Addition and multiplication of strings

Strings can be added, for this the sign "+" is used. This operation is called string concatenation or concatenation. 
 
Example 
s = "Hello,"
s1 = "world"
print(s + s1)
The screen will display the phrase "Hello world" (without quotes).

Python implements the operation of multiplying a string by a number: it replaces multiple addition.
 
Example 
string 
s = "world "+"world "+"world "+"world "
can be replaced by   
s = "world " *4
