Question

我有这个数据集，我需要对齐ID，Date和Title的列。我不确定如何对齐这些以及如何添加标题？我无法使用tabulate等任何第三方功能。有人可以告诉我如何做到这一点？我是初学者，只需要一些指导！

data_set = [['ID=j234hg\n'], ['Date=19 October 1969\n'], ['Title=court scene with cardinal richelieu\n'], ['ID=d45j5jkd\n'], ['Date=28 December 1969\n'], ['Title=THE ROYAL PHILHARMONIC ORCHESTRA GOES TO THE BATHROOM\n'], ['ID=s4k5jk\n'], ['Date=8 December 1970\n'], ['Title=crossing the atlantic on a tricycle\n'], ['ID=zd7u4h\n'], ['Date=19 October 1969\n'], ['Title=Bicycle Repair Man\n'], ['ID=f983\n'], ['Date=22 December 1970\n'], ['Title=Royal Episode 13 (or: The Queen Will Be Watching)\n'], ['ID=j8s74\n'], ['Date=15 September 1970\n'], ['Title=THE SEMAPHORE VERSION OF WUTHERING HEIGHTS\n'], ['ID=n4j6l3j\n'], ['Date=7 December 1972\n'], ['Title=Mr. Pither']]

for index,l in enumerate(data_set):
    column_name,value = l[0].split("=")
    if 'Title' == column_name:
        data_set[index]="=".join([column_name+value.title()])

print (data_set)

rows = [ data_set[i:i+3] for i in range(0,len(data_set), 3)]
print (sum(sorted(rows, key = lambda r:r[0][0]), []))

它需要看起来像这样：

#ID       Date              Title
#d45j5jkd 28 December 1969  The Royal Philharmonic Orchestra Goes To The Bathroom
#f983     22 December 1970  Royal Episode 13 (Or: The Queen Will Be Watching)

Answer 1

您可以使用Python3.x Format Specification Mini-Language对标题和data_set进行格式化和对齐。

不幸的是，data_set是list的子lists，因此我们需要Flatten list of lists开始有点混乱，然后在{{1}打印-loop使用named placeholders and string padding从展平列表中打印3个组：

for

输出：

data_set = [['ID=j234hg\n'], ['Date=19 October 1969\n'], ['Title=court scene with cardinal richelieu\n'], 
        ['ID=d45j5jkd\n'], ['Date=28 December 1969\n'], ['Title=THE ROYAL PHILHARMONIC ORCHESTRA GOES TO THE BATHROOM\n'], 
        ['ID=s4k5jk\n'], ['Date=8 December 1970\n'], ['Title=crossing the atlantic on a tricycle\n'], 
        ['ID=zd7u4h\n'], ['Date=19 October 1969\n'], ['Title=Bicycle Repair Man\n'], ['ID=f983\n'], 
        ['Date=22 December 1970\n'], ['Title=Royal Episode 13 (or: The Queen Will Be Watching)\n'], 
        ['ID=j8s74\n'], ['Date=15 September 1970\n'], ['Title=THE SEMAPHORE VERSION OF WUTHERING HEIGHTS\n'], 
        ['ID=n4j6l3j\n'], ['Date=7 December 1972\n'], ['Title=Mr. Pither']]

#First, flatten the list of lists to one list of strings
flist = [item for sublist in data_set for item in sublist]

print('{h1:10}{h2:20}{h3}'.format(h1='#ID', h2='Date', h3='Title'))
for i in range(0, len(flist), 3):
    print('{id:10}{date:20}{title}'   
                       .format(   
                               id=flist[i].strip('\n').split('=')[1],   
                               date=flist[i+1].strip('\n').split('=')[1],   
                               title=flist[i+2].strip('\n').split('=')[1])
                              )

如果它没有完全回答你的问题，请随意发表评论我道歉，因为它很乱，但它的确有效。我稍后会尝试清理它。与此同时，我希望它有所帮助。
