find in text

[DrivingMobileInnovation]

Example

txt = "Python is great and it is simple."
txt.find("is")

The output is 7 but how to find out the next "is" word?

If there are many similar words, how to find them all?

[bogdan.galiceanu]

An improvised solution could be like this:

txt="Python is great and it is simple."  #The text in which to search

word="is"  #The word to search for

length=2  #The length of the word

p=[]
for i in range(len(txt)-length):
   if(txt[i:i+length]==word):p.append(i)  #Append the position to the list

print p
