Скачать или смотреть use of "+" plus operator in python

Working with Operator
Operators are special symbols that work on data / variables.
. Each operator performs its own specific function.
Working of “+” operator (in Python) with
1. Numbers (Used to add numbers and get the total)
2. Characters/Strings (Used to merge/add the given Strings and get new string)

When "+" works with numbers, this symbol adds the numbers and returns the total
For example
a=10
b=20
c=a+b the value of c=10+20
c=30
Another example
x=15
y=25
z=x+y the value of z=15+25
z=40

When “+” works with strings / character(s) then “+” Symbol called concatenation operators.
It joins/merge the given strings/character(s)
Note:-
A. Python Strings are characters enclosed in
1. Single quotation Mark
2. Double quotation Mark
3. Triple quotation Mark
B. All data should be string/ character to perform concatenation.
C. One string and one integer generate error.

Examples
If x=”18”
Y=”2”
Then z=x+y
z=”18”+”2”
z=”182”

another example:-
if a=”I”
b=”Love”
c=”Python”
then find the value of d, d=a+b+c

1. All the data should in quotes (‘Single, Double “ ”,triple ‘’’) other than number data.
2. You have to identify the type of data
a. For number it should be without quotes.
b. For strings/charterers it should be with quotes.
3. After getting the data type you are ready to work
a. If numbers then do add and get the total
4. If String, join string to string and get a new string.
5.
If you provide a number, but in quotes it will be treated as a string / character in this case
The "+" operator merges /joins these two numbers instead of adding.
