Print a dictionary into a table
提问by Tim
I have a dictionary:
我有一本字典：
dic={'Tim':3, 'Kate':2}
I would like to output it as:
我想将其输出为：
Name Age
Tim 3
Kate 2
Is it a good way to first convert them into a list of dictionaries,
首先将它们转换为字典列表的好方法，
lst = [{'Name':'Tim', 'Age':3}, {'Name':'Kate', 'Age':2}]
and then write them into a table, by the method in https://stackoverflow.com/a/10373268/156458?
然后通过https://stackoverflow.com/a/10373268/156458中的方法将它们写入表格？
Or is there a way better in some sense?
或者在某种意义上有更好的方法吗？

Well, you don't have to convert it in a dictionary, you can directly:
好吧，你不必在字典中转换它，你可以直接：
print('Name Age')
for name, age in dic.items():
print('{} {}'.format(name, age))
回答by Bhargav Rao
You can do it directly as in
你可以直接做
>>> print("Name\tAge")
Name Age
>>> for i in dic:
... print("{}\t{}".format(i,dic[i]))
...
Tim 3
Kate 2
>>>
It displays even better if executed as a script
如果作为脚本执行，它会显示得更好
Name Age
Tim 3
Kate 2
And for the other representation
而对于其他表示
lst = [{'Name':'Tim', 'Age':3}, {'Name':'Kate', 'Age':2}]
print("Name\tAge")
for i in lst:
print("{}\t{}".format(i['Name'],i['Age']))
And for your final question - Is it a good way to first convert them into a list of dictionariesAnswer is No, A dictionary is hashed and provides faster access than lists
对于您的最后一个问题 -首先将它们转换为字典列表是一种好方法吗答案是否定的，字典经过哈希处理并提供比列表更快的访问

You could use pandas.
你可以使用熊猫。
In [15]: import pandas as pd
In [16]: df = pd.DataFrame({'Tim':3, 'Kate':2}.items(), columns=["name", "age"])
In [17]: df
Out[17]:
name age
0 Tim 3
1 Kate 2

Iterate dictionary and print every item.
迭代字典并打印每个项目。
Demo:
演示：
>>> dic = {'Tim':3, 'Kate':2}
>>> print "Name\tAge"
Name Age
>>> for i in dic.items():
... print "%s\t%s"%(i[0], i[1])
...
Tim 3
Kate 2
>>>
By CSV module
通过 CSV 模块
>>> import csv
>>> dic = {'Tim':3, 'Kate':2}
>>> with open("output.csv", 'wb') as fp:
... root = csv.writer(fp, delimiter='\t')
... root.writerow(["Name", "Age"])
... for i,j in dic.items():
... root.writerow([i, j])
...
>>>
Output: output.csv file content
输出：output.csv 文件内容
Name Age
Tim 3
Kate 2
We can use root.writerows(dic.items())also
我们可以用root.writerows(dic.items())同样
回答by vardos
You can do it this way,
你可以这样做，
format = "{:<10}{:<10}"
print format.format("Name","Age")
for name,age in dic.iteritems():
print format.format(name,age)
I have written a simple library to pretty print dictionary as a table https://github.com/varadchoudhari/Neat-Dictionarywhich uses a similar implementation
我写了一个简单的库来漂亮地打印字典作为表格 https://github.com/varadchoudhari/Neat-Dictionary使用类似的实现
