Method Name:
index
Method Signature:
index(sub[, start[, end]])
Method Overview:
- The index method returns the lowest index at which a substring is found.
- Start and End indexes can be specified for searching the substring.
- Behavior of the index() method is same as find() but index() raises an exception of type ValueError when the substring is not found in the string.
Example:
|
quote = "All grown-ups were once children" substr = "children" pos = quote.index(substr)
print("The substring '{}' was found at position:{}".format(substr,pos))
quote = "The Earth is not just an ordinary planet" substr = "Earth" startPos = 3 endPos = len(quote)
# search the substring with the start and stop positions specified pos = quote.index(substr, startPos, endPos)
print("The substring '{}' was found at position:{}".format(substr,pos)) |
Output:
|
The substring 'children' was found at position:24 The substring 'Earth' was found at position:4 |
