多次捕获同一行

Question

给定类似的文字，

A 0 1 2 3 4

我想将每个数字的A匹配为单独的匹配，例如，

re.findall(some_regex, "A 0 1 2 3 4")

会回来

[
  ["A", "0"],
  ["A", "1"],
  ["A", "2"],
  ["A", "3"],
  ["A", "4"],
]

Answer 1

    dd ='A01234'
    Result = [[dd[0],j] for i,j in enumerate(dd) if i!=0]
    #Output = [['A', '0'], ['A', '1'], ['A', '2'], ['A', '3'], ['A', '4']]

Answer 2

这是不可能的。 但是您可以轻松生成这样的列表。

x = re.findall("A*[0-9]", "A 0 1 2 3 4")
result = [["A", str(c)] for c in x]

Answer 3

试试这个，我用两个Python regex做到了。

import re

text = "A 0 1 2 3 4"  # your text here

"""
select first character which belongs to alphabetically
between a and z, lower case OR upper case. If you need
to match only upper case character, just change pattern1
into "^[A-Z]"

pattern2 will match all the string contains with digits
which mean numbers from 0-9
"""
pattern1 = "^[A-Za-z]"
pattern2 = "\d"

print([[re.search(pattern1, text).group(0), a] for a in re.findall(pattern2, text)])

输出是

[['A', '0'], ['A', '1'], ['A', '2'], ['A', '3'], ['A', '4']]

现在，您可以根据需要更改任意数量的第一个字符。
