Retrieve part of string after underscore

Question

I know that in Python you can use the array selector to retrieve a certain part of a string, ie me.name[10:] to get just the last 10 characters.

but how would you retrieve just the part of a string after an underscore ie _ using a single expression? For example if my string is "stringcharThatChange_myname"

How would I extract just 'myname' ? I'm confined to using Python 3.5.1

See the duplicate, `variable.partition("_")[-1]` or `variable.split("_", 1)[-1]`. — Martijn Pieters, Jan 24 '20 at 20:17
Also it is not an "array selector". It's called a slice. You can also do `my_list[slice(0, 5, 3)]`. Lastly, as stated by the last comment, the last ten of a sliceable container is `my_list[-10:]`. — Error - Syntactical Remorse, Jan 24 '20 at 20:28

You could use split.

test_string = "stringcharThatChange_myname"
print(test_string.split('_')[1]) # myname
