String Concatenation in Python

Question

In the previous post, we explained String in Python. In this post, we are going to learn the best ways of string concatenation in Python.

Python represents "string" as a text, it doesn't have a "character" data type.

What is string concatenation?

In Python, there are a few ways to concatenate or combine strings, as we know everything in Python is an object, so the new string is a string object.

String concatenation in Python:

To concatenate string in Python, you can use the following:

• + operator
• +=  
• Join Method

The + operator

• Concatenate one or more string.
• once the string object created, it can't be changed. (this means immutable)
• It is recommended for a few strings.

Ex:

firstName="Hamza "
lastname="Mohammed"
print(firstName+lastname)# the output will be Hamza Mohammed

---

+= concatenate operator

Besides the + operator, we can use the += operator to concatenate string in Python.

Ex:

firstName="Hamza "
lastname="Mohammed"
firstName+=lastname
print(firstName)# the output will be Hamza Mohammed

---

join() method

• It is used with iterators.
• It is recommended in case you have many strings.

Ex:

colorLists=['Red', 'Yellow', 'Black']
str_concat = ", ".join(colorLists)
print(str_concat)
