The problem
Implement a operate named generateRange(min, max, step), which takes three arguments and generates a spread of integers from min to max, with the step. The primary integer is the minimal worth, the second is the utmost of the vary and the third is the step. (min < max)
Job
Implement a operate named
generate_range(2, 10, 2) # ought to return record of [2,4,6,8,10]
generate_range(1, 10, 3) # ought to return record of [1,4,7,10]
generate_range(2, 10, 2) # ought to return array of [2, 4, 6, 8, 10]
generate_range(1, 10, 3) # ought to return array of [1, 4, 7, 10]
Word
- min < max
- step > 0
- the vary doesn’t HAVE to incorporate max (relying on the step)
The answer in Python code
Choice 1:
def generate_range(min, max, step):
out = []
for i in vary(min, max+1, step):
out.append(i)
return out
Choice 2:
def generate_range(min, max, step):
return [i for i in range(min, max+1, step)]
Choice 3:
generate_range=lambda a,b,c:record(vary(a,b+1,c))
