一、序
在一些情况下，导出txt的配置信息，但是又有特定的规律。在这种情况下读取配置
二、问题分析
我们首先肯定是通过关键字定位文本位置，但txt文件我们会面临两种情况：
1.关键字与文本在同一行
2.关键字与文本不在同一行
3.判断条件
例如MAC地址只有有IP的才读取，没有IP的就不读取
三、解决思路
1.关键字与文本在同一行情况
def sameLine(txt_Path, needWord):
with open(txt_Path, "r") as file:
words = needWord
returnWord = []
for line in file.readlines():
if line.strip().startswith(words):
returnWord.append(line.strip().replace(words, ""))
if len(returnWord) == 0:
returnWord.append("无")
return returnWord
</code></pre>
2.关键字与文本不在同一行情况
# 得到指定关键字行数
def readTxtResult(txt_Path, needWord):
with open(txt_Path, "r") as file:
row = []
words = needWord
for i, line in enumerate(file.readlines(), start=1):
if words in line.strip():
b: int = i
row.append(b)
else:
var = ()
return row
# 得到指定一行的文本
def getRowWord(txt_Path, row):
with open(txt_Path, "r") as file:
lines = file.readlines()
word = lines[row].strip()
return word
</code></pre>
- 如果是有判断条件，先去需要的地方获取判断条件，自定义判断条件
