string slice() python code example
Example 1: python string slicing
my_string = "Hey, This is a sample text"
print(my_string[2:]) #prints y, This is a sample text
print(my_string[2:7]) #prints y, Th excluding the last index
print(my_string[2::2]) #prints y hsi apetx
print(my_string[::-1]) #reverses the string => txet elpmas a si sihT ,yeH
Example 2: python slice
# array[start:stop:step]
# start = include everything STARTING AT this idx (inclusive)
# stop = include everything BEFORE this idx (exclusive)
# step = (can be ommitted) difference between each idx in the sequence
arr = ['a', 'b', 'c', 'd', 'e']
arr[2:] => ['c', 'd', 'e']
arr[:4] => ['a', 'b', 'c', 'd']
arr[2:4] => ['c', 'd']
arr[0:5:2] => ['a', 'c', 'e']
arr[:] => makes copy of arr
