Question

I want to learn python and i thought changing letters without any module or library i tried something like this but it doesn’t work:

d=list('banana')
a=list('abcdefghijklmnopqrstuvwxyz')

for i in range:
    d[i]=a[i+2]
print d

I got this error:

TypeError: 'builtin_function_or_method' object is not iterable

I would be appreciated if you help me.

In [63]: d=list('aabbcc')

In [64]: a='a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z'.split(",")

In [65]: for i,x in enumerate(d):
    d[i]=a[(a.index(x)+3)%26]

In [66]: d
Out[66]: ['d', 'd', 'e', 'e', 'f', 'f']
