I'm trying to use a single for loop to cycle over a string to print it out like this:
s u p e r n a t u r a l
u p e r n a t u r a l s
p e r n a t u r a l s u
Here is my code so far:
def main():
first_Name = "s u p e r n a t u r a l"
print(first_Name)
for i in range(len(first_Name)):
print(first_Name[i])
main()
I have it in 4 lines:
li = list('supernatural')
for c in li:
print ''.join(li)
li.append(li.pop(0))
In [11]:
S='s u p e r n a t u r a l'
SL=S.split(' ')
for i in range(len(S)-S.count(' ')):
print ' '.join(SL[i:]+SL[:i])
s u p e r n a t u r a l
u p e r n a t u r a l s
p e r n a t u r a l s u
e r n a t u r a l s u p
r n a t u r a l s u p e
n a t u r a l s u p e r
a t u r a l s u p e r n
t u r a l s u p e r n a
u r a l s u p e r n a t
r a l s u p e r n a t u
a l s u p e r n a t u r
l s u p e r n a t u r a
What a coincidence, I was doing the very same thing earlier in my consulting work! But seriously, to get you started on your homework, here are some ideas:
>>> print first_Name[0:] + ' ' + first_Name[:0]
s u p e r n a t u r a l
>>> print first_Name[1:] + ' ' + first_Name[:1]
u p e r n a t u r a l s
>>> print first_Name[2:] + ' ' + first_Name[:2]
u p e r n a t u r a l s
Looks promising, at least the even numbers...
How to iterate through just even numbers?
>>> help(range)
step is your friend here.
>>> range(0, len(first_Name), 2)
[0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22]
I bet you can (and should) figure out the rest.
A simple way of doing this:
#!/usr/bin/env python
def rshift(s, i):
i = i % len(s)
return s[-i:] + s[0:-i]
if __name__ == '__main__':
s = "12345"
for i in range(len(s)):
print rshift(s, -i)
To me, this is made for a deque
import collections
d = collections.deque('supernatural')
for _ in range(len(d)):
print(' '.join(d))
d.rotate(-1)
Prints out:
s u p e r n a t u r a l
u p e r n a t u r a l s
p e r n a t u r a l s u
e r n a t u r a l s u p
r n a t u r a l s u p e
n a t u r a l s u p e r
a t u r a l s u p e r n
t u r a l s u p e r n a
u r a l s u p e r n a t
r a l s u p e r n a t u
a l s u p e r n a t u r
l s u p e r n a t u r a
