Match the words using re compile in Python

I'm new to Python, i have text file which consists of punctuation and other words how to recompile using specific text match.

text file looks like below actual with more that 100 sentences like below

file.txt

copy() {
foundation.d.k("cloud control")
this.is.a(context),reality, new point {"copy.control.ZOOM_CONTROL", "copy.control.ACTIVITY_CONTROL"},
context control

I just want the output something like this

copy.control.ZOOM_CONTROL
copy.control.ACTIVITY_CONTROL

i coded something like this

file=(./data/.txt)
data=re.compile('copy.control. (.*?)', re.DOTALL | re.IGNORECASE).findall(file)
res= str("|".join(data))

The above regex doesn't match for my required output. please help me on this issue. Thanks in Advance

You need to open and read the file first, then apply the re.findall method:

data = []
with open('./data/.txt', 'r') as file:
  data = re.findall(r'\bcopy\.control\.(\w+)', file.read())

The \bcopy\.control\.(\w+) regex matches

  • \bcopy\.control\. - a copy.control. string as a whole word (\b is a word boundary)
  • (\w+) - Capturing group 1 (the output of re.findall): 1 or more letters, digits or _

See the regex demo.

Then, you may print the matches:

for m in data:
  print(m)
