Similar to how character data is encoded as numbers in ASCII, scientific data can also be encoded as characters. You$$ve been given a list of strings that represent $42$ sensors on an ocean submersible. The $42$ sensors are represented by $26$ capital letters and $26$ lowercase letters. By determining which sensors were triggered by a group of stimuli your organization hopes to hone in on the sources of chemical pollutants in the ocean. Write a function get$\_$indices$($sensor$,$ stimulus$)$ that takes two arguments and returns a list of integers. The first argument, sensor$,$ contains a string that is a mix of uppercase$/$lowercase letters and spaces. The spaces represent gaps where none of the sensors were triggered. The second argument, stimulus, is a string of characters which could be uppercase or lowercase. These are the targets that your organization cares about. If any characters in the second argument stimulus appear in the first argument sensor$,$ your function should return the index where they appear in sensor$.$ If there are no matches or either argument is an empty string, it should return the empty list.

NOTE: this function IS case sensitive$.$ Your solution must use an index loop $($either with range$($len$($lst$))$ or enumerate$($lst$)).$ PYTHON
