我想在行中打印表格数据，但它在列中打印

Question

这是我尝试的

for book in books:
print (tabulate(book, headers=["ID", "Title", "Author", "Pub_year", "available", "Shelf Place"]))

输出为

Answer 1

您没有显示有问题的output(注释中的文本无法读取)。你没有显示你在books中有什么，所以我猜所有的问题是tabulate需要行列表(每行都必须是项目列表)，但你发送单行，它线程这个列表中的每个字符串作为项目列表(所以它将每个字符作为分隔项)。

如果你想显示所有的书，那么你应该直接使用books而不是循环使用book

如果你想在单独的表中显示每个book，那么使用list[book]而不是book

from tabulate import tabulate
books = [
['1','Title 1','Author 1','2009', True, '9.99'],
['2','Title 2','Author 2','2010', True, '19.99'],
['3','Title 3','Author 3','2011', True, '29.99'],
]
print(tabulate(books, headers=["ID", "Title", "Author", "Pub_year", "available", "Shelf Place"]))
print('=================')
for book in books:
print(tabulate([book], headers=["ID", "Title", "Author", "Pub_year", "available", "Shelf Place"]))
print('=================')

结果:

ID  Title    Author      Pub_year  available      Shelf Place
----  -------  --------  ----------  -----------  -------------
1  Title 1  Author 1        2009  True                  9.99
2  Title 2  Author 2        2010  True                 19.99
3  Title 3  Author 3        2011  True                 29.99
=================
ID  Title    Author      Pub_year  available      Shelf Place
----  -------  --------  ----------  -----------  -------------
1  Title 1  Author 1        2009  True                  9.99
=================
ID  Title    Author      Pub_year  available      Shelf Place

2  Title 2  Author 2        2010  True                 19.99

3  Title 3  Author 3        2011  True                 29.99
=================
