''' Purpose: consider string find() function

text = input( "Enter text: " )

substring = input( "Enter substring: " )

print()

### find occurrences
# NEW FUNCTION: find() -> s.find( what we want to find ) -> tells us index of where substring occurs
# If it occurs, it'll give us the index! Otherwise, it'll give us -1 (not found)

i1 = text.find( substring ) # Finds the first occurence of substring

i2 = text.find( substring, i1 + 1 ) # Finds the occurence - starts to look at the specified index and beyond

i3 = text.find( substring, i2 + 1 ) # Finds the occurence - starts to look at the specified index and beyond

print( "text.find( substring ):", i1, "      # first occurrence" )
print( "text.find( substring,", i1 + 1, "):", i2, "   # second occurrence" )
print( "text.find( substring,", i2 + 1, "):", i3, "   # third occurrence" )
