Let's say I'm parsing a file, which uses ; as the comment character. I don't want to parse comments. So if I a line looks like this:
example.com. 600 IN MX 8 s1b9.example.net ; hello! Is there an easier/more-elegant way to strip chars out other than this:
rtr = '' for line in file: trig = False for char in line: if not trig and char != ';': rtr += char else: trig = True if rtr[max(rtr)] != '\n': rtr += '\n'

To remove everything after the first occurrence of the character '-' in a string, pass the character '-' as separator and 1 as the max split value. The split('-', 1) function will split the string into 2 parts, Part 1 should contain all characters before the first occurrence of character '-'.
The most common way to remove a character from a string is with the replace() method, but we can also utilize the translate() method, and even replace one or more occurrences of a given character.
Use the String. slice() method to remove everything after a specific character, e.g. const removed = str. slice(0, str. indexOf('[')); .
I'd recommend saying
line.split(";")[0] which will give you a string of all characters up to but not including the first ";" character. If no ";" character is present, then it will give you the entire line.

just do a split on the line by comment then get the first element eg
line.split(";")[0] If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
