How do you concatenate two values in python?
String concatenation is a common practice in Python. Like with many other programming languages though, are you sure you’re using the right method? If you’re wondering how to concatenate two strings in Python and more, stay tuned. Show
In this tutorial, you are going to learn how to perform string concatenation in many unique and possible ways to help you pick the best method for your unique situation. Read on!
Prerequisites before you Concatenate Two Strings in PythonThis tutorial is hands-on and will include many different demos. If you intend to follow along, be sure you have the following:
The + OperatorOne of the most popular methods to concatenate two strings in Python (or more) is using the In a Python script, copy, paste and execute the code below. This simple script creates two string variables
The
You will see you get the same output for both examples. The Join() MethodThe To use the Python join methodInstead of a space (
You can see below that the spaces have been replaced by asterisks. Python join method with asterisksThe String Formatting % OperatorPython has a concept called string formatting. String formatting is a feature of Python that allows you to dynamically insert strings within strings with placeholders. Typically, most don’t consider using string formatting to concatenate strings but it’s possible. Let’s say you need to concatenate the three strings you’ve been working with previously. To be more specific, you’d like to concatenate two strings in Python together separated by a space. To concatenate multiple strings together with the string formatting construct Once you
have the intended string, then use the
Even if
The Format() MethodYou can also use another Python formatting technique with the
Instead of using Using the built-in string method
Once executed, you can see that Python replaces each The “placeholder” string, like using the Python format method with asterisksThe f-string ConstructFor the final way to concatenate two strings in Python, check out the You can see below the concept is the same as the other string formatting techniques. Only this time, you start the “placeholder string” with an concatenate
two strings in Python via Python f-string methodPython Gotcha: String Type ConversionsWhen concatenating strings together in Python, pay attention to types. You will come across unexpected behavior if, for example, you intend to concatenate two strings in Python together but use a non-string type instead. For example, using the Python error when using different data types
If you need to concatenate a different type like an integer, always remember to enclose it with single or double quotes, like below.
ConclusionYou should now have the proper understanding of how to concatenate two or more strings in Python using many unique methods. Whether it’s intended concatenation methods like the Which method you prefer for your real life Python project? Is there a concatenate function in Python?We can perform string concatenation using following ways: Using + operator. Using join() method.
How do I combine two string values?Concatenation is the process of appending one string to the end of another string. You concatenate strings by using the + operator. For string literals and string constants, concatenation occurs at compile time; no run-time concatenation occurs. For string variables, concatenation occurs only at run time.
What is concatenation in Python with example?Concatenation means joining strings together end-to-end to create a new string. To concatenate strings, we use the + operator. Keep in mind that when we work with numbers, + will be an operator for addition, but when used with strings it is a joining operator.
How do you concatenate items in a list in Python?To convert a list to a string, use Python List Comprehension and the join() function. The list comprehension will traverse the elements one by one, and the join() method will concatenate the list's elements into a new string and return it as output.
