Python summary: operators

>>> “hello” == “hello” True

Where == is the operator and the two strings the operands.

It also is possible use the same operator in the same line, and/or other ones:

>>> "hello" == "hello" == "hello"
True

>>> "hello" == "hell" + "o"
True

>>> 2 == 1 + 1
True

The operator categories are:

• Arithmetic
• Comparison
• Assignment
• Logical
• Bitwise
• Membership
• Identity

You will find everything on this page schematic way.

Finally, you must know operator functions exist (you will find them in the official documentation). For example:

>>> total = 2 + 3
>>> total
5

>>> import operator
>>> num1 = 2
>>> num2 = 3
>>> total = operator.add(num1, num2)
>>> total
5
