String 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.

# 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])
