20):
    dict2 ={}
    word_d =  word_dict(all_text)
    items = sorted(word_d.items(), key=get_count, reverse=True)
    for amounts in items[:20]:
        dict2 = (amounts[0], amounts[1])
        return dict2

这应该会有所帮助。您的return语句在循环中。因此，在第一个元素之后返回值。请尝试下面的代码片段

def print_top(all_text, top = 20):
    word_d =  word_dict(all_text)
    items = sorted(word_d.items(), key=get_count, reverse=True)
    dict2 = {}  #Output Dict
    for amounts in items[:20]:
        dict2[amounts[0]] = amounts[1]
    return dict2  #-- > Outside the loop

显示为什么您的结果只返回1个

您可以使用1-liner完成您的任务，它是：

例如：

from collections import Counter
from pprint import pprint

data = """Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod 
tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos 
et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata 
sanctus est Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet, consetetur sadipscing

Duis autem vel eum iriure dolor in hendrerit in vulputate velit esse molestie consequat,

facilisi. Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy 
nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat."""

words = [x.strip(",.!?") for x in data.split() if x.rstrip()]

dic = Counter(words).most_common(20)

pprint(dic)

输出：

[('et', 14),
 ('dolor', 8),
 ('Lorem', 7),
 ('ipsum', 7),
 ('sit', 7),
 ('amet', 7),
 ('sed', 7),
 ('diam', 7),

 ('ut', 4),
 ('magna', 4),

 ('elitr', 3),
 ('nonumy', 3),
 ('eirmod', 3),
