10 - In an examination, 500 students appeared. Out of these students, 38 % got A+ grade, 45 % got B+ and the remaining just passed. Assuming that no student failed, find the number of students who got A+, B+ and the number of students who just passed.(Python code)
Python question please include all steps and screenshot of code. Also please provide a docstring, and comments throughout the code, and test the given examples below. Thanks. Develop function fingerprint() that takes text (as a string) as input and creates andreturns the text “fingerprint” obtained as follows: replace each word in the text by itslength (i.e., the number of letters) and concatenate these numbers.>>> fingerprint('This is a secret message')'42167'>>> fingerprint('This message has a different fingerprint')'4731911'>>> fingerprint('Very Short')'45'
