Search Python string with index method

Search a string

We can use index method to find a substring. It has the following syntax.

Like find, but raises ValueError if not found instead of returning -1.

searchStr =  "Red Blue Violet Green Blue Yellow Black"
print searchStr.index("Blue")

The code above generates the following result.

Search from 20th character.

searchStr =  "Red Blue Violet Green Blue Yellow Black"
print searchStr.index("Blue",20)
