Question

到目前为止，我的python代码是：

list=("Member ID, Surname, Year joined, Nights booked, Membership status, Points balance")
f = open("SampleData2017.txt")
print(list)
for surname in f.readlines():
   print(surname)

然而，当我运行它时，项目只用逗号分隔，而不是在每个副标题下

我希望它看起来像：

MemberID  Surname  Year  joined Membershipstatus  Nightsbooked  Points balance
Gri33415 Griffiths    2015         Gold               35          40000

Smi22316  Smith       2016        Silver              3            7500

我该如何解决这个问题？请尽可能简单

Answer 1

听起来你有一个标题列表，还有一个表格，其中包含你从SampleData2017.txt提取的数据。我使用了一个名为tabulate的第三方模块，因为它让我不必为简单的任务编写一堆代码。

在命令行上使用pip从pypi安装它。

$ pip install tabulate

或在Python3上

$ pip3 install tabulate

然后编写代码：

import tabulate

headers = map(str.strip, "Member ID, Surname, Year joined, Nights booked, Membership status, Points balance".split(","))
# or just format it yourself:
headers = ("Member ID", "Surname", "Year joined", "Nights booked",
           "Membership status", "Points balance")

with open("SampleData2017.txt") as f:
    # you never say how each row is split into fields, so I'm assuming here
    # that it's comma-separated and calling str.split(",") on each
    table = tabulate.tabulate((line.split(",") for line in f), headers=headers)

在此处使用我的示例数据，输出为：

>>> headers = ("one", "two", "three")
>>> data = [(1, 2, 3), (4, 5, 6), (7, 8, 9)]

>>> print(tabulate.tabulate(data, headers=headers))
  one    two    three
-----  -----  -------
    1      2        3
    4      5        6
    7      8        9

我猜你可以使用csv模块内置的python来实现你想要的东西

编辑1：

Observe标头最初分配为字符串，然后转换为列表

添加了对每个项目的信息，以便了解如何实现这一目标，但绝对不是您想要的精确对齐方式。

import csv
headers="Member ID, Surname, Year joined, Nights booked, Membership status, Points balance"
headers = headers.split(',')

print ('\t'.join(x.ljust(5) for x in headers))

with open('WorkingDirectory\stars.csv', 'r') as mycsv:
    rows = csv.reader(mycsv)
    for row in rows:
        print ('\t'.join(x.ljust(15) for x in row))

原始答案：

import csv

headers=["Member ID, Surname, Year joined, Nights booked, Membership status, Points balance"]

print ('\t'.join(headers))

with open('SampleData2017.txt', 'r') as mycsv:
    rows = csv.reader(mycsv)
    for row in rows:
        print ('\t'.join(row))

输出：

Member ID, Surname, Year joined, Nights booked, Membership status, Points balance
Gri33415    Griffiths   2015    Gold    35  40000
Smi22316    Smith   2016    Silver  3   7500
