reverse list python

the_list = [1,2,3]
reversed_list = the_list.reverse()
list(reversed_list) # will return [3,2,1]

# OR, better

the_list = [1,2,3]
the_list[::-1] # will also return [3,2,1]

how to reverse a list in python

how to reverse a list in python

my_list = [1, 2, 3, 4, 5]

reverse element in a list in python 3

my_list = [1, 7, 9, 11, 12, 20]
# Reverse a list by using a slice
print(my_list[::-1])

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]

reverse list python

# To reverse a list use simply: reverse() method

# Example 
list = [1, 2, 3]
list.reverse()

# Output
[3, 2, 1]

# to reverse any other type, we can use reversed() 
# The reversed() function returns an iterator that accesses the given sequence in the reverse order.

# Example 
list = [1, 2, 3]
list(reversed(list))

# Output
[3, 2, 1]

#  reversed() returns an iterator so we can loop over it

# Example
for num in reversed(list):
    print(num)

# Output
3
2
1
