python - 根据模板使用空格分割字符串

Question

我有以下字符串标题(模板):

Port          Name               Status    Vlan      Duplex  Speed   Type

和字符串str:

Eth1/2        trunk to dg-qwu-29 connected trunk     full    1000    1/10g

使用 header ，如何将 str 剥离到以下列表？

[Eth1/2, trunk to dg-qwu-29, connected, trunk, full, 1000, 1/10g]

Answer 1

以下内容假设行和标题遵循空白掩码。也就是说，标题文本与行列对齐。

import re
header =  "Port          Name               Status    Vlan      Duplex  Speed   Type"
row    =  "Eth1/2        trunk to dg-qwu-29 connected trunk     full    1000    1/10g"
# retrieve indices where each header title begins and ends
matches = [(m.group(0), (m.start(), m.end()-1)) for m in re.finditer(r'\S+', header)]
b,c=zip(*matches)
# each text in the row begins in each header title index and ends at most before the index 
# of the next header title. strip() to remove extra spaces
items = [(row[j[0]:(c[i+1][0] if i < len(c)-1 else len(row))]).strip() for i,j in enumerate(c)]
print items

以上输出:

['Eth1/2', 'trunk to dg-qwu-29', 'connected', 'trunk', 'full', '1000', '1/10g']
