How to append a string in Python?
ItsMyCode |
In this tutorial, we will see different ways to append a string in Python. The most efficient methods are using the += operator , join() function, and f-strings.
We know that strings are immutable in Python, which means we cannot change the string variable’s value once it’s declared and assigned. However, we can always return a new string.
We will take a look at 3 different ways to append a string in Python.
+= operatorstring.join() methodf-strings
The
+= (plus equal) operator is similar to any other language that concatenates two strings and returns a new string in Python without changing the original string.# Python program to append to a string using += operator
first_name="Bing"
last_name=" Chandler"
# printing first name
print("The first name is: " + str(first_name))
# printing last name
print("The last name is: " + str(last_name))
# Using += operator adding one string to another
first_name += last_name
# print concatenated string
print("The concatenated string is: " + first_name)Output
The first name is: Bing
The last name is: Chandler
The concatenated string is: Bing ChandlerAnother way to append strings in Python is using the
join() method. It has an advantage over the += operator as it can append multiple strings or a list of strings. In this example, we pass a list of strings to the
join() function, which concatenates them together and returns to the output string.# Python program to append a string using join() function
first_name="Bing"
last_name=" Chandler"
# printing first name
print("The first name is: " + str(first_name))
# printing last name
print("The last name is: " + str(last_name))
# Using join() method to append a string
result= "".join([first_name,last_name])
# print concatenated string
print("The concatenated string is: " + result)Output
The first name is: Bing
The last name is: Chandler
The concatenated string is: Bing ChandlerIf you use Python 3.6 and above version, you can leverage f-strings in Python to append a string.
# Python program to append a string using f-string
first_name="Bing"
last_name=" Chandler"
# printing first name
print("The first name is: " + str(first_name))
# printing last name
print("The last name is: " + str(last_name))
# Using f-string to append a string
result= f"{first_name}{last_name}"
# print concatenated string
print("The concatenated string is: " + result)Output
The first name is: Bing
The last name is: Chandler
The concatenated string is: Bing ChandlerThe post How to append a string in Python? appeared first on ItsMyCode.
