Dovecot doesn't start

Question

Consider the following data

Non-removable Li-Po 2870 mAh battery
Non-removable Li-Po 5910 mAh battery (A3-A20-K1AY)
Non-removable Li-Po 1810 mAh battery (6.9 Wh)

I would like to extract the mAh battery numeric value from this like below

2870
5910
1810

I tried using

def func(x):
  # Split array
  ar = x.split(' mAh')

but i dont get what do i need to return

Solution

First check syntax of all configuration files in /etc/dovecot/ and /etc/dovecot/conf.d/.

Then check /etc/dovecot/conf.d/10-ssl.conf for ssl_cert and ssl_key paths. Check the files that are given, If they're not exist, use mkcert.sh to create ssl key and certificate. You can find all information here. Download dovecot-openssl.cnf and modify values. Download mkcert.sh and run it. After that change 10-ssl.conf:

ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_key = </etc/ssl/private/dovecot.pem

Restart dovecot.

log excerpt is too short

@Kondybas the rest of log is same,ierminates on startup, trys to respawn and loops.

Most probable a syntax error in one of the config files you changed. See ubuntuforums.org/showthread.php?t=1655875

@douggro Thanks man. My problem wasn't same, but I could find the solution anyway.

If you found the solution to your problem, post it as an answer. Helps those that may experience the same problem down the road.

@douggro done ;)

Its a dataframe this is just a part of data

[Wiktor Stribiżew]

If it is just a sample, what is the constant context here that can help detect the number? Is it always an integer value? Is there always Li-Po before the number? Is there always mAh after it? Note that meW's suggestion may overmatch while Jan's solution may undermatch, it depends on what requirements you want to meet here. Please be specific when it comes to regex questions.

i know that its just the column had 1200 unique values i just needed some hint how would i be able to do this

[Wiktor Stribiżew]

You have two below.
