Python reversed() function examples

Simple example code Reverse the sequence of a list, and print each element:

list1 = ["A", "B", "C", "D"]

res = reversed(list1)
for x in res:
    print(x)

Output:

Print reversed list

list1 = ["A", "B", "C", "D"]

print(list(reversed(list1)))

Output: [‘D’, ‘C’, ‘B’, ‘A’]

Using reversed() in string, tuple, list, and range

# for string
seq_string = 'Python'
print(list(reversed(seq_string)))

# for tuple
seq_tuple = ('P', 'y', 't', 'h', 'o', 'n')
print(list(reversed(seq_tuple)))

# for range
seq_range = range(5, 9)
print(list(reversed(seq_range)))

# for list
seq_list = [1, 2, 4, 3, 5]
print(list(reversed(seq_list)))

Output:

[‘n’, ‘o’, ‘h’, ‘t’, ‘y’, ‘P’]
[‘n’, ‘o’, ‘h’, ‘t’, ‘y’, ‘P’]
[8, 7, 6, 5]
[5, 3, 4, 2, 1]
