[英]Python - how to match specific words / digits from multiple lines in a text file and store them in separate lists
[英]Using python how can I separate lines of text using pattern matching and store them into different text file
下面是代碼示例,它是一個很長的日志,但我剛剛粘貼了它的一個片段。 我需要提取模式之間的行 ---------------------------------- 並將每個信息存儲在分別為每個單獨的文本文件。
Like:
------------------
info1
------------------
info2
------------------
info3
------------------
Output:
fetch info1 and store it into file1.txt
fetch info2 and store it into file2.txt
fetch info3 and store it into file3.txt
And so on...

**This is the text data :**

Acc_Ref Data front-end side functionality with validation done.

嘗試這個:
lg = open("log.txt")
fl = open("temp.txt", 'w')
cnt = 0
for i in lg:
if i == "------------------------------------------------------------------------\n":
fl.close()
cnt += 1
fl = open("file{}.txt".format(str(cnt)), 'w')
else:
fl.write(i)
fl.close()
lg.close()
這甚至可以在不使用正則表達式的情況下完成。
我假設,主文本文件與名稱“text.txt”位於同一目錄中,並且您希望將文件保存在同一目錄中。 請根據您的需要更改文件路徑。這應該適合您:
with open('./text.txt', 'r') as content:
paragraphs = list(filter(lambda x : x != '', content.read().split('------------------------------------------------------------------------')))
for index, para in enumerate(paragraphs):
filepath = './new_file' + str(index) + '.txt'
with open(filepath, 'w') as file:
file.write(para)
如果日志文件不是太大(例如 1GB),你可以這樣做:
with open('log.log') as f:
content = f.read()
content = content.split('------------------------------------------------------------------------')
for idx, info in enumerate(content):
with open('info{}.txt'.format(idx + 1), 'w') as f:
f.write(info)
我認為“========...”也是模式之一,因此我使用了 re 模塊...因此,如果需要,您可以添加更多模式 [最初有 re.compile( "-+|=+")]
import re
with open("file.txt", "r") as input_file:
text = input_file.read()
regex = re.compile("-+")
mo = regex.findall(text)
text = text.split("\n")
mo_wanted_patterns = [pattern for pattern in mo if len(pattern) > 5]
print(mo_wanted_patterns)
output_text = []
for index,line in enumerate(text):
if line in mo_wanted_patterns:
filepath = 'new_file' + str(index) + '.txt'
with open(filepath, 'w') as file:
file.write("\n".join(output_text))
output_text = []
elif line not in mo_wanted_patterns:
output_text.append(line)
編輯:我注意到它的代碼比其他人提供的要復雜得多。 實施正則表達式使事情變得更加復雜,但很想知道它是否適合您
