python - 字符串输出格式

Question

我的代码:

infile = open("table1.txt", "r")
a_list = infile.read().split("\n")
infile.close()

for pass_num in range(len(a_list)-1, 0, -1):

    for i in range(0, pass_num):

        if int(a_list[i].split(",")[1].strip()) > int(a_list[i+1].split(",")[1].strip()):
        a_list[i], a_list[i+1] = a_list[i+1], a_list[i]


        if (int(a_list[i].split(",")[1].strip()) == int(a_list[i+1].split(",")[1].strip())) and ((int(a_list[i].split(",")[2]) - int(a_list[i].split(",")[3].strip())) > (int(a_list[i+1].split(",")[2].strip()) - int(a_list[i+1].split(",")[3].strip()))):
        a_list[i], a_list[i+1] = a_list[i+1], a_list[i]


        if (int(a_list[i].split(",")[1].strip()) == int(a_list[i+1].split(",")[1].strip())) and ((int(a_list[i].split(",")[2]) - int(a_list[i].split(",")[3].strip())) == (int(a_list[i+1].split(",")[2].strip()) - int(a_list[i+1].split(",")[3].strip()))):
            if (int(a_list[i].split(",")[2])) > int(a_list[i+1].split(",")[2]):
                a_list[i], a_list[i+1] = a_list[i+1], a_list[i]

a_list.reverse()

print("    Team" + " "*(30-len("    Team")) + "Points" + " "*2 + "Diff" + " "*4 + "Goals")

for i in range(len(a_list)):

    team = a_list[i].split(",")[0]
    points = a_list[i].split(",")[1]
    goalfor = int(a_list[i].split(",")[2].strip())
    goalagainst = int(a_list[i].split(",")[3].strip())
    diff = goalfor - goalagainst

print(str(i+1).rjust(2) + ". " + '{0:27} {1:4} {2:4} {3:5} : {4:2}'.format(team, points, diff, goalfor, goalagainst)) 
#Area of interest above^

当前输出:

所需输出:

有人知道如何编辑注释代码段中感兴趣的区域，以产生所需的输出，并将 9 排列在 13 中的 3 下方吗？我一直在尝试 .rjust(1) 但它似乎不起作用。

Python 字符串格式支持 align .

align ::= "<" | ">" | "=" | "^"

'<' Forces the field to be left-aligned within the available space (this is the default for most objects).

'>' Forces the field to be right-aligned within the available space (this is the default for numbers).

'=' Forces the padding to be placed after the sign (if any) but before the digits. This is used for printing fields in the form ‘+000000120’. This alignment option is only valid for numeric types.

'^' Forces the field to be centered within the available space.

因此使用 {:>} 进行右对齐。

演示

>>> print "{}\t{:<2}".format(1, 20) 
1   20
>>> print "{}\t{:<2}".format(1, 2)
1   2 
>>> print "{}\t{:>2}".format(1, 2)
1    2
>>> print "{}\t{:>2}".format(1, 20)
1   20

根据您的情况，只需按以下方式对齐格式即可:

print(str(1).rjust(2) + ". " + '{0:27} {1:>4} {2:4} {3:5} : {4:2}'.format("adasd", 1, -12, 1, 2))
