Python strings and if statements -


i having trouble python code. question supposed write program below code. code works fine in wing ide when run different input values steps, when submit system checks code errors shown below. in advance help. code below.

def activity_level_from_steps(steps):    """takes amount of steps , returns level of exercise equals"""     steps = int(steps)     if steps < 1:         level = 'alive?'     elif steps >= 1 , steps < 5000:         level = 'sedentary'     elif steps >= 5000 , steps < 7500:         level = 'very low'     elif steps >= 7500 , steps < 10000:         level = 'low'     elif steps >= 10000 , steps < 12500:         level = 'active'     else:         level = 'very active'      return level

the question required solve

first, you'll need indent function body properly, since indentation important (tm) in python.

secondly, have indented return statement @ same level else. mean return invoked when else clause executed. since function doesn't return returns none default, function shown returning none other cases.

def activity_level_from_steps(steps):     """takes amount of steps , returns level of exercise equals"""     steps = int(steps)      if steps < 1:         level = 'alive?'     elif steps >= 1 , steps < 5000:         level = 'sedentary'     elif steps >= 5000 , steps < 7500:         level = 'very low'     elif steps >= 7500 , steps < 10000:         level = 'low'     elif steps >= 10000 , steps < 12500:         level = 'active'     else:         level = 'very active'      return level

this can simplified, since each elif need check next step in activity stair:

    if steps < 1:         level = 'alive?'     elif steps < 5000:         level = 'sedentary'     elif steps < 7500:         level = 'very low'     elif steps < 10000:         level = 'low'     elif steps < 12500:         level = 'active'     else:         level = 'very active'

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
