大家。我是Python新手,急需一些帮助。我试图计算几个列表中的唯一值,然后将输出并排打印为列。我可以使用集合来计算它们。但是,我不知道如何并排打印它们。是否有任何pythonic方法可以将它们并排或并排显示为列?
我试过以下但无济于事。非常感谢任何帮助。
print(str(parsed_list(a)) + str(parsed_list(b)) + str(parsed_list(b)))
NoneNoneNone
我的样本可测试代码(Python3):
import collections, operator
a = ['Black Cat', 'Black Dog', 'Black Mouse']
b = ['Bird', 'Bird', 'Parrot']
c = ['Eagle', 'Eagle', 'Eagle', 'Hawk']
def parsed_list(list):
y = collections.Counter(list)
for k, v in sorted(y.items(), key=operator.itemgetter(1), reverse=True):
z = (str(k).ljust(12, ' ') + (str(v)))
print(z)
print('Column1 Column2 Column3')
print('-' * 45)
parsed_list(a)
parsed_list(b)
parsed_list(c)
电流:
Column1 Column2 Column3
---------------------------------------------
Black Cat 1
Black Dog 1
Black Mouse 1
Bird 2
Parrot 1
Eagle 3
Hawk 1
期望的输出:
Column1 Column2 Column3
----------------------------------------
Black Cat 1 Bird 2 Eagle 3
Black Dog 1 Parrot 1 Hawk 1
Black Mouse 1

依赖于tabulate module:
package xyz.adamstephenson.android.myapplication;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.content.Intent;
import static
xyz.adamstephenson.android.myapplication.R.layout.activity_main;
public class MyActivity extends Activity {
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(activity_main);
final Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Log.d("button", "This is my message");
}
});
}
}

from collections import Counter
from itertools import zip_longest
a = ['Black Cat', 'Black Dog', 'Black Mouse']
b = ['Bird', 'Bird', 'Parrot']
c = ['Eagle', 'Eagle', 'Eagle', 'Hawk']
def parse(lst):
c = Counter(lst)
r = []
for s, cnt in c.most_common():
r += ['%12s%3i' % (s, cnt)]
return r
for cols in zip_longest(parse(a), parse(b), parse(c), fillvalue=15*' '):
print(' '.join(cols))
这会产生:
Black Cat 1 Bird 2 Eagle 3
Black Mouse 1 Parrot 1 Hawk 1
Black Dog 1

我确定您可以手动构建自己的库,但Python似乎有一个内置于字符串类型的格式方法,可以很好地满足您的需要。
以前帖子的link可以帮到你!试一试!
