Finding index of substring

Question

How can I find the index of a substring(for both single and multiple occurence) in python without using any in-built function?

Answer 1

Incase you want a string

x = "hello world hello I am namit jain hello everyone"
y = "hello"
for i in range(len(x) - len(y)):
if x[i] == y[0] and x[i + 1] == y[1] and x[i + 2] == y[2] and x[i + 3] == y[3] and x[i + 4] == y[4]:
print(x.index(x[i])

But you can simply use the re module
