Python code for the Quick Sort Algorithm
def quicksort(x):
if len(x) == 1 or len(x) == 0:
return x
else:
pivot = x[0]
i = 0
for j in range(len(x)-1):
if x[j+1] < pivot:
x[j+1],x[i+1] = x[i+1], x[j+1]
i += 1
x[0],x[i] = x[i],x[0]
first_part = quicksort(x[:i])
second_part = quicksort(x[i+1:])
first_part.append(x[i])
return first_part + second_part
alist = [54,26,93,17,77,31,44,55,20]
quicksort(alist)
print(alist)

Bueno pues la razón de que no funcione es que no estamos teniendo en cuenta el tipo de dato que comparamos:
The data type is not integer...

def sort(num):
if len(num) < 2:
return num
else:
piv = int(num[0])
less = [x for x in num[1:] if int(x) < piv]
print("less",less)
higher = [x for x in num[1:] if int(x) > piv]
print(higher)
return sort(higher) + [piv] + sort(less)
for y in range(0, input()):
list = raw_input()
alist = list.split()
listOrg = sort(alist)
print(listOrg)

simple method

a= [4,7,1,2,3,9,7,0,4,56,3]
for i in range(len(a)):
for j in range(len(a)):
if a[i]<a[j]:
a[i],a[j]=a[j],a[i]
print("The sorted list is ",a)

@pete312 use pypy3 instead of python to see some BIG RUNNING TIME DIFFRENCE
