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.

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])
