Trim string till any specified character

Question

Need Generalize Solution I have a string and want to remove all characters before the colon (:). Like this:

oldstring = 'Resolution: 1366 x 768'
newstring = '1366 x 768'

Answer 1

you can use:

newstring = oldstring.split(':')[-1].strip()

for your example:

newstring, _ = oldstring.split(':')
newstring = newstring.strip()

Answer 2

You may use

newstring = oldstring[oldstring.find(":") + 1:]

It will remove everything before the first :.

To remove everything before the last :, use this instead :

newstring = oldstring[oldstring.rfind(":") + 1:]

---

If you want to remove spaces that can trail the :, add strip()

newstring = oldstring[oldstring.find(":") + 1:].strip()

---

This code will not throw an Exception if there is no : in the string, it will simply not remove anything. If you want to have an Exception in order to handle it, you should use

newstring = oldstring[oldstring.index(":") + 1:]

or

newstring = oldstring[oldstring.rindex(":") + 1:]

Answer 3

It's also an option:

newstring = oldstring[oldstring.find(':') + 1:]
