String index is started counting at 0 to (n-1) in python. 

How work of slice in the string:
slicing= name[int_start: int_end]

Negative indexing:
String index is started negative indexing at -1  to (n-1) in python.

name = "Pirates" #0123456

print(name[-5:-1]) #return same as [2:6]

print(name[2:6])

Output

rate rate

Slicing with skip value:

name = "Pirates" #0123456

print(name[0:6:4]) # return 0 and 4 index

Output

Pt

we can slice whatever we gain from a string.

Advance Slicing Techniques:

name = "Pirates" #0123456

print(name[:6]) # advance Slicing

print(name[0:]) # advance Slicing
