Python please

Complete the get_signature (word) function which takes a string as a parameter and and returns a "signature" of the parameter string. For example, the signature of the word "potato" is "1a2o1p2t". You can assume that the string parameter is not an empty string and contains alpha letters only. The signature contains lower case letters only. For example: Test Result 1a2o1p2t result = get_signature ('potato') print (result) result = get_signature('COMPUTER') 1clelmlolpiritlu print (result) 1e1h2110 result = get_signature('Hello') print(result)
