Question

从Splitting a string by list of indices修改代码，将固定宽度数据加载到Excel工作表中，但不了解如何修剪[List Comprehension]函数最后一行中每个数组项的结果。< / p>

注意 - 除非打印行被注释掉，否则数据不会加载到Excel工作表中。

from itertools import tee, izip_longest
import openpyxl

def fixed_reader(df, data_start, data_end, indices, ws):
    with open(df, 'rb') as f:
        for line in range(0, data_start): next(f)
        for index, line in enumerate(f):
            if index == data_end: break
            start, end = tee(indices)
            next(end)
            print([line[i:j].rstrip('\r\n') for i,j in izip_longest(start, end)])      # <<<<<
            ws.append([line[i:j].rstrip('\r\n') for i,j in izip_longest(start, end)])  # <<<<<

wb = openpyxl.Workbook()
ws = wb.active
fixed_reader('FixedWidth.dat', 3, 7, [0,1,6,8], ws)
wb.save('FixedWidth.xlsx')

Answer 1

您可以使用.strip()修剪每个字符串两端的空格，或使用.strip(' ')修剪空格。

line = line.rstrip('\r\n')
ws.append([line[i:j].strip(' ') for i,j in izip_longest(start, end)])

在列表理解中修剪数组元素
