Python string find() examples

I'm looking for examples, but I'm not finding any.
Are there any examples on the internet? I'd like to know what it returns when it can't find something, as well as how to specify the starting and ending points, which I assume will be 0, -1.

>>> x = "Hello World"
>>> x.find('World')
6
>>> x.find('Aloha');
-1

Code (markup):

Could you please help me? But I'm not convinced.

 

Absolutely, here are some examples of how to use the find() method in Python strings:
1. Basic Usage:
x = "Hello World"
world_position = x.find('World') # Find "World"

# Output: world_position will be 6 (index of the first 'W')
2. Specifying Start and End Indexes:
x = "Hello World"

# Find "World" starting from index 7 (after the space)
start_from_seven = x.find('World', 7)

# Output: start_from_seven will be -1 (not found)

# Find "World" within a specific range (from index 2 to 9)
start_at_2 = x.find('World', 2, 9)

# Output: start_at_2 will be 6 (found within the range)

What it Returns When Not Found:
The find() method returns -1 if the substring is not found within the string.

These examples demonstrate how to use find() with different scenarios, including specifying search ranges and handling cases where the substring is not present.
