How to concatenate strings in python

In this lesson I'll explain how to do string concatenation in the Python language.

What is a string? A string is a sequence of alphanumeric characters (letters, numbers and symbols). For example "Python Tutorial" is a string.

In the python language to concatenate and join two or more strings you have to use the addition operator +

stringa1+stringa2

If the operands are alphanumeric values (eg strings or alphanumeric variables) the + operator joins the two strings, transforming them into a single string.

I'll give you some practical examples

Type and run this code

print("hello"+"world")

This script concatenates two strings and displays the result on the screen

helloworld

Example 2

Now write this other example code

Assign alphanumeric values to two variables (a, b).

Then it concatenates the two variables into a third variable (c).

a="Python"
b="Tutorial"
c=a+b
print(c)

The output on the screen is as follows:

PythonTutorial

Example 3

This script combines constants and alphanumeric variables with each other.

a="Python"
b="Tutorial"
print(a+" "+b)

The output on the screen is the union of the three strings

Python Tutorial

In the latter case there is a space between the values of the two variables, because in the concatenation there is also the alphanumeric constant.
