QUESTION
Is there a simple way to remove a comma within a csv that isn't suppose to be there using AWK/ SED?
The .csv is made up of 5 columns, but that additional comma makes some rows come up with 6 columns. For example see below, the third column i am expecting to be number, but as you can see row 3 and 4 are strings.

QUESTION
I've tried a lot of differents ways, but I can't make this work. I need to capture two differents strings with regular expressions (I'm using RE on Py3).
- I need to take a substring with the same letter repetead 3 times.
- I need to take a substring that is XYX, like "BAB" or "ACA" (I don't even know how to start on this)

Answered 2020-Sep-12 at 01:50You have a few problems:
- Your regex
([a-z])\3
captures a single lowercase alpha character, then tries to match capture group 3 (which doesn't exist) - You use
re.findall(regular, string)
but you've already compiled the regex intoregular
, so you should be calling it asregular.findall(string)
- You encased your regex in single quotes (good)
'
but your regex contains a backslash. To escape it you need to user''
Fixing all of the above, we get the following.
finditer

QUESTION
I have a list of values,
ex:
['acvd MF50-107895 htrx867954', 'aasdsasdasdwg 12354 MF34-123445 hwertx86', 'sdfrgrwgvwewerf 4356 MF74-765980 hwer982fg']
Tried regex to extract the values after character "MF".
Regex expression i am trying,
x = re.search(r"MF", txt)
the values after character "MF" i need to consider only next 9 characters, the sequence of characters other than spaces and the result should be like this MF50-107895, MF34-123445, MF74-765980
.
