String concatenation in Python
In Python, strings can be concatenated by using the + operator. Following are a few examples of Python string concatenation.
Python Concatenation example
Following example simply joins two sentences and displays it.

String concatenation of two variables
In the following example of Python string concatenation, we will use two string variables and combine those by using the ‘+’ operator. See the code with output!

str1 = “This is Python Tutorial.”
str2 = “This is concatenation chapter”
print (str1 + ” “ + str2)
|
The output will be:
This is Python Tutorial. This is concatenation chapter
What happens if Int is concatenated?
If an Int is tried to concatenate with string then an error will be generated.

str1 = “This is Python Tutorial.”
str2 = “This is concatenation chapter”
int1 = 123
print (str1 + ” “ + int1)

This will be output with an error message:
Traceback (most recent call last):
File “C:PythonProgramsshell.py”, line 4, in <module>
print (str1 + ” ” + int1)
TypeError: Can’t convert ‘int’ object to str implicitly
You have to convert an int to the string by using the Python str method in order to concatenate this. See example below:

str1 = “This is Python Tutorial.”
str2 = “This is concatenation chapter”
int1 = 123
print (str1 + ” “ + str(int1))

The output will be:
