python reverse slice code example

Example 1: reverse string method python

#linear

def reverse(s): 
  str = "" 
  for i in s: 
    str = i + str
  return str

#splicing
'hello world'[::-1]

#reversed & join
def reverse(string): 
    string = "".join(reversed(string)) 
    return string

Example 2: list slicing reverse python

#This option produces a reversed copy of the list. Contrast this to mylist.reverse() which
#reverses the original list
>>> mylist
[1, 2, 3, 4, 5]

>>> mylist[::-1]
[5, 4, 3, 2, 1]

Example 3: python 3 slice reverse

stringname[::-1]

Example 4: reverse function python

# The Reverse operation - Python 3:
Some_List = [1, 2, 3, 4, 1, 2, 6]  
Some_List.reverse()  
print(Some_List)
# Result: [6, 2, 1, 4, 3, 2, 1]
