Can any one please explain me this code

Question

def f(s,k):
if k <= 0:
for n in s:
print(n)
return

# in case if k >= 1
for sl in range(len(s)):
i = sl % k
if (sl // k) % 2 == 1:
i = k - i
print(" " * i, s[sl])

# main block
n="sjjsnehbhhHCXcifOHbhjjkkk"
print(len(n))
print ()
print ()
f(n,5)

Answer 1

It is complete nonsense. First block of function will never run since k always 5 and second part of function will return type error from using string arg on modulus operator. All it should do is print 25. Why have you put this here??

Answer 2

Sorry misinterpreted this. First bit of function still seems pointless since k always 5 and presumably there in case k altered . Second bit generated a series of numbers running up and down to 8 and uses them to control spaces . Actuallly quite nice. Can watch it work with:

def f(s,k):
if k <= 0:
for n in s:
print(n)
return

# in case if k >= 1
for sl in range(len(s)):
i = sl % k
print (i)
if (sl // k) % 2 == 1:
i = k - i
print ("conditional",i)
print ( "final", i)
#print(" " * i, s[sl])

# main block
n="sjjsnehbhhHCXcifOHbhjjkkk"
print(len(n))
print ()
print ()
f(n,8)
