Python PCEP Operators

1. Module 1
operations, basic operators,data types, variables,
basic input-output
Operators

2. Module 1 Operators
Basic operators
+ - * / // % **
Data and operators when connected
together form expressions.

3. Module 1 Operators
Exponentiation, multiplication
print(2 ** 3)
print(2 ** 3.)
print(2. ** 3)
print(2. ** 3.)
8
8.0
8.0
8.0
When both ** arguments are integers, the result is
an integer, too;
When at least one ** argument is a float, the result
is a float, too.
print(2 * 3)
print(2 * 3.)
print(2. * 3)
print(2. * 3.)

6. Module 1 Operators
List of priorities
Priority Operator
1 +, - unary
2 **
3 *, /, //, %
4 +, - binary
Left-sided binding
• print(9 % 6 % 2)
Right-sided
binding
• print(2 ** 2 ** 3)

7. Module 1 Operators
Key takeaways
• An expression is a combination of values;
• Operators are special symbols or keywords;
• Arithmetic operators in Python;
• A unary operator, a binary operator;
• The hierarchy of priorities;
• The exponentiation operator uses right-sided binding.
