Question

Using PYTHON (LOOPS, IF STATEMENTS )

I should write a function buckets that  takes two arguments: (bucketCount, an integer specifying the number of “buckets” to return and numberLs, a list of numbers )

buckets should split the range of values in numberLs into bucketCount sub-ranges. Specifically buckets should return a list-of-lists of length bucketCount. Each list in the returned list-of-lists represents a “bucket”. Each bucket should contain the numbers from numberLs whose values are greater than or equal to min(numberLs) + (i * bucketSize) and less than min(numberLs) + (i+1) * bucketSize (except for the last bucket which should include values less than or equal to (i+1) * bucketSize). Where i is the “buckets” index and bucketSize is (max(numberLs) - min(numberLs))/bucketCount

print(buckets(2,[1, 10, 2, 20, 3, 30, 40]))
#it should return [[1, 10, 2, 20, 3], [30, 40]]
print(buckets(2,[3, 2, -5, 6, 100]))
#It should return [[3, 2, -5, 6], [100]]

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

Note: Please maintain proper code spacing (indentation), just copy the code part and paste it in your compiler/IDE directly, no modifications required.

#code

''' required method '''
def buckets(bucketCount, numberLs):
    #creating an empty list to store the result
    result=[]
    #finding minimum and maximum values from numberLs
    min_val=min(numberLs)
    max_val=max(numberLs)
    #finding bucketSize
    bucketSize=(max_val-min_val)/bucketCount
    #looping for bucketCount times
    for i in range(bucketCount):
        #creating an empty list to store values that satsfy the condition
        row=[]
        #looping through each number in numberLs
        for value in numberLs:
            #checking if value >= min_val+(i*bucketSize)
            if value>=min_val+(i*bucketSize):
                #if this is last bucket, checking if value is less than OR EQUAL to
                # min_val+((i+1)*bucketSize)
                if i==bucketCount-1:
                    if value<=min_val+((i+1)*bucketSize):
                        #appending to row
                        row.append(value)
                #otherwise checking if value is less than min_val+((i+1)*bucketSize)
                elif value<min_val+((i+1)*bucketSize):
                    #appending to row
                    row.append(value)
        #appending row to result
        result.append(row)
    #returning result
    return result


#testing buckets method
print(buckets(2,[1, 10, 2, 20, 3, 30, 40]))
print(buckets(2,[3, 2, -5, 6, 100]))

#OUTPUT

[[1, 10, 2, 20, 31, [30, 40]] [[3, 2, -5, 6], [100]]
