Hi,everyone.
My name is Sai krishna, and I'm new to Python as well as Programming.
Welcome.
I wanted to print out all the combinations of a given word.
More precisely you want to print all the combination of the letters in
a given word.
I am doing it this way:
n='cat'
def arrange(n):
if len(n)==1: #length of word is 1
print n
elif len(n)==2: # length of word is 2
print n[0]+n[1]
print n[1]+n[0]
elif len(n)==3:
print n[0]+n[1]+n[2]
print n[0]+n[2]+n[1]
print n[1]+n[0]+n[2]
print n[1]+n[2]+n[0]
print n[2]+n[0]+n[1]
print n[2]+n[1]+n[0]
This process is quite lengthy, and I have managed to do this for word
containing 5 letters,i,e.,120 combinations
Is there a better way?
For starters see http://en.wikipedia.org/wiki/Combination and
http://en.wikipedia.org/wiki/Combinadic. At the bottom of the latter is
a link
I have not examined that but it seems to be what you want.
