A function to print the positions of a letter in a string?

Question

for example string="sjdhsghy"
h=[3, 6]

Answer 1

a='sjdhsghy'
l=[]
for i,x in enumerate(a):
if x=='h':
l.append(i)
print(l)

Answer 2

It can be done in a different ways. Here, for example, recursive function, that appends existing list:

string="sjdhsghy"
letter="h"
indeces=[]

def findindeces(s, l, startindex):
i=s.find(l,startindex)
if(i!=-1):
indeces.append(i)
findindeces(s,l,i+1)

findindeces(string,letter,0)
print(indeces)
