Interception of Python strings

There are usually multiple characters in a string in Python, how do I intercept it?

Example: name = ' My name is jockey '

We first numbered this string, starting with 0:

1. Print a character

>>> print (name[0])
M
>>> print (name[11])
J

2. Print one of the characters

If the side of the colon is empty to identify the end, the value is followed by the left closed right open principle, that is: [)

>>> print (name[3:14])
Name is JOC

>>> print (name[6:])
E is jockey

>>> print (name[:16])
My name is Jocke
>>> print (name[:17])
My name is jockey

3. Reverse Intercept

The reverse intercept is sorted from right to left, starting with 1 instead of starting at 0.

Segment printing or left-to-right open, consistent with positive alignment

>>> print (name[-1])
Y
>>> print (name[-6])
J

>>> print (name[-9:-1])
Is Jocke

Draw on an interesting exercise from elsewhere:

"Find the Devil in your friend."

Word = ' friends '

Find_the_evil_in_your_friends = word[0] + word[2:4] + word[-3:-1]

Print (Find_the_evil_in_your_friends)

Execution Result: Fiend Devil
