bookString Slicing 1/2

To get get a substring from a string, you have to use slice() function.

The syntax of slice() function:. slice(start: end: step) respectively:

  • start -- the index from which to start slicing.
  • end -- the index at which the slicing ends.
  • step -- this parameter determines the increments between the indices.

Ending index is up to but not including.

Indexing starts from 0.

It's time for an example.


              
12345678910

            
# String slicing
string ='Python'
# Using slice constructor
string_1 = slice(4)
string_2 = slice(2, 6, 2) 
string_3 = slice(-1, -5, -2)
  
print(string[string_1]) 
print(string[string_2]) 
print(string[string_3])
copy

Task

You have such string hello, world. Using slice() constructor you have to get such string: ll, eowl, world. Use only positive indexing.
