: Write a while-loop to let the snail go up and down. The loop should terminate when the snail is solidly on top of the well. Inside the loop, print the detail of the simulation so we can track the simulation. It is possible that the snail climbs up 1 cm and slides down 2 cm in the same minute. That is why the location of the snail can be a negative number. You should test this part completely before moving to the next step

Part d: float check string has a method s.isdigit() that returns true if string s contains only digits and false otherwise, i.e. s is a string that represents an integer. write a function named float_check that takes one parameter that is a string and returns true if the string represents a float and false otherwise. for the purpose of this function we define a float to be a string of digits that has at most one decimal point. note that under this definition an integer argument will return true. remember “edge cases” such as “45.” or “.45”; both should return true. for example: float_check('1234') returns true float_check('123.45') returns true float_check('123.45.67') returns false float_check('34e46') returns false float_check('.45') returns true float_check('45.') returns true float_check('45..') returns false
