Question

我想：

将CSV格式的数据导入python列表/数组
右对齐字符串
将输出写为文本文件

例如，我想转换csv数据，例如：

11111, 22,

333, 4444

分为：

   11111      22

     333    4444

我的代码目前看起来像：

import csv

input_file = "csv_file.csv"
my_data = csv.reader(open(input_file, "rb"), delimiter=',')

for i,j in my_data:
    x = ('%-15s %s\n' % (i,j))

with open('my_output.txt', 'w') as file:
    file.writelines(x)

谢谢

我只会rjust每个元素单独''.join：

''.join(elem.rjust(8) for elem in (i,j))

或者全力以赴：

def join_line(line_iter):
    """
    Take a iterable containing strings and right justify each 
    at 8 spaces before joining
    """
    return ''.join(elem.rjust(8) for elem in line_iter)

with open('output','w') as f:
    f.writelines((join_line(row)+'\n') for row in csv_file)

Python - 将空白空间写入导入的CSV数据
