从 .txt 文件读取并以 table 格式打印

Question

那么我该如何操作一段代码，以便它从 .txt 文件中读取数据，并以 table 格式打印数据，标题如 'Resident Number' 'Rent date' 'Price'等等？文件的名称是 Residents.txt

到目前为止，我有这个

file = open('Residents.txt','r')
For line in file:
    SplitFile = line.split (',')

这是 .txt 文件-
R1,21/09/2015,C1,440,P,0
R2,21/09/2015,C3,290,A,290
R3,21/09/2015,C4,730,N,0
R4,22/09/2015,C5,180,A,180
R5,22/09/2015,C6,815,A,400
R6,23/09/2015,C7,970,N,0
R7,23/09/2015,C8,1050,P,0
R8,23/09/2015,C9,370,A,200
R9,25/09/2015,C10,480,A,250
R10,25/09/2015,C11,330,A,330

这是 .txt 文件中每一列的表示-

line.split[0] = Resident Number      
line.split[1] = Rent Date       
line.split[2] = Customer number        
line.split[3] = Rent amount         
line.split[4] = (A means Accepted)(N means not accepted)(P means Pending)          
line.split[5] = Amount paid

请注意-
如果支付的金额等于租金金额，则居民数据不应显示在 table
中如果状态为 N 或 P，则居民数据也不应显示在 table

中

如何显示标题为 'Resident number' 'Rent date' 'Customer number' 'Rent amount' 'Amount outstanding'- 的 table（不导入模块）未付金额只是租金金额 - 从该行支付的金额。另外，我怎样才能打印出未结金额的最终总额（所有尚未付款且状态为 'A' 的人的总和）

Python 3.5

谢谢

编辑

for i, word in enumerate(line):
        if i == 4 :  # We don't print the status
            continue
        elif i == 2:
            continue
        print(word.ljust(len(headers[i - (i > 4)(i > 2)])), end="    " * ((i - (i > 4)(i > 2)) != len(headers) - 1))
print()

line = line.strip().split(",")
    subtotal = int(line[3]) - int(line[5])
    line.append(str(subtotal))
    if line[5] == line[3] or line[4] in ("N", "E"):
        continue
    total += subtotal

Answer 1

您可以使用表格

https://pypi.python.org/pypi/tabulate

来自 link：

from tabulate import tabulate

table = [["Sun",696000,1989100000],["Earth",6371,5973.6],
        ["Moon",1737,73.5],["Mars",3390,641.85]]
print tabulate(table)

输出：

-----  ------  -------------
Sun    696000     1.9891e+09
Earth    6371  5973.6
Moon     1737    73.5
Mars     3390   641.85
-----  ------  -------------

你可以这样做：

headers = ["Resident Number", "Rent Date", "Customer number", "Rent ammount", "Ammount paid", "Outstanding Ammount"]

print("    ".join(headers))
for line in open("test.txt", "r"):
    line = line.strip().split(",")
    line.append(str(int(line[3]) - int(line[5])))
    if line[5] == line[3] or line[4] in ("N", "P"):
        continue
    for i, word in enumerate(line):
        if i == 4:
            continue
        print(word.ljust(len(headers[i - (i > 4)])), end="    " * ((i - (i > 4)) != len(headers) - 1))
    print()

输出：

Resident Number    Rent Date    Customer number    Rent ammount    Ammount paid    Outstanding Ammount
R5                 22/09/2015    C6                 815             400             415                
R8                 23/09/2015    C9                 370             200             170                
R9                 25/09/2015    C10                480             250             230
