bookString Slicing 2/2

We can also get a substring from a string using simple slicing.

First, let's look at the syntax of slicing. string[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.

123456
# Creating a string string = 'ABCDEFGHIJKLMNO' print("Initial string: ", string) string_1 = string[7:13] print("Elements in a range 7-13: ", string_1)
copy
123
# Print elements from a pre-defined point to end string_2 = string[5:] print("Elements from 6th element till the end: ", string_2)
copy
1234
# Print all elements from beginning till end string_3 = string[:] print("All elements: ", string_3)
copy
