Cutting and slicing strings and examples of substring

Python slicing is a computationally fast way to methodically access parts of String. The colons (:) in subscript notation (subscriptable[subscriptarg]) make slice notation - which has the optional arguments, start, stop, step
string[start:stop:step]. Using slice you can get first and last character of a string. You can get string between first and last character. Print string between range.

test = "Python Programming"
print("String: ", test)
 
# First one character
first_character = test[:1]
print("First Character: ", first_character)
 
# Last one character
last_character = test[-1:]
print("Last Character: ", last_character)
 
# Everything except the first one character
except_first = test[1:]
print("Except First Char.: ", except_first)
 
# Everything except the last one character
except_last = test[:-1]
print("Except First Char.: ", except_last)
 
# Everything between first and last two character
between_two = test[2:-2]
print("Between two character: ", between_two)
 
# Skip one character
skip_one = test[0:18:2]  # [start:stop:step]
print("Skip one character: ", skip_one)
 
# Reverse String
reverse_str = test[::-1]
print("Reverse String: ", reverse_str)
