String 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)


              123
            
# Print elements from a pre-defined point to end
string_2 = string[5:]
print("Elements from 6th element till the end: ", string_2)


              1234
            
# Print all elements from beginning till end
string_3 = string[:]
print("All elements: ", string_3)
