Slice string

Slicing operation (Slice) may acquire sub-string (part of a string) from a string. We use the square brackets, starting offset start, termination end offset step and optional steps to define a slice.

Format: [start: end: step]

• [:] Extracted from the beginning (default position 0) to the end (the default position -1) of the entire string
• [Start:] extracted from the start to the end
• [: End] extracted from the beginning to end - 1
• [Start: end] extracted from the start to the end - 1
• [Start: end: step] extracted from the start to the end - 1, each step extracting a character
• The first character position of the left / offset 0, the right of the last character position / offset is -1

Example: 
Results enter a string in reverse order returns,: such as: 'abcdef' Returns: 'fedcba'

  1 # way: string reversed step is set to -1
   2  DEF re_sort ():
   . 3      S = INPUT ( 'Enter string string: >>')
   . 4      return S [:: - 1] from # beginning to the end in steps of -1
   . 5 # re_sort obj = ()
   . 6 # Print (obj)
   . 7  
  . 8 # way: by reversing the list
   . 9  DEF re_sort2 ():
 10      S = iNPUT ( 'enter string string: >> ')
 . 11      Li = []
 12 is      for I in S:
 13 is          li.append (I)
 14      li.reverse () inverted list #
 15      return .' ' the Join (Li) is converted into a string list #
 16 obj2 = re_sort2()
 17 print(obj2)
