In this post, We will see different ways to Reverse a string in Python.
Code 1: Using the concept of string-Slicing.

# code1
# input
string = "Biochemithon"

# reverse a string using 
# string slicing concept
reverse_string = string[ : : -1]

# show the output
print("Reverse String:",
      reverse_string)

Output:

Reverse String: nohtimehcoiB

Code 2: Using the concept of Looping and string-Concatenation.

#code2
# input
string = "Biochemithon"

# empty string
rev_str = ""

# loop through each 
# characters of the string
for i in string:
    # string concatenation
    rev_str = i + rev_str

# show the output
print("Reverse String:",
      rev_str)

Output:

Reverse String: nohtimehcoiB

Code 3: Using the concept of Reverse Looping.

# code3
# input
input_str = "Biochemithon"

# empty string
rev_str = ""

# loop through each 
# characters of the 
# string from end
for i in range(len(input_str) - 1, -1, -1):
    
    # string concatenation
    rev_str += input_str[i]

# show the output
print("Reverse String:",
      rev_str)

Output:

Reverse String: nohtimehcoiB

Code 4: Using reversed(),list() and join() function together.

# code4
# input
string = "Biochemithon"

# string reversal using 
# reversed(),list() and
# join() function of python3
rev_str = "".join(list(reversed(string)))

# show the output
print("Reverse String:",
     rev_str)

Output:

Reverse String: nohtimehcoiB

Code 5: Using the join() function and list-comprehension concept together.

# code5
# input
string = "Biochemithon"

# string reversal using 
# list-comprehension and 
# join() function of python3
reverse_str = "".join([string[i] for i in range(len(string)-1,
                                                 -1, -1)])

# show the output
print("Reverse String:",
      reverse_str)

Output:

Reverse String: nohtimehcoiB

Code 6: Using the list of characters and join() function.

#code6
# input
string = "Biochemithon"

# convert the string into
# a list of characters
char_list = list(string)

# list reversal
char_list.reverse()

# form a string from a
# list of characters
reverse_string = "".join(char_list)

# show the output
print("Reverse String:",
     reverse_string)

Output:

Reverse String: nohtimehcoiB
