Python:使用python从一行中提取以数字开头的匹配单词

Question

我想读取文本文件并找到下面文本中以 5 开头的单词。

“状态”:“确定”}]、“PhysicalLocationString”:“rack1/chassis_u1/cpu0/pcie_slot3”、“Physloc”:“0003000101010005”、“PlaceholderNetworkDeviceFunctions”:[{“FC HBA 1”:“51: 40:2E:C0:01:C9:53:E8"}, {"FC HBA 2": "51:40:2E:C0:01:C9:53:EA"}]}}, "零件编号": "P9D94A", "序列号": "MY57470DS8", "状态": {"Health": "OK", "HealthRollup": "OK", "State": "Enabled"}}

我在另一个文件中的输出应该是

51:40:2E:C0:01:C9:53:E8 51:40:2E:C0:01:C9:53:EA

这是我的代码:

    import re
    import sys
    import os

    #get line
    with open('/root/SDFlex/work/cookbooks/ilorest/files/OP.txt', 'r') as file:
    for line in file:
    re.findall(r'\b[s]:\w+', line)
    matchedLine = line
        break


    #and write it to the file
    with open('/root/SDFlex/work/cookbooks/ilorest/files/file.txt', 'w') as 
    file:
         file.write(matchedLine)

请帮忙

Answer 1

使用模式

pattern = '"(5[^"]+)"'
re.findall(pattern, your_string)

它将搜索引号 "，后跟 5，后跟除引号之外的任何内容，然后以引号结束。分组将提取您想要的数字。
