Append Character to String In Python (6 Methods)

Using the += Operator

my_string = ""                      # Original string
character = "a"                    # Character to append
my_string += character             # Append character using += operator
print(my_string)                    

Output:

a

Using String Concatenation

my_string = ""                      # Original string
character = "b"                    # Character to append
my_string = my_string + character   # Concatenate original string and character
print(my_string)                  

Output:

b

Using a List with the join() Method

my_list = []
character = "c"                    # Character to append
my_list.append(character)           # Append character to the list
my_string = "".join(my_list)        # Convert the list to a string using join() method
print(my_string)                    # Output: "c"

Output:

c

Using Formatted String

my_string = "Hello"                 # Original string
character = "d"                    # Character to append
my_string = f"{my_string}{character}"   # Append character using formatted string
print(my_string)                  

Output:

Hello d

Using the str.format() Method

my_string = "World"                 # Original string
character = "e"                    # Character to append
my_string = "{}{}".format(my_string, character)   # Append character using str.format() method
print(my_string)                    

Output:

Worlde

Using the join() Method with a List Comprehension

my_string = ""
characters = ['f', 'g', 'h']       # Characters to append
my_string = "".join([character for character in characters])  # Append characters using a list comprehension
print(my_string)                   

Output:
