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)

Conclusion

In this post, we have explained three-way to concatenate strings in Python.

  • + operator
  • +=  
  • Join Method
